The PC computer is valued for its versatility and affordability. By definition, a personal computer is any machine designed for a single end user, as opposed to mainframe systems that support multiple users or large data-processing units which demand the effort of many people to operate properly.
A PC computer can be either a desktop or a laptop, and even more variations have been introduced in recent years. The pocket PC, home theater PC, nettop, netbook, tablet PC and ultra-mobile PC are all examples of new variations on the traditional computer made possible through improvements and innovations in core technologies.
Key Features of a PC Computer
The computer hardware components that are typically part of a standard PC setup are usually housed in a computer tower and include the central processing unit (CPU), motherboard, sound and video cards, optical disc reader/burner, memory card and hard drive.
A keyboard and mouse are must-have peripherals, but you can also add additional components depending on your needs and budget. Popular add-ons include webcams, printers and scanners. You'll also need to have a modem of some sort if you plan to use your PC computer to connect to the Internet.
