Question

Which one or more of the following CPU scheduling algorithms can potentially cause starvation?

Answer checking is unavailable for this question. You can review the published solution without a score.

Correct answer (A) First-in First-Out; (C) Priority Scheduling; (D OR C); (D) Shortest Job First Solution Starvation occurs when a process is perpetually denied necessary resources (like CPU time). (A) First-in First-Out: Every process that enters the queue will eventually reach the front and be executed. No starvation. (B) Round Robin: Every process gets a fixed time quantum in a cyclic manner. No starvation. (C) Priority Scheduling: A low-priority process may never execute if higher-priority processes keep arriving. This causes starvation. (D) Shortest Job First: A long process may never execute if shorter jobs keep arriving. This causes starvation. Turn this into a strength.
