What are the 4 actions performed by a dispatcher when a program's time slice expires?

When a program's time slice expires, a dispatcher typically performs the following four actions: first, it saves the current state of the running process, including its CPU registers and program counter. Next, it updates the process control block (PCB) to reflect that the process is no longer in the running state. Third, it selects another process from the ready queue to run next, based on the scheduling algorithm in use. Finally, the dispatcher loads the saved state of the selected process into the CPU, enabling it to resume execution.
