Using TWO practical life experiences, discuss the critical section problem in
the context of an operating system

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

  1. The critical section problem would cause the processes to change shared resources, writing file, updating table, etc.
  2. When one process enters the critical section, no other process would be in its critical section.

What is an operating system?

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.

What is the critical section problem?

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.

Example of critical section problem in the context of an operating system is when process A change the data in a memory location  and process C want to read the data from the same memory.

What is  critical section problem in OS?

The critical section problem can be regarded as the problem  that involves the notification that one process is executing its critical section at a given time.

It should be noted that ,The critical section  can be seen in code segment  when there is access to shared variables .
