What is the initial value of the semaphore to allow only one of the many processes to enter their critical section.
The initial value of the semaphore to allow only one of the many processes to enter their critical section is 1.
A semaphore is as an object with an integer value that we can manipulate with two routines. Because the initial value of the semaphore determines its behavior, before calling any other routine to interact with the semaphore.
we declare a semaphore s and initialize it to the value of 1.
A semaphore is a variable or abstract data type used to control access to a common resource by multiple processes in a concurrent system such as a multitasking operating system. A semaphore is simply a variable. This variable is used to solve critical section problems and to achieve process synchronization in the multiprocessing environment.
