On Linux, A semaphore is a System V IPC object that is used to control utilization of a particular process.. Semaphores are a shareable resource that take on a non-negative integer value. They are manipulated by the P (wait) and V (signal) functions, which decrement and increment the semaphore…

Semaphore in Linux plays an important role in a multiprocessing system. We need to review the semaphore status if we need to kill unwanted entries to free up the memory allocated to the server. Semaphores are IPCs, which means Inter-Process Communication Systems used to allow different processes to communicate with eac

Semaphores can best be described as counters which are used to provide synchronization between processes or between threads within a process for shared resources like shared memories. System V semaphores support semaphore sets where each one is a counting semaphore. So when an application requests semaphores, the kernel releases them in sets.

Using Semaphores in Linux Semaphore as used in an operating system to restrict the access to resources by multiple processes at the same time. When a semaphore is used to restrict the access to only one process at a time, it is termed as mutex, as it serves the purpose of mutual exclusion.

Semaphores is just a counter mechanism - only problem is that this counter is also globally accessible by all the CPU concurrently so how are you going to synchronize them so that only one CPU can increment or decrement the counter at any one time...
