(1) Synonymous with desktop computer. For example, the phrase "the IT department supports 150 desktops" means it is responsible for maintaining 150 user computers. In such cases, laptop computers may be counted as desktop computers.

(2) A prefix attached to the name of personal computer applications that perform functions previously available only on large workstations and mainframes; for example, "desktop publishing" and "desktop mapping." With the advent of smartphones and tablets, "mobile" replaced desktop as the prefix in vogue.

(3) The screen appearance after logging onto a desktop computer. The desktop is actually a folder that holds files and folders like any other folder; however, it remains on screen in the background at all times, ostensibly simulating a physical desktop. The desktop also includes menus and icons for launching applications and managing the computer. See wallpaper.
