Explain the difference between multitasking and multiprogramming.

• Multitasking and multiprogramming are essentially the same concept with different names.

• Multitasking involves running multiple programs simultaneously on a single processor, while multiprogramming involves running a single program on multiple processors.

• In multitasking, tasks are executed sequentially one after the other, while in multiprogramming, tasks are executed concurrently.

• In multitasking, tasks are executed concurrently by rapidly switching between them, while in multiprogramming, multiple programs are loaded in memory simultaneously and CPU scheduling is used to switch between them.
