Reference to context of ch=10 from class 8th

Answer 1

Mutual exclusion is a program which prevents simultaneous access to some shared data. In simpler words, if a process in executing in its critical section, then no other process can be executing in their critical section.

This is used in concurrent programming where multiple threads can access shared resources.

Basically, when CPU is allotted various tasks, it works on a single program and halts the other.

But the time taken is so small that the user fails to notice it.
