A critical section is a code segment that can be accessed by only one process at a time. The critical section contains shared variables that need to be synchronised to maintain the consistency of data variables.
Critical Section is the part of a program which tries to access shared resources. That resource may be any resource in a computer like a memory location, Data structure, CPU or any IO device.

The critical section cannot be executed by more than one process at the same time; operating system faces the difficulties in allowing and disallowing the processes from entering the critical section.
The critical section problem is used to design a set of protocols which can ensure that the Race condition among the processes will never arise.

In order to synchronise the cooperative processes, our main task is to solve the critical section problem. We need to provide a solution in such a way that the following conditions can be satisfied. Requirements of Synchronisation mechanisms
