WebInformally, a critical section is a code segment that accesses shared variables and has to be executed as an atomic action. The critical section problem refers to the problem of … WebExit Condition: Every critical section must end with an exit condition which alerts the system regarding the exit. A solution to a critical section problem must satisfy three conditions; a) Mutual Exclusion: If a process A is executing in its critical section, then no other processes must execute in its critical section.
