Critical Section

A critical section refers to a part of a program where shared resources, such as data or variables, are accessed. If multiple parts of a program try to use these resources at the same time, it can lead to errors or inconsistent results. To prevent this, only one part can access the resource in the critical section at a time. Proper management of critical sections is essential in programming and computer systems to ensure that data remains correct and reliable, especially in multitasking or multi-threaded environments where many processes run simultaneously.
