What is time-slice? how is the end of the time slice indicated?

Time-slice is a part of the preemptive process - a scheduling algorithm that will return from the running state to the ready state in a system that can favor another process in the meantime (in order to satisfy the scheduling policy's priority constraint).

Time- slice is that period of time in which a process is allowed to run in a preemptive multitasking system. The end of one is indicted by the occurrence of a signal called.
