Which of the following application makes use of a circular linked list?

  • A. a) Recursive function calls
  • B. b) Undo operation in a text editor
  • C. c) Implement Hash Tables
  • D. d) Allocating CPU to resources
Correct Answer: D. d) Allocating CPU to resources
ircular linked lists are particularly well-suited for scenarios where a cyclical or repetitive pattern is involved. In the context of CPU allocation, this is precisely the case.

Round-robin scheduling: This is a common algorithm used to allocate CPU time to multiple processes.

Circular nature: A circular linked list forms a loop, perfectly representing the cyclic nature of round-robin scheduling.

Efficient iteration: The circular structure allows for easy traversal from one process to the next without the need for special end-of-list checks.

By maintaining a circular linked list of processes, the operating system can efficiently cycle through them, granting each process a time slice of CPU time in turn. Once the last process is served, the list wraps back to the beginning, ensuring fairness and equal opportunity for all processes.
