Desktop Computers

Desktop computers in general are designed primarily for use at a desk.  Because they are stationary during their life desktop computers are typically very powerful compared to other types of computers such as a laptop.

The typical desktop computer is loaded with powerful components because size isn't too much of an issue. In contrast a laptop requires components to have been shrunk tremendously for functionality, and in the computer world bigger is often better when it comes to sheer speed.

Desktop computers in the most general terms are made up of separate components including the system unit, monitor, keyboard, mouse, and speakers.  The system unit is the most important piece for it contains the guts and brains of the computer system.  

System units are normally a rectangle box/case that sits on or underneath a desk. Other components, such as the monitor, mouse, and keyboard come in various shapes and sizes but look fairly general across the board.  All connect in some fashion into the system unit completing the desktop computer.
