What is the use of an interrupt in a computer system?

Correct option is C

An interrupt allows the CPU to temporarily halt its current task to manage urgent tasks, such as handling input/output operations or responding to critical events. This enables the system to quickly address time-sensitive operations. Once the interrupt is managed, the CPU resumes its previous task.
Important Key Points:
1. Interrupts ensure that high-priority tasks, like input/output requests, are addressed immediately.
2. They allow the CPU to efficiently multitask, switching between processes as needed.
Knowledge Booster:
· Stop CPU tasks: This does not describe an interrupt; the CPU pauses tasks temporarily but resumes them after handling the interrupt.
· Allocate memory: Memory management is handled by the operating system, not interrupts.
· Save data: Data storage operations are unrelated to interrupts, which manage real-time tasks.
· Protect against malware: Interrupts do not provide security; antivirus programs are responsible for malware protection.
