Scheduling and Context Switching

Reading chapters 3,4,5 Comer.

We saw earlier that an operating system gives the illusion of concurrency in a single processor system by switching the CPU among different processes, running one for a period of time before moving to another. We now study two components of this switching:

Context Switching, which consists of stopping one process and starting a new one.

Scheduling, which consists of choosing a new process among the processes that are eligible for execution.
