This is also known as “mutex” which stands for mutual exclusion. takes only the values 0 and 1 is called a binary semaphore. They are kind of weak semaphore.Ī semaphore whose integer component S.L. Here we will discuss the types of Semaphores as follows.Ī semaphore whose integer component can take arbitrary non-negative values of S.L. Semaphore S 0)Īccording to the value of S.L., if it is empty increment the value of the integer and if it is non-empty unblock q an arbitrary of the set of processes blocked o S.L. Semaphore S must be initialized with a value of S.V. When a process executes its final statement. The process is activated at some point and becomes ready. It can be awakened by some external actions.

The processes not ready not a candidate for a running process. The process runs when no processes are running

This will help in understanding semaphore. Let’s go through the stages of the process that comes in its lifecycle.
