time slice

operating system (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 external

events quickly enough.
