What do you understand by multitasking?Explain cooperativemultitasking ?
Nadusha1986 [10]

Answer: Multitasking is the ability of the operating system by which a processor is able to process multiple task at the same time.

Cooperative multitasking is non preemptive multitasking where the processor is assigned to a single process and does not preempt  until it completes its jobs or moves to a waiting state.

Explanation:

In Multitasking jobs are executed at a faster rate than as many jobs or tasks can be assigned to the processor at the same time.

In cooperative multitasking due to the non preemptive nature a single job could be assigned to the cpu at a time.
