ITPEC IP October 2024 Question 22
ITPEC IP October 2024 — Question 22 of 100
Multitasking is the OS function that allows multiple application programs to make progress concurrently on one PC. The operating system schedules CPU time among processes and manages memory, devices, and I/O. While one task waits for a network download, another can use the processor for spreadsheet calculations, making both activities appear to run at the same time.
Answer (d)
Why not others:
- (a) Virtual reality creates an immersive simulated environment
- (b) Dual core is a hardware architecture with two processor cores, not the OS scheduling function itself
- (c) Dual system is not the standard term for concurrent execution of applications
Key rule: Multitasking is software scheduling of multiple tasks; multiple CPU cores can improve its true parallel execution but are not required for time-sliced concurrency.
