The main function of a dispatcher in a computer system is to handle the process scheduling. Here are the steps to explain its function:

1. Process Selection: The dispatcher is responsible for selecting processes from the queue. These processes are usually in a ready state, waiting to be executed.

2. Context Switching: The dispatcher performs context switching, which is the process of storing and restoring the state of a process so that execution can be resumed from the same point at a later time. This allows multiple processes to share a single CPU.

3. Switching to User Mode: After selecting a process and loading its context, the dispatcher switches the CPU to user mode, where the process can be executed.

4. Jumping to the Proper Location: The dispatcher jumps to the proper location in the user program to restart the program for the selected process.

In summary, the dispatcher is a crucial component of the operating system that manages the execution of processes by the CPU.
