Scheduling

Question

Which of the following event doesn't effect a process in the running time ?

a) Interupt b) exit c) I/O event d)schedular dispatch

Comments

here the answser is schedular dispatch.

I think none of them is the answer because when a process is dispatched for cpu cycle then the dispatcher will change the state of currently running process to ready state.

Believe in the state diagram. :P :P

Answer 1

Correct Answer is D) Schedular Dispatch

Because Interrupt causes immediate attention of processor. Exit will terminate the program and I/O event shift the process from processor to Blocked Queues.

Why schedular dispatch? It will also effect the state of a running process.As it is return in Galvin that when a dispatcher gives the cpu cycle to a ready process it will save the state of the current running process and load the new process

Here effect means state change, nothing else. Thats it.
