Desktop computers tend to come in three main parts: the case that contains the actual computer (motherboard, disk drives and power supply), the screen, and the keyboard and mouse.
Not usually portable, the computer will sit on or under the desk with the keyboard and monitor on top.
Desktop computers are usually more powerful than a similarly priced laptop.
"Desktop" in computer terminology may also refer to the computer's background over which all program windows are placed. A desktop, when used in this context, may contain icons, a background image, widgets or file folders.
