WebDec 13, 2024 · Mutual exclusion is a property of process synchronization which states that “no two processes can exist in the critical section at any given point of time”. The term was first coined by Dijkstra. Any process synchronization technique being used must satisfy the property of mutual exclusion, without which it would not be possible to get rid ... WebMar 24, 2024 · The critical section is a part of the program code, where we want to avoid concurrent access. We can use a binary semaphore to solve the critical section problem.
