Difference between multitasking and multiprogramming operating systems?

Multitasking refers to the ability of an operating system to execute multiple processes simultaneously by rapidly switching between them, giving the illusion that they are running at the same time. In contrast, multiprogramming is a method where multiple programs are loaded into memory and the CPU switches between them, but it may not use time-sharing techniques, leading to less interactive performance. While multitasking is often user-focused, enhancing responsiveness, multiprogramming is more about maximizing CPU utilization. Both approaches aim to improve efficiency, but they operate at different levels of process management.
