Question

What is convoy effect ?
All process waiting for the long process to complete
All process waiting for the small process to complete
Process in not present in main memory
None of above

Answer 1

Answer:

The term Convoy Effect is a phenomenon related to the algorithm with the First Come First Serve, FCFS features, in which the whole Operating System becomes slower on account of few slow processes.

FCFS algorithm is non-pre-emptive type in nature, which means, once CPU time has been assigned to a process, other processes can receive  CPU time only after the current process has been finished.

This property of FCFS scheduling transforms into the situation called Convoy Effect.
