What Is Scheduling?

The CPU is a scarce resource on modern computers.

When multiple programs (in the form of processes or multiple threads in a process) are run, they must share the processing resources on the CPU. This task of resource allocation is given to a Scheduler.

But, which process/thread gets to be executed first by the CPU, and which one should wait?

To solve this, different scheduling algorithms were developed.

Let’s discuss the 6 important ones in this article.

Note that I am using the term ‘Process’ in this article to refer to a computation task.
