An operating system (OS) can be defined as a system software that's usually pre-installed on a computing device by the manufacturers, so as to manage random access memory (RAM), software programs, computer hardware and all user processes.

A critical section problem can be defined as a code segment in which all of computer processes access and make use of shared resources such as digital files and common variables, as well as performing write operations on these shared resources.

This ultimately implies that, a critical section problem can be used to design and develop a secured protocol followed by a group of computer processes, so that no other process executes in its critical section when another process has entered its critical section.

For instance, given a system of n processes (P₀, P₁, ....… Pₙ₋₁} with each process having critical section segment of code.
