All about the hp colour laserjet 3600n

Design With a price tag of Ј480, the new HP Colour LaserJet 3600n is small, weighs 27kg and has deep handholds, so one person can carry it easily. At 15.7 by 15.7 by 17.7 inches (HWD), this laser printer can easily fit into a busy home office or individual office in a large company, should you need this level of speed and paper capacity. Its simplistic design makes jam-clearing and maintenance uncomplicated. However, the wall and hinges don’t appear to be too sturdy. It can be setup in the standard manner applicable to its class of printers, and the network installation routine is fully automated. Paper Handling The HP Colour LaserJet 3600n offers high-speed performance, with an engine rated at 17 pages per minute (ppm) for both colour and monochrome, fairly good graphics quality, even better text, and photographs that are good enough for client newsletters and the like. HP has also included an Ethernet connection for easy sharing over a network. However, the main paper tray feels a little unsteady and has nothing to stop it when pulled out, so users should be careful not to drop it. The paper-length and paper-width guides are easy to adjust. The printer has a 100-sheet auxiliary feed in addition to the enclosed 250-sheet tray. You can boost this number to 850 by adding a 500-sheet feeder for Ј280. Features A two-line backlit LCD screen on the 3600n's top panel displays a complete set of menus, which is easy to navigate with buttons for going through menus, selecting items and going back. This printer comes with 64MB of memory and unfortunately you cannot expand that, nor add a duplexer, which makes expansion options very limited. If you need the extra memory, then consider HP's 3600dn, a Ј670 model with a duplexer and twice the memory. Performance The 3600n prints black text at a reasonable 13ppm and colour graphics a bit faster, at 13.5ppm. In contrast, the Lexmark C522n prints text at 14.2ppm and graphics at 12.3ppm. However, if saving money is your real priority, and you don't print much colour, consider Ricoh Aficio G700, which prints fine text at 12.1ppm but misses the cut on graphics speed and quality. The 3600n disappoints the user with its print quality. In a few tests carried out by popular technology magazines, the text looked greyish instead of black, showed some roughness in large point sizes, and lost fine strokes. This is also the case with some of the 4-point output, which looked slightly grey, rather than black. Colour graphics did not negotiate shading ramps smoothly and produced blockish transitions. However, the printer makes the cut with colour accuracy and detail. Additionally, it prints greyscale photos very well, with fine detail and smooth shading. Graphics are easily good enough for internal business use, but not satisfactory for handing out to important clients or customers. The most important issue in a number of tests was misregistration, with the colours slightly out of alignment. It resulted in a noticeable white gap between some blocks of colours, around some lines, and around some colour text on a colour background. Thin lines also tended to disappear. Additionally, colours tend to shift toward darker shades, losing detail in dark areas and making some colours look muddy. On the whole, the 3600n's text output has high enough quality for most purposes. Unless you have an unusual need for small font sizes, it is unlikely that you will print any text that the 3600n can't handle. Lexmark's similar C522 sells for around Ј100 less and offers equal speed and better quality, though Lexmark's cost per page is slightly higher than HP's and the difference may add up over time.

Iggy discovers usb networking

My new laptop is fantastic, with it's nice new squeaky-clean operating system it runs like a dream. But it wasn't long before I had to face the technical challenge of getting all my old data from my old desktop computer (which was bursting at the seams with data!) onto my new laptop. I was also intending to format and give away my old computer, so I could not afford to lose any of this data in the process. I sat down at my old computer and listed all of my important files to assess exactly what and how much data I needed to transfer over to the new laptop.

Including my pictures, MP3's, Office documents, work backup's and so on, I was looking at transferring about 20 Gigabytes worth of data, it seems to build up so quickly! Thank goodness for my new laptop's 100 Gigabyte Hard Drive, which will allow me to transfer all of my data to it and still have room for a lot more. I know that the main application programmes (Word, Excel and so on) from my old computer will all have to be reinstalled on to the new laptop from their original install disks, but how do I get all the rest of the data over to the new laptop? Floppy disk?

- no way, even if my laptop had a floppy disk drive I would need about 14,000 disks! CD or DVD? - Both my new laptop and my old computer have CD ROM drives, to get all my data over using CD's I would need about 30 disks as well as some software to package all the data up nice and tidily across the 30 disks, viable but a lot of work and time needed. DVD's would be better but my old computer does not have a DVD drive! There must be an easier way. USB Memory Stick? - Not really a viable option, the maximum capacity of the USB Memory Stick that I can afford is 512MB, so this would require about 40 swaps from the old computer to the new and as my old computer is only USB1.1 which transfers at 1.5 mega bytes this process is going to be possible but really slow. Networking? - Apparently I could network my two machines together with a "Cross Wired Network lead" and a copy of "Networking Computers for Dummies", but unfortunately my old dinosaur of a computer does not have a network card! Network cards are cheap enough but I still don't want to spend any money on this old computer and really don't fancy fiddling around inside the desktop. Although it does sound good to be able to connect the two computers together and transfer the data through the cable. This is when I came across a very handy cable called a USB Data Link Cable. Apparently I can just plug one end into the USB port on my old PC and the other end into the USB port on my new laptop and then as if by magic, I should have a USB Network between both computers. Now this sounds more like it! Both my computers have USB ports and even though my old computer is USB1.1 and my new laptop is USB2.0 the cable should work anyway, although the transfer rate will only be at the lower USB1.1 speed. After finding more about this cable on the Internet I found out that it is also known as a USB File/Data Transfer Cable. Once connected, the transfer of data is done quickly and effortlessly by simply dragging and dropping files from one window to another, just as you normally would when moving files around on your system. So I ordered one online right away. The USB Data Transfer Cable arrived the next day and I got down to the business of getting the thing to work, the hardest part was working out the blatantly "translated" instructions. All I had to do was install the included software from the CD, once only on each of my computers, then plug the cable into a USB port on each computer and run the software. Two Windows Explorer type windows appeared, one showing files on the laptop and the other showing files on the PC, then I simply dragged and dropped files between the two computers. I was amazed, this USB cable solution was fantastic. It was so easy to set up and turned out to be the cheapest option by far at only Ј15 and much less hassle than any other option, almost too good to be true, magic!

Cd cleaning solution making your own

I see the kids were eating ice cream sandwiches while they dug through the DVD collection again. With kids in the house, it’s inevitable that whenever I want to listen to a CD or watch a DVD, I have to clean the discs before they will play. Luckily, I spent several years working in a CD manufacturing support group and learned the easiest way to clean discs and get them working again. Here, as simple as it may be, is my favorite solution for cleaning discs. - Mix a large amount of water with a few drops of dishwashing soap. That’s it. No expensive commercial cleaning solutions and no plastic washing devices for my discs.

