How semaphores implement mutual exclusion?

Mutual-exclusion implementation along with semaphores:

Assume that there are n-processes and they share a semaphore, mutex (standing for mutual exclusion), initialized to 1. All processes Pi is organized as illustrated below:

do{

wait(mutex);

critical section

signal(mutex);

remainder section }while(1);
