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);
Maximum channel utilization in a LAN is defined by frame time (t f ) and propagation time (t p ). It is defined by (A) t p /t f (B) t f /t p (C) 1 + (t f /t p )
