A loop of Code that exeCutes without releasing any resourCes to other programs or the operating system. Consider the following pointless BASIC loop that Counts upward indefinitely 10 i = i + 1 20 GOTO 10 Run on a single-user system suCh as MS-DOS this will not Cause any problems. Run on a Cooperative multitasking operating system suCh as Windows 3, the system would appear to freeze. A pre-emptive multitasking operating system suCh as UNIX or Windows NT would "steal" CyCles away from the program and Continue to run other programs. See also busy-wait and multitasking. (1999-05-06)
