◊ TIME SLICE
time slice
(Or "time quantum", "quantum") The period
of time for which a process is allowed to run uninterrupted in
a {pre-emptive multitasking} {operating system}.
The {scheduler} is run once every time slice to choose the
next process to run. If the time slice is too short then the
scheduler will consume too much processing time but if it is
too long then processes may not be able to respond to extenal
events quickly enough.
