Hardware

A desktop computer is a personal computer in a form intended for regular use at a single location desk/table due to its size and power requirements, as opposed to a laptop whose rechargeable battery and compact dimensions allow it to be regularly carried and used in different locations. The most common configuration is a computer monitor, keyboard and mouse, and a case that houses the main components of the PC, namely the power supply, motherboard, hard drive, optical drive, and previously the floppy drive. The form factor of the case is typically an upright tower or (horizontal) desktop. All-in-one computers, that integrate the monitor and main PC components in one unit, are often categorized under the desktop computer umbrella, particularly if they require an external power source and separate keyboard/mouse. The desktop category has also encompassed home computers and workstations
