Computer Accessories

Many additional accessories are available for computers and although these are not required, they can come in handy depending on what you're going to use your computer for. For example, if you plan on printing, you will need a printer--but it is not required to make the computer run.

Network Card – If you want to connect to a Local Area Network (LAN) or the Internet, you'll need this card (or a modem). This works by receiving and sending information (data packets) over a local network or from/to the internet using a high speed cable line.
Modem –This works like a network card, only it's much slower and uses a standard phone line to communicate to the outside world.

Printer – This is used for transferring data from the PC and printing it on a piece of paper. Printers can print in either black and white or color.

Scanners – These are similar to printers however, they can scan images that can either be viewed on the monitor screen or printed out. There are also scanners/printer combinations that print and scan using one machine.

Speakers – These are used to play sound. They can either be built-in or connected by using cables.

Webcam – This is a camera that can be used with your computer that will allow you to communicate with others who have webcams. You can also take photos and record videos with a webcam.