I know it doesn’t sound complicated enough or mysterious enough, but it works. This solution works most of the time if you: - Use a soft cloth and wipe the solution on the disc starting from the inside hub and wiping to the outside edge of the disc. Never rub hard or in a circular motion. Don’t rub around the disc because you might scratch the disc creating an un-repairable problem. - Dry the disc with a soft dry cloth. Again, wipe the disc from the inside to the outside. Straight out. Don’t go around the disc at all because you might create scratches that are parallel with the tracks. Why does this solution work most of the time? On most CDs, and especially rented DVDs, playability problems are caused by fingerprints. Fingerprints are oil-based and the dishwasher detergent is designed to cut through and remove oil. If this method doesn’t work, you might have a disc with sever scratch or even a scratch on the label side of the disc. Scratched discs can sometimes be repaired with CD scratch removal solutions or CD repair services. Dishwasher soap and water won’t fix scratches but will make many discs playable. Copyright © 2006

Basics of rgb and cmyk for ink jet printing at home

In the world of home ink jet color printing, there is some confusion concerning CMYK color and RGB color. Many photo enthusiasts don't realize what kind of color space their digital cameras output and are confused when it comes to printing images off of their home ink jet printers. They hit print and wonder why the printed image looks different from what they see on their monitor. CMYK is the color description representing printed material, short for the colors Cyan, Magenta, Yellow, and Black. Mixing these 4 colors together in different amounts give you the millions of colors that reproduce the colors in printed material. These are actual inks used in printing the images you see in color magazines and books. RGB is the color description for images viewed on your computer monitors, short for Red, Green, and Blue.

RGB color is actually light, and mixing different levels of these light colors creates the millions of colors that come from your computer monitor. All websites and nearly everything you see on your computer monitor is RGB unless the images have been converted to the CMYK color space. When you print your images on your ink jet printer from your computer, your printer prints the image using CMYK inks. Viewing your image in RGB and then printing it out in CMYK may not yield the results you want. Programs such as Adobe Photoshop will convert your image from RGB to CMYK or vice versa. Some printers require the image to be CMYK before you can print the image correctly. Some printers don't print the image correctly if the image being printed is in RGB space. A good reason for printing with a CMYK image is to see your image in CMYK color before printing. When an image is converted to CMYK from RGB, there may be some color changes that are noticeable in the image. The reason for this is because many colors in RGB cannot be reproduced using CMYK inks. That is why it is always a good idea to convert your image to a CMYK color space before printing. You could notice significant color changes to your image, especially in the very intense color areas of your image. Some of these intense color areas may appear less intense or very dull once converted. With photo editing software, you can go in and fix these trouble color areas to your liking. Many ink jet printers on the market today actually print directly from an RGB color image. And converting the image to CMYK may cause it to print incorrectly. You will need to determine what color space your ink jet printer supports. The packaged software usually will give you a hint regarding color spaces. If there is no option to convert the color space from RGB to CMYK, most likely, the printer will print directly from an RGB color source. Usually, the higher end ink jet printers deal with the CMYK color space as consumer level enthusiasts don't even know these color spaces exist. New higher end ink jet printers, however, are now printing directly from the RGB color space as there is a wider spectrum of color that can be reproduced in RGB compared to CMYK color. If you visit the website, Instantimagers. com, the 'Framers' and 'DVD Cover & Disc Art' designs are provided in both RGB and CMYK color spaces. Comparing the RGB and CMYK images side by side, you'll notice there are color differences. This is due to some RGB colors not being available as a CMYK converted color. Both versions are provided because not all printers are alike. Some tend to print better with one color space. Many of CMYK printed designs have been manipulated further after conversion to match more closely the colors from the RGB color space as many of the colors in some designs did not covert seamlessly. If all this seems confusing, not to worry. The key thing to remember is to print using RGB color if your printer and software support it. Let the software and the printer worry about getting the colors right. If you are more experienced with photo color correction and want more control over the color of the image, print in CMYK. You'll actually be manipulating and printing the image in the color space your ink jet printer's inks are using. You will be able to see the limits of the CMYK printing color spectrum right on your monitor. Getting color right with RGB and CMYK is totally different from calibrating your printer to match the colors on your monitor. That is actually the second step in getting the best color out of your prints. Understanding the difference between RGB and CMYK is the first step in getting the best print outs on your home ink jet printer.

Cartridges

“Cartridge” refers to a detachable sub-unit that is held within its own container. They were popularized by early home computers like Commodore 64 and early TV games systems. The advantage of cartridges lies in the fact that they facilitate quick loading of software from one media format to another. It also helps maintain the software in a sturdy and damage-resistant form. Throughout the 80s and the 90s, all home video game systems were cartridge-based. As technological advancements in the late 90s ushered in CD technology as a cheaper alternative for data storage, hardware companies shifted from cartridges to CD-based game systems. This was on account of the lower costs and larger storage space provided by a CD-ROM. Now, cartridges are most commonly used in printers. They are encased in a larger container, which has both inlet and outlet ports that contain around 13500 fibers and 16KB of space for storing table of contents and file-location information. Each cartridge can store about 25MB of uncompressed data. There are several types of cartridges, including inkjet cartridges, laser cartridges and toner cartridges. These cartridges come pre-filled with ink, though there are some innovative cartridges that are refillable on the market as well – these are called remanufactured cartridges. Remanufactured cartridges of all types are abundant so care should be taken to ensure that the job of refilling them has been done safely and problem. The most common problem with remanufactured cartridges is they can be prone to leakage, especially if not filled correctly. If remanufactured cartridges are leaking inside the foil pack, then they should be returned to the place of purchase.

Perpendicular hard disk drive

: What is a Hard Disk Drive? A Hard Disk Drive (HDD) is a device used by modern computers to permanently store information. The Hard Disk Drive is arguable the most essential part of a computer system in that all the information that is permanently stored is contained within its enclosure, including your computer’s Operating System (OS). Thanks to Hard Disk Drives, long gone are the days when you would have had to keep all your programs and documents stored on removable media such as Floppy Disks or CD-ROMs. Originally invented in the mid 1950’s and made commercially available in 1956 by International Business Machines (IBM). Called RAMAC (Random Access Method of Accounting and Control), the first Hard Disk Drives contained as much as 50 platters which were 24 inches in diameter and were computers in their own right albeit with a single purpose – to store data. The entire unit which housed the hard drive was the approximate size of two large refrigerators placed side by side. In the 50 or so years since their invention, Hard Disk Drives have steadily and aggressively far out paced Moore’s law. Which stipulates that memory in computers will increase by 100% approximately every 18 months. Hard Disk Drives on the other hand have increased capacity in the same period by approximately 130%, an increase of 100% every nine months in many cases. Such capacity increases are being threatened, however. In the years since the first Hard Disk Drive very little has changed apart from logical steps in technology such as the increased speed or improved interfaces, the basic technology has changed very little. There have been no technological leaps, as it were, for Hard Disk Drives beyond their increased miniaturisation.

