Can you explain what a task scheduler in an operating system is?

The task scheduler in an operating system is a component that manages the distribution of CPU time among running processes and threads. Its task is to determine which process or thread should be executed at any given moment to ensure efficient resource utilization and system responsiveness.

Main functions of the scheduler:

• Selecting the next process to execute (based on priorities, waiting time, and other criteria).
• Context switching between processes.
• Managing quantum times for processes.

For example, in a multitasking system, the scheduler allows multiple programs to operate 'simultaneously' by quickly switching between them, creating the illusion of parallelism.
