That resource may be any resource in a computer like a memory location, Data structure, CPU or any IO device.
A mutex is a locking mechanism that sometimes uses the same basic implementation as the binary semaphore. The differences between them are in how they are used. While a binary semaphore may be colloquially referred to as a mutex, a true mutex has a more specific use-case and definition, in that only the task that locked the mutex is supposed to unlock it. This constraint aims to handle some potential problems of using semaphores: WebSemaphores in OS (Operating System) To get rid of the problem of wasting the wake-up signals, Dijkstra proposed an approach which involves storing all the wake-up calls. …