Apart from miniaturisation and recording media improvements the Hard Disk Drive as a device is almost identical technologically speaking, to the very first, the RAMAC. Hard Disk Drives use a similar technology as is employed in audio and video cassettes. Such audio and video cassettes use a magnetic ribbon wound around a two wheels to store data. To access a particular portion of the data contained on the magnetic ribbon, the device must wind the tape such that the beginning of the section containing the data is underneath the device that reads the data (the magnetic read/write head). This process is called sequential data retrieval because in the process of accessing the particular data, the device must sequentially read each piece of data until the data it’s looking for is found. This process is very time consuming and contributes to wear.

Hard Disks on the other hand use a circular disk-shaped platter upon which the magnetically sensitive compound is laid. Such platters are similar in concept to a Compact Disk (CD) in that the data they hold can be accessed randomly, that the recordable media is in a circular (disk) shape, and that the data is sectioned off into tracks and sectors. Data on a Hard Disk Drive can be accessed randomly because the recordable medium of Hard Disk Drives uses these separated tracks and sectors. By separating the data in such a way, it can be positioned at random intervals of the disk, depending upon the space requirements. Anywhere from one to seven recordable platters are contained within a modern Hard Disk Drive’s metallic enclosure. Hard Disk Drive platters are perfectly circular disks made from either an aluminium alloy or a more recently a glass ceramic substrate which is a ceramic disk suspended in a glass outer shell. Onto the surfaces of a disk’s platter is laid a thin layer of a magnetically sensitive coating called the recording medium, in modern drives the mixture is a complex amalgam of different materials such as cobalt chromium platinum boron (CoCrPtB) and other such rare metals.

How does a Hard Disk Drive store data? All information located on a computer is expressed as a series of ones and zeros (1/0), as binary digits (bits). Taking advantage of the nature of magnetic particles, that they can be polarised to magnetic north or south and that their magnetic poles can be alternated or switched when a sufficient magnetic field of the correct polarity is applied, Hard Disk Drives can store the very same sequence of bits onto a disk by polarising the required magnetic particles on the recording medium such that they represent the data being stored. Hard Disk Drives are sectioned off such that they contain both intersecting tracks and sectors. The purpose of which is to provide a logical data structure, to provide a way to distinguish between areas of data. Within each track there are a number of sectors.

It is within these sectors of the Hard Disk which data is stored. The platter of a Hard Disk Drive is coated with a magnetically sensitive coating comprised primarily of magnetically charged particles or filings which as a whole may be called the recording medium. These particulates can be magnetically aligned such that they represent binary digits, by inducing an electromagnetic field upon them via a devices read/write head. The recording media contains many billions of microscopic particles which when viewed extremely close resemble miniature metal filings.

When a Hard Disk Drive records data onto the medium it takes many hundreds (usually anywhere from 500 to 100) of these magnetically sensitive particles to store a single binary digit. The increased reduction of the amount of particles required to record data is highly limited by the precision of the read/write head (the miniature device that reads and records data onto the recording medium) because the magnetic field which is used by the drive’s read/write head to read and/or record (write) data is such that it already tentatively borders nearby data. Should it be shrunk much further in an attempt to increase precision, the likelihood of data corruption would increase vastly. Research by various parties has been on-going to find a workable solution to recording data onto much fewer or even single particles for some time now. A hard drive may record data onto the Hard Disk Drive by applying a sufficient magnetic field to the section of the recording medium (which is suspended upon the Hard Disks platter) such that the data (a series of ones and/or zeros which correspond to the information being stored) is recorded onto the medium by aligning the specified particles to the desired magnetic pole (north or south). In doing so, any previous data which was present is therefore destroyed. Perpendicular verses Longitudinal Ever since the late 1980’s and early 1990’s magnetic media drive manufacturers have been researching the feasibility of switching from longitudinal to perpendicular recording techniques.

The advantage is clearly one of capacity: when longitudinal magnetic particles are packed together, they take up much more space than if they were to stand upright, if they stood perpendicular to the platter. More than merely a matter of initial capacity gain, perpendicular recording technology avoids a problem which has been well known in the field for many years: the super-paramagnetic effect (SPE), which affects magnetically charged particles of such small size as that used in Hard Disk Drives. “The super-paramagnetic effect is a phenomenon observed in very fine particles, where the energy required to change the direction of the magnetic moment of a particle is comparable to the ambient thermal energy” (source: Wikipedia. org).Many theories have cropped up over the years as to what density magnetic particles (described by a disks areal density) may achieve before becoming subject to SPE. At present it is suggested that anything from 100Gbit/inch2 to 150Gbit/inch2 is the physical limitation for longitudinal Hard Disk Drives, although perpendicular media solutions have been made as high as 230Gbit/inch2. In the layering of the magnetic particulates atop a magnetic suspension layer and orienting the particles perpendicular to the platter, the recording medium can pack many more magnetically sensitive particles together in the same space than previously possible whilst keeping SPE at bay. Perpendicular recording technology does not however preclude SPE from limiting capacity in the future, more than anything perpendicular recording technology can been described as a way to give manufacturers breathing room to develop more permanent technological solutions such as holographic lithography or a multilayered recording medium. Traditional recording media manufacture consists of the spreading of recording material over a disk platter via a centrifugal force induced by spinning the platter whilst the recording material is placed atop its surface.

The centrifugal force would spread the recording material across the surface, evenly spreading it in all directions. Perpendicular recording media manufacture on the other hand requires a much different technique. The exact manufacturing process of perpendicular recording media is unsurprisingly a closely guarded secret, especially considering its recent arrival on the marketplace. From patents filed at the United States Patent and Trademark Office (USPTO), it can be taken that the predominant technique involves the laminating of magnetic and non-magnetically charged metals such as chromium, cobalt, platinum and alloys of similar; sandwiching unique layers to affect the desired result – a recording medium such that the magnetic particles are aligned perpendicular to the platter.

In US patent number 6387483, filed by the NEC Corporation of Tokyo; it describes the technique as follows:The perpendicular magnetic recording medium of the embodiment is formed by laminating a Cr film, a soft magnetic under layer film, and a perpendicular magnetizing film on a substrate in this order. (Source: USPTO no. 6387483) In longitudinal media manufacture too, laminating multiple supportive metals is achieved; in perpendicular media however, the difference is the magnetizing film as described above. Whereas traditional lamination ordinarily serves only to prevent wear and noise (both electro-mechanical and audible noise), in perpendicular media manufacture it would appear that at least some of the lamination process is used to magnetize the magnetic media particles to a perpendicular orientation. Precisely how the reorientation of magnetic media particulate is accomplished is not easy to determine, most probably because the technology is so new that such details are sketchy at best and obscure or guarded at worst. This fact is not at all surprising concerning a new technology such as perpendicular magnetic media development.

