Hi All, Can some one tell me the differences between semaphores,critical section and mutexes.When should they be used(i know these are used for synchronization between threads) and the advantages/disadvantages of them over the other. Thanks in advance Regards Raghu

in one sentence. Semaphore can be used to manage resources, criticalsection to synchronize access to shared data within same(single) process and mutex to synchronize access to shared data among different process also.
