WebThere are the following two solutions to avoid race conditions. Mutual exclusion Synchronize the process In order to prevent the race conditions, one should ensure that only one process can access the shared data at a time. It is the main reason why we need to synchronize the processes. Another solution to avoid race condition is mutual exclusion.
