CPU Scheduling (Round Robin)

Operating systems utilize Queues to manage processes competing for CPU time. Round Robin assigns a fixed time quantum to each process in FIFO order.

The Ready Queue

When you open an app, its process goes into a "Ready Queue". The OS pulls from the front of this queue to assign it to a CPU core.

Time Slice (Quantum)

In Round Robin, the CPU only runs a process for a few milliseconds. If it doesn't finish, it gets paused (preempted) and pushed to the back of the queue.

Fairness

This strict FIFO rotation ensures that no single heavy process can freeze the entire computer, giving the illusion of multitasking.
