We all know it is an IPC and it is mainly required to have Synchronization of shared memory access among different threads or process.
hmmm .... even mutex does the same thing... They too synchronize the access of the shared memory... then what is the difference..??
semaphore allows n number of users to access the same resources. we go for semaphore only when the resource that can handle some n process/threads at the same time.
Mutex is a semphore with a value 1.
Only one user can access the shared resources at a given time for mutex.
