How do I fix CPU scheduling problems?
Think of CPU scheduling algorithms in OS as the maestros of this operation, deciding who gets attention and when.
Various strategies include First-Come-First-Serve (FCFS), Round Robin, and Priority Scheduling.
Each brings a unique flavor, ensuring no task goes unserved.
However, not all tasks are created equal.What is the major problem with priority scheduling algorithms and give the solution to the problem?
FIFO, priority scheduling, and shortest-job-first are susceptible to starvation.
What is CPU scheduling algorithms with example?
A major problem with the priority scheduling algorithm is indefinite blocking or starvation.
This algorithm can leave some low priority processes waiting indefinitely.
The solution to the problem of starvation is aging.
