CPUs are extremely fast, so if a program is processed for even a short time it can do quite a lot. The OS decides the best way to swap between running, runnable and waiting processes. It controls which process is being executed by the CPU at any point in time, and shares access to the CPU between processes.
What happens when a program is suspended?
Ans: Suspended Process are those process which has been turned off temporarily. When a process is temporarily suspended then later on it will restart from exactly the same state where it was stopped. So, the state of those processes must be stored somewhere else on your PC.
When CPU stops executing instructions and saves the current program state and execute ISR is called?
When an interrupt occurs, it causes the CPU to stop executing the current program. The control then passes to a special piece of code called an Interrupt Handler or Interrupt Service Routine.