The future of storage technology Perpendicular magnetic media technology as discussed earlier is merely a temporary solution, to find more permanent solutions we must look to much more advanced technologies. One such technology is patterned magnetic media. The process of patterned magnetic media aims to make singular magnetic particulates the object of recording bits, you will remember that current technologies requires approximately 500 to 1000 magnetic particles to store a single bit. The object of patterned media is to cut this dramatically down to a single particle per bit. Advantages of such a technology are such as reduced statistical noise associated with granular media and more increased areal density (as much as 64Gbit/inch2). Patterned magnetic media aims to prevent the SPE barrier, or at least further decrement its effect through the use of so-called mesas and valleys. The technique uses the creation of barriers between magnetic particles, thereby avoiding the SPE complication which affects closely packed particles. Holographic Storage (a. k.a. Holographic Lithography) too is a technology that aims to increase storage capacity which is also under heavy research, and claims to be a much more permanent solution.

Unlike Patterned Magnetic Media, Holographic Storage is a revolutionary step away from magnetic media and previous optoelectronic technologies. Hard Disk Drives will always be subject to inertia and centrifugal force induced by the moving parts of the drives mechanical components (platter, read/write head), Holographic Storage has no such issues; the holographic process uses lasers in replacement of the read/write head of a Hard Disk Drive and the media itself requires no momentum (unlike the platters in Hard Disk Drives). Such holographic storage is far from realisation, in fact it is postulated by some that it may be as much as ten years before the technology can be made into a workable solution. In direct symmetry to early memory research, research on Holographic Storage technologies seems to have banded into two camps: one of super fast data retrieval and extraordinarily high capacity storage; no doubt there will be extremely profitable markets for both.

Which laptop battery is right for you

The short answer is: “Whichever type fits your laptop.” Laptop batteries vary according to the model and type of laptop computer for which they’ve been designed. All laptop batteries do, however, share some common characteristics that differentiate them from regular household batteries: • Laptop batteries are rechargeable • They are composed of multiple internal cells • Within each laptop battery is a small printed circuit board • Shape and location of terminals differ from model to model. As is the case with all batteries, laptop batteries create an electrochemical reaction, forcing a stream of electrons from one position to another. Also like other batteries, laptop batteries have positive and negative terminals that receive and send electrons. Rechargeable batteries are more complex, however, than standard batteries. This is because the electrochemical reaction that provides power must be reversible. Care has to be taken when recharging them to ensure they perform at their best. Frank McLarnon, Lawrence Berkley lab’s staff scientist explains it this way to Scientific American. com: "When a battery is discharged, an electrochemical oxidation reaction proceeds at the negative electrode, and an electrochemical reduction reaction occurs at the positive electrode. When one attempts to recharge a battery by reversing the direction of electric current flow, the opposite takes place: a reduction reaction proceeds at the negative electrode, and an oxidation reaction takes place at the positive electrode. In the case of the rechargeable battery, the electrochemical oxidation-reduction reactions are reversible at both electrodes. In the case of the non-rechargeable battery, when one attempts to recharge the battery by reversing the direction of electron current flow, at least one of the electrochemical oxidation-reduction reactions is not reversible. When the battery is charged, the overall reduction reaction that proceeds at the negative electrode may not be the true reverse of the oxidation reaction that proceeded when the battery was discharged. If the laptop battery process isn't exact, then unwanted build up can take place on either terminal over time, which can cause a dangerous short-circuit.” It is so important to ensure that your laptop battery or notebook battery is the one designed for your particular model and type. Only buy Dell laptop batteries for a Dell laptop computer, Gateway aren’t compatible with Compaq laptop batteries and Toshiba laptop batteries won’t sit well in a Sony. It is also wise to remember that old adage: “You get what you pay for.” Some companies offer used “cheap laptop batteries” for sale, saying that they have refurbished each battery and restored most of its useful life. The fallacy of this is that, although possible to refurbish a second-hand laptop battery, the cost to do so would be more than the price of a new battery. So, “Buyer beware,” and if you must buy discount laptop batteries, buy new discounted batteries. Laptop computers are a boon to business, large and small. As a wise person is just about to say: “Look after your laptop and it will look after you.”

Beginners guide to buying a pda

Are you considering the purchase of your very first PDA? If so, what should you look for? How much should you spend? What features should you get? Before making the final decision to purchase a PDA, have you thoroughly researched what they can do, and if you really need one or are you just intrigued by having a new gadget like your friends? Let’s start with this question. One of the first and still major uses for a PDA is an appointment book or calendar. If you are currently using an appointment book like a Franklin Planner, the PDA can certainly replace this. One advantage of a PDA over an appointment book is that changes don’t require constant erasing and re-writing. A PDA is usually backed up on your PC, so there is always a back-up. A new PDA does not have to be purchased every year like a Franklin Planner, so in the long run it will be cheaper. This plus the previous mentioned advantages may be enough to make the switch. Of course there are many other features and uses for a PDA besides an appointment book, among which are: • Address book • Calculator • Internet Access • Notes and document management • Games • GPS Given that you are ready to go forward with the purchase, your choice of a PDA model will depend on what you need it for—what you want it to do. Following are some of the important considerations: Memory – If you plan to use your PDA for storing large documents and other reference works, then you’ll need the corresponding amount of memory. Also check to see if the memory can be expanded. You’ll need to consider the other software that you might want to run on your PDA. Size – All the features do you no good if you don’t bother to bring the PDA with you due to its bulky size. Input Options – If you plan on using the PDA to take notes with, a compact external keyboard is essential. The built in stylus input is designed for small amounts of data only. Battery Life – Again, dictated by your specific needs. Finding the best place to purchase your PDA can be done easily with online shopping portals. Ebay of course always has offers. One thing to consider for a PDA is a buyers protection plan that is offered by many local retailers. Normally these end up costing more than they are worth, but just one drop of your PDA onto a hard surface can destroy it. If you are buying a high end PDA and will be running around with it daily, a buyers protection plan may be worthwhile.

Take your laptop for a walk on the wireless side

Wireless internet access is truly the wave of the future and depending on where you live the future could be now. Wireless "hotspots" really are popping up somewhere on a daily basis. Not that I'm complaining, because having the ability to access the internet via a wireless connection is a great convenience and allows you to "Take Your Laptop For a Walk on Wireless Side". On the other hand, even though there are thousands of "hotspots", they don't always get a whole bunch of publicity. However, if you were to do a search for "hotspots" in your town you may be pleasantly surprised. You may have thought that there weren't any in your area but if you live in even an average-size city then it would be more of a surprise if you didn't find a few "hotspots". Another alternative would, of course, to do a search for "hotspots" or "wireless hotspots". There are a ton of websites you can go to and find "hotspots".

