Describe the actions taken by a kernel to context-switch between processes.

Expert Solution

The action taken by a kernel to context switch between processes are --

To switch CPU to other process, it has requirement of performing a state save of the current process and state restore of different process. this task is called as context switching.
When the context switching ocuur the kernel switching context of old process in PCB and loads saved context of new process scheduled to run.
context switch time is pare overhead because system do not have any useful work during that time.
It depend on the processor which have large number of register so it do not need to unload old PCB because it has enough space to store frequently used processes PCB.
The Operating system need to save the PC and user stack pointer for the process which is currently executing process, in response to clock interrupt and transfer control to kernel clock interrupt handler.
The clock interrupt handler which save rest of register and other machines state of floating pointer register in process PCB.
then the operating system identify schedule and determine next process to be execute.
Then the operating system retrives the state of next process from PCB and and restore the register.
