Multiprogramming vs. Multitasking: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on February 1, 2024
Multiprogramming involves multiple programs running on one CPU, managed by the OS for efficiency. Multitasking involves executing multiple tasks simultaneously by rapidly switching focus.

Key Differences

Multiprogramming is a method where multiple programs are loaded into memory and executed by the CPU, but only one at a time. In contrast, multitasking refers to the ability of an operating system to manage multiple tasks by rapidly switching between them, giving the illusion of parallelism.

In multiprogramming, while one program waits for I/O operations, another program can use the CPU. This maximizes CPU usage. Conversely, multitasking divides CPU time between tasks, ensuring that system resources are efficiently utilized and responsive to user input.