One "hotspot" that is generally considered to be on the most comprehensive is jiwire. com. You can search for local "hotspots" from the JiWire website or could simply type your zip code into Yahoo Maps and choose 'WiFi Hotspots' from the menu located on the right side of the screen. Another option would be to check out the nearest Starbucks. They are literally everywhere and almost all of them offer wireless internet access in at some part of the store.

Borders and Kinko's are also pretty good bets and if all else fails... keep a watchful eye out for a local cafe or simply ask around a little bit and someone should be able to point you in the right direction. Small Wireless ISP Fee You may find that some of the larger hotspot networks with multiple, convenient locations require that you pay a small fee to a wireless ISP to access through them. In many instances, you can simply purchase a prepaid card at the place where the access is offered so it's really not a big deal. However, if you want to free access your best bet would be to stick to the smaller independent locations. Why Would a Cafe Offer Free Wireless Internet? Actually, if you think about it, it's really nothing more than good business. Rather than pay to access the internet in some dingy Internet cafe, you can access the Internet for free in their place of business and while there buy their food and drinks. Cafes are willing to pay the minimal cost of providing wireless Internet access in exchange for the new customers it brings into their business. Especially, in areas where Internet access is hard to come by, any other way. The same goes for hotels and airports: customers see wireless access as an added value and in many instances; they will choose a particular hotel based on this feature alone. Actually, the real growth area in wireless "hotspots" is in the private sector. Businesses are falling all over themselves to provide free Internet access to their business customers - cafes, hotels and airports are all starting to offer wireless access to anyone who happens to be around. All you need to do is bring in your laptop with Centrino technology or a wireless PCMCIA card. We've already covered a number of potential public hotspots to take your laptop and go searching for but one that hasn't been mentioned is in reality may be one of first places to check out is your local public library. Public and university campus libraries are increasingly offering wireless access and if you're a student there's a good chance that your whole university campus is wireless enabled - or will be soon. Hotspot Locator Software Hotspot Locator Software allows you to create a database of known "hotspots" on your computer that you can search at any time, whether you are online or offline. Simple type in a zip code or the name of a city and the software will come back with the nearest "hotspots"... all sorted by distance from your location. And to make sure that your database doesn't get out of date, each time you access the Internet the software automatically connects to its servers and checks the latest hotspot to your list and if your list if out of date it will download and update your list with the latest information. If hotspot locator software sounds like something you'd like to take for spin, you're in luck because it's offered for free from many of hotspot providers' websites.

Guide to buying a laptop computer

With the many different brands and models on the market, buying a laptop or notebook computer may at first seem confusing. But simply breaking down the process into a few key areas and using Myshopping. com. au to search for the most suitable features and pricing makes it much easier to access exactly the machine you're looking for. How important to you is mobility? Mobility in laptop computers is a combination of size, weight and battery life: how often you carry it around, and if you will be relying mainly on the notebook's battery, or whether you will access an external power source. Laptops can weigh from a little over 1 kg up to 6kg, depending on the model and features included. The screen, storage space and disc drive all affect the weight. Battery life is shortened by bigger screens and multiple disc drives. Manufacturers advertise the weight of the laptop in their specifications, but it is important to consider whether that specification includes batteries and other peripherals such as external drives that you may be lugging around. The most common battery type is Lithium Ion (Li-Ion), which can operate for one to three hours under normal working conditions. But many power saving options available and higher celled batteries can extend the discharge time considerably. Battery life deteriorates over time however, and as your laptop ages; the discharge rate of the battery will diminish. Sometimes it is worthwhile carrying an additional battery. Application and cost If mobility is of a lesser concern, then battery life and weight will be less important. You may be more inclined to have a bigger processor, screen size and memory capacity. The type of work you do can affect the screen size and type that is most suitable for you. For a lighter load, and less graphics intensive applications a 12-14in screen instead of 15 or 17in widescreen will be more suitable. If, on the other hand, the graphics capabilities and size of the screen are important then the best screen you can afford will be more of a priority. It may work out cheaper to buy a basic unit and add such things as an external TV card and DVD burner when the need arises. How much you need to spend is closely related to how you use your laptop. If you only want to access your e-mail, browse the Web and do word processing, then you can consider lower budget machines with smaller processors, screens and facilities. A medium-level user, perhaps playing games or working in multimedia applications, will need a powerful processor, graphics controller, storage space, and a bigger screen. The more features your laptop has, the more expensive it will be. Including a DVD-burner instead of DVD-ROM, hard drive capacity of more than 40GB, a 17in widescreen screen and wireless capabilities results in a more expensive machine. If you are not looking for high power and graphics capabilities, then you may find a suitable laptop for around $1500. The latest processor, full blown graphics capability, DVD burner, widescreen and wireless connectivity may cost over $4000. Use Myshopping. com. au to search with different price ranges. Other key components Having determined by what you will do with it, and how mobile you need to be that you are definitely buying a laptop, you now need to get down to the nitty gritty and find the specifications that will meet your needs. So, what to look for? Essentially, you are considering differences between the following components: display, graphics controller, memory (RAM), hard disk, removable storage, networking options, peripheral connectivity, sound and battery. Display and Graphics Notebooks now all feature LCD screens (Liquid Crystal Displays) presenting crisp text and reduced eyestrain. These screens display sharper text than standard CRT monitors, but are less capable of displaying well-rendered graphics. If you will be using your notebook for graphics work, it may be worthwhile having a CRT monitor to connect to. Screen sizes for notebooks range from 12.1in to 17in (widescreen). A 15in display or 15.4in widescreen alternative is the most common in notebooks today. Widescreen is quickly becoming more common, partly to accommodate playback of DVDs and also because widescreen proportions make it is more durable. On-screen graphics are affected by both the size and type of screen as well as the graphics card. It is reasonably safe to assume that larger displays offer higher on-screen resolution. Screen brightness (measured in nits) is another specification that can vary between makes and models. Brighter screens impact less on eyes and can be more easily read in bright conditions. Some manufacturers have a glossy, reflective coating over the display improving contrast and colours. But, because it increases the reflectivity of the screen, it can show you reflected in the screen. Surface scratches may also show up more readily. Not all LCD screens have the same viewable angle, with some screens not easily viewed from a side angle. Graphics performance in laptops is still inferior to that of desktop machines. All graphic controllers easily render 2-D images and if you don't need more from your graphics, then an integrated graphics controller is ample. However, if you want to play the latest 3-D games at a decent resolution and frame rate or you're a CAD designer, then you'll need a discreet graphics controller with a dedicated DDR video memory. Memory and Storage In all computers RAM chips keep the CPU efficiently fed with data or instructions from programs on the hard drive. Notebook computers now commonly use DDR SDRAM (Double Date Rate SDRAM), the default standard, and DDR2 SDRAM which is a next-generation memory type offering considerable performance and power benefits over SDRAM. Either way, when it comes to RAM, more memory is better and you should consider 256MB as the absolute minimum. Upgrading memory can achieve better performance, and quite a number of vendors offer higher RAM configurations as a 'deal sweetener' at the time of purchase. Search through Myshopping. com. au for bundled extras such as more RAM. The hard drive provides the long-term storage and is the centre of program control. There are two critical specifications of hard disks. One is disk speed, measured in revolutions per minute (rpm). Faster disks speeds provide quicker access for loading and saving and 'file swapping'. The other is storage capacity, and drives are now available for notebook computers with 120GB capacity. If you work with large file sizes, then you will probably want at least 40GB of hard drive space. You may also want to consider the type of removable storage such as a DVD writer, removable hard disks and media or 'flash' card systems that will suit your use best. Networking and connectivity Laptop computers now include 56Kbps modem (RJ-11) and 10/100 Ethernet (RJ-45) connections as standard features. Some feature an Infrared port and you can use it to connect your mobile phone. Other wireless technology for connecting mobile phones, printers and PDA devices includes Bluetooth and Wi-Fi, allowing connection at certified public access points and home wireless networking. Most laptops use USB 2.0 or FireWire connection for connecting keyboard, mouse, printers, cameras and other peripherals. Nearly every new notebook will have around three USB 2.0 ports, and one FireWire port and a VGA-out port to connect an external monitor to. Notebook computers have traditionally been able to expand their capability through simple plug-in PC Cards. Recently a new standard has emerged called ExpressCard, a smaller, faster and more portable plug-in card to provide such things as expanded video and sound capacity. Choosing a laptop becomes much easier once you've decided on these basic requirements. You can search Myshopping. com. au to compare makes, models, prices, accessories and all the important specifications. You can also compare vendors and their prices and service.

