Question

In a multiprogramming environment __________

(a) the processor executes more than one process at a time

(b) the programs are developed by more than one person

(c) more than one process resides in the memory

(d) a single user can execute many programs at the same time

This question was addressed to me in unit test.

This is a very interesting question from Process Scheduling Queues in section Processes of Operating System

Answer 1

Right choice is (c) more than one process resides in the memory

The best I can explain: In a multiprogramming environment more than one process resides in the memory. Whenever a CPU is available, one process amongst all present in memory gets the CPU for execution. Multiprogramming increases CPU utilization.
