Difference among pre-emptive and non pre-emptive scheduling, Operating System

Q. Define the difference among pre-emptive and non pre-emptive scheduling.

Answer: Pre-emptive scheduling permits a process to be interrupted in the midst of its execution taking the CPU away and allocating it to another process. Non pre-emptive scheduling makes sure that a process relinquishes control of the CPU only when it finishes with its current CPU burst.