What to do when your keyboard fail

Do you think the keyboard is important? Try using your computer without it. Your computer will be almost useless without the keyboard. And like all other PC peripherals, the keyboard can and will put you down. The keyboard is a simple peripheral and when it does go on the blink, you will be much better off pyrchasing a new one rather than considering repairing it, unless the problem is something simple like a stuck key. TROUBLESHOOTING BASICS As we look into problems with the keyboard, remember the check the obvious first and as with all problem solving procedures, don't be tempted to take shortcuts. Follow these procedures to resolve common keyboard problems. KEYBOARD WILL NOT RESPOND 1st. Restart the computer. This sometimes will resolve a computer that has froze or locked up during the first boot up. 2rd. Look behind the system unit and check to see if the cable is fully inserted into the connector. Check to see if it is in the keyboard connector and not the mouse connector. Shut the computer off and remove the cable from the system unit. Check to see if any pins or connectors have been bent or broken. If all pins and connectors are good. Try connecting another keyboard and restart the computer. If the new keyboard works, replace the old keyboard. CHECK FOR KEYBOARD ERROR IN WINDOWS If the new keyboard should fail as well, check the resource conflicts if your operating system is Windows 98 or Me. Click on Start, Settings, Control Panel, System, and Device Manager Tab in System Properties. Windows displays your devices attached to your PC. Click the plus sign and scan the list for the keyboard. If you notice an exclamation point or a red X beside the keyboard, the keyboard has a problem. Now highlight the keyboard, click the remove button, and click OK in the confirmation window. Close the Device Manager and restart the computer. The operating system will reconfigure the keyboard. WINDOWS DID NOT FIX THE KEYBOARD You have restarted the computer and the keyboard still does not work. Its now possible you have a faulty keyboard port. This may prove true if the second keyboard failed to work on your computer as well. Though it rarely happens, an error message will appear if the keyboard get hot. Stuck keys are also causes of error messages appearing on your monitor at bootup. POOR KEYBOARD PERFORMANCE Keeping the keyboard free from dirt and dust, is essential to good keyboard performance. Liquid spills are common and can be cleaned with a can of compressed air. Your settings in Windows may also be the culprit in poor keyboard performance. To check your keyboard performance, click on Start, Settings, Control Panel, and double click keyboard. On the Speed Tab, you have the option to control the Repeat Delay, Repeat Rate, and the Cursor Blink rate. The Repeat Delay is the delay between the time you press a key and when it responds. The Repeat Rate controls just how fast the key repeats after it begins repeating. Windows give you the ability to control features of your keyboard which will boost its performance, allowing you to perform your tasks quicker. While the keyboard is replaced rather than repaired, it is imperative that you learn troubleshooting steps to correct most keyboard problems. You may have problems with the keyboard late at night and you may need to get it working to complete a document you may need for work. Know how to correct problems and help others that may experience keyboard failure.

Laptop screen inverter

The small piece of circuit board, which is usually located underneath the plastic shell of your laptop’s screen casing, is probably the cause of one of the most common problems related to screen failure and, more specifically, dimness, or darkness to the screen itself. The main purpose of the inverter is basically to give power to the backlight. The way it works is simple, it takes power from the laptop itself by a small inverter lead that runs from the motherboard of the laptop, sometimes it is a direct lead on it’s own, other times this lead can be connected into the inverter through the LCD cable (the lead that runs from the motherboard to the back of the screen itself), giving the screen its visual display. At one end of the inverter, usually the left end, the lead that gives it power is plugged into a small white socket and from the other end, usually the right side, the backlight lead from the screen is plugged into another white socket. The backlight is a very small, thin, long, very delicate light bulb that runs along the very bottom or sometimes the side of the screen.

The problems related to the inverter is dimness or darkness to the screen in most cases or flickering of the backlight. Sometimes it can stop the screen form working at all but not usually. A common fault with laptop screens is a dark or dim screen, generally it is assumed that it is the backlight that is at fault, sometimes this may be correct, however more often or not it is simply the inverter not working, or not giving the backlight the power it needs. The inverter is usually cheaper to replace than the backlight, as the backlight is very fragile and can be easily broken.

On some occasions a repair of the inverter is possible, although usually labour charges on fixing the inverter can sometimes lead up to being more expensive than simply replacing it. When it comes to purchasing an inverter most companies will require the part number which is usually printed on a bar code on the outside of the inverter but sometimes you may need to look carefully to find it. If your lucky then you may get away with just stating what your laptop make and model is, for example ‘I have an IBM Thinkpad T22 and I need an inverter’, we try our hardest to locate the inverter with just these details, however sometimes you will need to provide the part number; here is an example of a part number from the inverter for an IBM Thinkpad T22, (10L1402). This inverter is also compatible with the IBM T21, and T20 all three laptops as a whole are basically the same apart from the processor.

