ITPEC IP April 2022 — Question 18 of 100
Multitasking is the operating-system function that lets multiple application programs appear to run concurrently. The OS rapidly schedules CPU time among processes or threads and manages their resources. On a multicore processor some tasks may truly execute at the same instant, but the OS scheduling concept is still multitasking.
Answer (d)
Why not others:
- multiuser means supporting sessions for multiple users
- multiprocessing specifically uses two or more processors or processor cores for execution
- multimedia refers to handling combinations of media such as text, audio, images, and video
Key rule: Multitasking concerns concurrent execution of multiple programs; multiprocessing concerns the use of multiple processing units.
