Critical section

In concurrent programming, a critical section is a piece of code that accesses a shared resource (data structure or device) that must not be concurrently accessed by more than one thread of execution

That part of the program where the shared memory is accessed is called the Critical Section.

A section of code or collection of operations in which only one process may be executing at a given time, is called critical section.