A checklist for used computers

It is very important to check a used computer thoroughly before buying it as it may lead to problems in the future. A hard drive will not show any outward signs but may be deteriorating. The same way the needle can suddenly slip and can cause scratches on the disc ultimately leading to memory loss as used computers can fail any time. If they are checked, the faults which may occur can be known. Let us first see the possible faults which may occur while purchasing a used computer. Hard disk failures can happen due to heavy wear and tear over a period of time. The read and write heads of a hard disk are used to retrieve or recode data stored on the hard disk with the help of a disk platter rotating at a high speed. Over a period of time the risk of failure or malfunction of disk increases. Faulty sectors of the hard disks can be found out only if a full surface scan is done on the used computer. The scanning time depends on the capacity and size of the hard disk of the used computer.

Many skip this procedure due to the time consuming process of scanning the whole disk and end up purchasing a used computer with a faulty sector. Monitors need to be checked for any faults. The malfunctioning of a monitor is called a “dry joint” which results in the monitor not working after getting warmed. This can be checked only if the monitor is made to work for at least 20 to 30 minutes after switching on the computer. Next is to look for any possibilities of the central processing unit getting freezed. Normally all the central processing units have a fan and heat sink for keeping the unit cool.

Over a period of time the fans may not work properly due to the accumulation of dust and dirt resulting in over heating of the central processing unit and even leading to stopping from functioning. While buying a used computer the fan needs to be checked and if any abnormal sound is heard, it is not good for purchase. The used computer may have a higher possibility of getting crashed and freezed due to the usage of the operating system for a good number of years. There may be a cache or RAM fault due to the over exposure leading to loss of data. To increase the performance of the computer and to avoid crashing, the operating system of the used computer can be reinstalled with a new operating system or a fresh one. While checking the used computers for any faults, it is good to disconnect the network connection if any present before performing the tests. Also it is advisable to check the drives like the CD or DVD by opening and closing them and also playing something on the drives to see how they work. Monitors of the used computers can be checked for the resolution and brightness by trying different options of color, settings and so on. To check the hard disk size the CMOS setup can be gone through and to verify the speed of the processor, cache and RAM the pause button is pressed when it appears on the screen during the booting process. To check the booting process, the computer can be turned on and off a few times and seen how it responds. Checking should be done to see if all the passwords are erased before purchasing a used computer.

Epson yesterday and today

Epson started as watch making company Seiko Epson Corporation, Japan. Epson was established in 1961 to manufacture precision parts for Seiko watches, back then it was called Shinsu Precision Manufacturing Company. Epson’s first foray into the printing and imaging business was the Olympics of 1964 held in Tokyo. The company was awarded a contract to develop a precision timer for the Games. The printer they developed for the Olympics - EP101 is also, where Epson derives its name!

It was one of the first printers for electronic calculators to hit the commercial market. It was the beginning of Epson’s journey in the printing and imaging business. The TX-80, Epson’s first dot matrix printer hit the market in 1978, then in 1984 came the SQ 2000 it’s first inkjet printer. The TM 930 Epson’s pc-pos package printer launched in 1990 created a new market in the printing business. Epson gave a number of first printers to the world among which is Epson stylus 800- an inkjet printer equipped with micro peizo technology launched in March 1993, and then the Epson Stylus Color in May 1994 was the world’s first 720 dpi color inkjet printer. September 1998 saw the launch of TM-H5000 its first hybrid printer which featured fast quiet printing and copy functionality. Epson’s Technological Breakthrough The Ultrachrome K3 Ink The Epson UltraChrome K3 Ink is a high-density resin coated pigment ink. It comes in two types Black & White and Color. It has a wide color gamut for both types. The black palette consists of three shades of black - Black, light black and light light black. The color palette consists of the standard cyan, light cyan, magenta, light magenta and yellow. Oh and it has two user exchangeable black ink modes - photo and matte! Now you will wonder what is so special about Ultrachrome K3. A simple comparison between the traditional toner manufacturing process and the ultrachrome K3 process will answer the question - traditional toners were manufactured by grinding the toner particles mechanically to the smallest possible particle size that can be achieved mechanically; now the major disadvantage here is the energy and hence cost. You would wonder how energy comes into picture. The process being mechanical and done under pressure requires considerable amount of energy and the smaller the particle size the more energy required and energy is expensive! The second disadvantage is that the particle size is not uniform and cannot be controlled, again because the process is mechanical put simply a grinding process! Both of the above disadvantages are overcome in the Ultrachrome K3 manufacturing process. The process is chemical process requiring negligible energy. The resin is placed in a water-based environment where the particles are allowed to grow in a controlled environment. Once the particles have achieved the desired size, they are removed from the environment and processed to give the Ultrachrome K3 ink! Sounds simple right? However, the process is not as simple as it sounds! The Customer’s Advantages: Energy and cost conservation are the Epson’s advantages; what benefits do the customers get. At the end of the day, the customers have to be very satisfied, if they are going to buy “the system”. 8-Color Ink System * High Density pigments for an extremely wide color gamut * Professional print permanence ratings for truly sellable quality prints * High-gloss Microcrystal Encapsulation Technology for reduced gloss differential * Superior scratch resistance from improved pigment and resin chemistry * Color is stable immediately after printing - no short term color shifting Three-Level Black Ink Technology * Simultaneously uses Black, Light Black, and Light Light Black inks * Significantly improves the printers gray balance * Impressive midtones and highlights for a smoother tonal range Two User-Exchangeable Black Ink Modes Two specific black ink modes - Photo Black or Matte Black Optimizes black ink density for various media types dramatically improving the final print quality It is goes without saying that Epson like all other top brands in the market too encourages its customers to use only original Epson ink and Epson media to achieve best results. It claims that the ink and media are manufactured to work hand in hand to achieve the best results as compared to their competitors!

Find your laptop drivers easily

Many people, especially beginners, struggle in finding drivers for their laptops. In this article, I will illustrate two ways to help you find your laptop drivers quickly, and easily. The first method we will consider is to visit a company's website, and attempt to find a 'Drivers' or 'downloads' link. If a similar link is not immediately apparent, look for a search box. Most laptop companies have a search box somewhere on the homepage of their website. Type the model number of your laptop into the search box and click search. Typically, you will be sent to an overview of the model you have entered.

Look for 'Downloads' or 'Drivers' links. Hopefully, if this link is available, you can follow it to find the necessary drivers for your laptop. For example, say you have a Dell Latitude D600 laptop, for which you wish to locate updated drivers. The first step is to visit Dell's website.

From the first page, click on the 'Drivers and Downloads' section. After clicking on the 'Drivers and Downloads' link, we choose the required model. In our example, it is Latitude. Then we enter the model number (D600), followed by selecting our operating system. The Dell website will show a list of available drivers and software updates for your model. Select the driver you wish, and click 'Download'.

