Explore Semaphore in Operating System: Learn its types, operations, advantages and disadvantages, and how it solves classic OS problems.
In theory, a semaphore is a shared counter that can be incremented and decremented atomically. For example, Tasks A, B, and C wish to enter the critical section in the image above. They each call semaphoreTake(), which decrements the counting semaphore. At this point, all 3 tasks are ...
