Question

Which module gives control of the CPU to the process selected by the short-term schedular?
1. Dispatcher
2. Interrupt
3. Schedular
4. Threading

Answer 1

Correct Answer - Option 1 : Dispatcher

Dispatcher module gives control of the CPU to the process selected by the short-term schedular?

• Short-term schedular: selects the processes that are ready to execute and allocates the CPU to one of them
• Dispatcher: Context switches, in which the dispatcher saves the state of the previous process then the dispatcher loads the saved state of the new process selected by the short-term scheduler

• Mid-term scheduler: swap the processes from the wait state to hard disk
• Long-term scheduler: bring the processes to main memory from the hard disk