What if you do not know the website of your laptop's manufacturer? Or, perhaps when visiting the website, you couldn't find the 'Downloads and Drivers' section? A second method for locating laptop drivers would be to visit Google ( google. com), and entering, "Download (manufacturer) (model name and number) [type] driver" or "[type] driver for (manufacturer) (model name or number)" into the query box, substituting your own manufacturer, model name and number. For example, if we wished to find the sound card for a Dell Latitude D600 laptop, we could go to Google. We would enter either of the following queries: -"Download Dell Latitude D600 soundcard Drivers" -"soundcard driver for Dell Latitude D600" The driver download page for you laptop should appear near the top of the results returned by Google. Follow the link to the driver page, and proceed to download the drivers you need. These two methods should make it easy to locate the drivers you need for your laptop. Good Luck!

Evaluating a used computer

Used computers are available plenty in number. But, the prime concern is that how it will satisfy the needs of the purchaser. The next one is about the functionality of the used computer and the longevity of the computer parts of the used computer. Many people decide to purchase used computers due to a tight budget, but they should not end up buying a showpiece rather than a working piece. This makes it very important to evaluate the used computer before buying it. Evaluation can be done by the purchaser himself provided he has some knowledge on computers and their parts. If not, he can get some help from their friends or relatives who are good in evaluating computers. The used computer’s physical parts should be inspected thoroughly. First step is to look for any damages and then trying to turn on and off. It should be done by the buyer or by his friend rather than watching the computer sales person do it as it will alert for any glitches. Checking needs to be done to find out if the used computer has an original version of the operating software without which the computer is not worth buying. Manuals, licenses for software applications, discs and fonts should be got along with the computer.

The operating system of the used computer should be compatible enough to run the required applications of the buyer. Some times the seller may sell a used computer along with used disk drives, scanners and printers and include the cost of them too. It is not wise to buy used scanner, printers or disk drives as they have peripherals with moving parts which wear and tear with the passage of time and also the cost of them can be deducted making the price of the used computer even lesser. The speed of the central processing unit needs to be checked. If it is not up to the expectation of the buyer, it needs to be found out if the used computer system can be upgraded for improving the speed and functionality. The entire hardware components should be checked including the keyboard, speakers, monitor, mouse and microphones. It should be if all the hardware components inside the computer like the CD-ROM drive, sound card, number of RAM sockets etc are if present or not and if present what are the components in use. Also it needs to be checked whether it has a provision for adding different type of cards etc. If the purchaser has already got some computer components like the monitor, printer and so on, the used computer which is bought should be compatible with them. Nowadays used Pentium machines and power PCs are available at very low price. It is not advised to buy a used computer which is very old. Also it is good to find out if the used computer comes with a transferable warranty or service, if so it is worth buying. The buyer should not end up overpaying as used computers depreciate at a lightning speed. There are many online auctions, which can give the idea of how much people are ready to pay for a used computer. Unfortunately, there is no reputed or unbiased source for knowing the prices for used computers.

It spending reallocate your clients pc hardware budgets

If your clients’ recent financial results have been so spectacular that they feel now is the time to make significant technology investments in their companies, consider the following alternatives to solely devoting their IT spending to PC hardware purchases. Influencing What Your Clients Do with Budget Surpluses Think about encouraging clients to reallocate the surplus funds for IT spending on something else technology-related that they really need.

Understanding your computer basic terminology

: Have you ever wondered what the names are of the devices connected to, and in, your computer? There are many people out there who have never owned a computer or who have a computer but do not know what the proper terms are for the things that come with it. This article explains what those names are and provides a little bit of information about how they function. Generally, all computers come with a few basic devices. These usually include a Monitor, keyboard, mouse, printer, and the computer (also known as the tower or case). Monitor – The monitor is the device that looks similar to a TV. There are many types of monitors but the most common is a 17 inch CRT (Cathode Ray Tube) monitor. A CRT monitor is very similar to your standard TV. There is a new type of monitor that is becoming very popular, it’s called an LCD monitor. An LCD monitor is quite a bit smaller and the quality is somewhat better. Keyboard – The keyboard is one of the most basic input devices.

This is the device that has all the numbers, letters, and symbols that you use to type words on the computer. Mouse – This is the other most basic input device. It is a small mouse-like device connected to your computer that lets you move the pointer around the screen and click on icons. Computer – This is the device that houses the “Guts” of your computer. Inside is where all of the magic happens. Generally, inside a computer case you will find a hard drive, system board, RAM, network card, and all the other devices that let you do all of the fun things that computers nowadays let you do. Printer – This is the device that lets you turn what you see on your computer, into hard copies on paper. There are many types of printers, such as: ink jet, laser, and dot matrix. Some printers also come with built in scanners (to digitize paper documents), fax machines, and photocopiers. This is just some basic information that has, hopefully, helped you better understand your computer.

You may think that most people should already know this but you might be surprised at how many do not.

Things to know about printer cartridges

When a person first thinks of a printer cartridge, he or she may quickly dismiss it as being just something you buy when your printer has run out of ink. Knowing exactly how a printer cartridge works and the different aspects of buying one, however, can end up saving a person a lot of money in the long run. Investing in printer cartridges is usually not a cheap thing to do, many sell for fifty dollars or more each, and it is a good idea to know all of your alternatives before making any hasty decisions. The printer cartridge works by storing ink inside of it to be used by the printer. When the printer sends a cartridge and appropriate signal, the ink is dropped and shaped into the form of the image or letters needed to be translated onto the sheet of paper. It is important to note, that two separate cartridges are needed for those who need color on their printed pieces. One cartridge will have only black ink and will only function during black and white printings, while the other contains red, yellow, and blue ink and can create different color combinations. The color cartridge is, in general, much more expensive then the simple black cartridge, so it is important not to waste it. It is a good idea, therefore, to not waste color ink unless it is absolutely needed.

For example, printers can sometime be set to print everything, including black and white projects, through the color cartridge. Setting the printer to not do this will save you a lot of money in the future. Another thing that is important to remember about printer cartridges is that many of the big-name companies who also create printers, such as HP, Canon, and Lexmark, will create cartridges that will work only with their printers. These cartridges are often very expensive and overpriced.

This is because the big companies know that most of their consumers have little to no options on alternatives to buy, and that eventually most people will pay the extra money for the printer cartridge they need. It is also due to the fact that many companies like HP will make their printers cheaper to attract more customers and regain the loss through printer cartridge sales. Fortunately for owners of printers, there are other options becoming available. Brands such as Xerox offer cheaper alternatives for printer ink that can work in multiple printers. Because these brands do not create printers themselves, they have no reason to charge more for ink and therefore can offer everyone a better alternative. The best way to find a good option for your printer is to check with a local store to see what different printer cartridges are compatible with your printer. There is no question that a printer cartridge is important to maintaining a good printer and producing quality printed work. Knowing all of the options available to you, however, and practicing good ink maintenance goes a long way in saving money for the future.
