Beginner Topic 10 of 51 Operating Systems
CPU Scheduling
Deciding which ready task runs next.
How it works
The scheduler picks the next ready task according to goals: throughput, turnaround, waiting, response time and fairness. Policies may be preemptive (can interrupt) or non-preemptive.
Where it is used
Linux CFS, Windows priority scheduler.
Common pitfall
No policy optimizes every metric; interactive and batch loads need different tuning.
Where it fits in the course
CPU Scheduling is topic 10 of 51 in Operating Systems, rated Beginner. It follows Context Switching. The next topic is Round Robin Scheduling.
