Discover Ways To Extend Your Computer's Capabilities

By: Colon Bolden


Once your computer knowledge and confidence grows, you will be eager to expand your personal computer's capabilities. A wide range of devices is available that will make working with your computer even more interesting and enjoyable. Here are some extras that can be collected over time:

- Modems. One very important aspect of modems is never try to buy a used one. Because, how are you going to know if its actually going to work, and it could be also missing alot of instructions for installation and might not have the driver software CD that comes with it. A new modem will be more money, but the money you save getting a used modem is not worth the trouble when trying to install right or may wear out much sooner than a new one. Basically, there are two main types of modems. Internal modems are installed inside the system unit in one of the spare slots at the back. External modems sit outside your computer, on your desk, and plug into one of the serial ports at the back of the system unit. Once you have a model, you can connect to the internet, send emails, and send and receive faxes, using your computer as a fax machine.

- Scanners. The basic operation of the scanner is to read the image of the object placed on the scanner pane of optical reading feature which converts the analog code into digitized code. A scanner will transform your paper images and photo prints into graphic files that you can then edit and use on your PC. Flatbed scanners, in which you lay your images face down and a light-sensitive device passes undernealth, are the most versatile and affordable type of scanner. Buy a scanner with a resolution capability of atleast 300dpi.

- Digital Cameras. Digital cameras look similar to ordinary cameras, but take photographs without using any film. The picture is stored as a graphic file that you can transfer directly to your computer through a connection cord. Good quality cameras are quite expensive, but it's worth remembering that you won't need to buy film and get it developed, and you don't need a scanner. Care should be taken while transferring the files from your camera to your computers. Improper transferring may lead to short circuiting of your digital camera. Never try to disconnect your device while transferring files from your digital cameras to the computers.

- Joysticks. If you're a fan of computer games, a joystick is essential. Many home PCs come with their own joystick, but you can also buy joystick with extra feature buttons and better grips. They plug into a port in your system unit. The best joysticks are those that also provide feedback. It's also possible to buy steering wheels and pedals for driving games. If you have the opportunity, you should try to use the joystick in-store before purchasing it. If the joystick is uncomfortable or you are having to use too much force when maneuvering it in different directions, you should probably pass on that model of joystick because it may cause unnecessary wrist strain and leave you unable to have the fast reaction time that new computer age games require.

- Video Cameras. If you mount a small video camera on the top of your computer, you can conduct video conferences. These small cameras are also used for the WebCam sites on the internet. Bear in mind that video conferencing require a powerful PC, and without special high-speed phone lines, the picture can be jerky and the sound can stutter. Looking for the best video cameras often is successfully done with a few simple steps. Know your options in the marketplace and know what features will be important to you. Make sure you have a set price range. Take a look at the reviews as well as talking to people who have purchased and understand how to use a video camera.

- Microphones. They are available for common computer usage like recording a narration. Many computers come with a microphone in the accessories that come with it. Your accessory microphone may be alright to begin with but it probably will not be professional quality but should be ok because it all depends on what your needs are. But it is now possible to use a microphone in conjunction with speech-recognition software. This means that you don't have to type in anything you just have to say it. Unless you spend a long time teaching it to recognize your voice, it may give poor results.
Your added devices can also be bought to make the most of existing on-screen entertainments. The new generation of joysticks for instance, really take game playing to a new dimension. Like I mentioned earlier, you can have all these over time but you don't need to buy everything on the same shopping trip.
