WebThe operations must be accomplished in proper order or sequentially. This unwanted situation is termed as a race condition. Mutual exclusion can be used to resolve issues related to race conditions. That means it will ensure that only a single process is allowed to enter into the critical section at the same time. WebThe mutual exclusion requirement is assured. Suppose instead that both processes are in their critical section. Since only one can have the turn, the other must have reached the while test before the process with the turn set its flag. But after setting its flag, the other process had to give away the turn.
