What is CPU scheduling in an operating system?
a) The process of determining which process will be assigned CPU time next
b) A technique for managing memory allocation
c) A method for handling input/output operations
d) A system for managing file system access
Answer:
a) The process of determining which process will be assigned CPU time next
Explanation:
CPU scheduling is the process by which an operating system determines which process should be assigned CPU time next. It is crucial for multitasking environments, where multiple processes are competing for CPU resources.
The scheduler uses various algorithms, such as First-Come-First-Served (FCFS), Shortest Job First (SJF), and Round-Robin, to decide which process should run. The goal of CPU scheduling is to optimize system performance by maximizing CPU utilization, minimizing waiting time, and ensuring fairness.
Efficient CPU scheduling ensures that all processes get their fair share of CPU time and that high-priority processes are executed promptly, improving overall system responsiveness and performance.
