A lock and a mutex are two names for the same thing. A semaphore is not a mutual exclusion mechanism (should not be used for it). What is a critical section? How do we safely implement it? A critical section is the restricted area of a program where only one process can have access to those shared resources at a time. To safely implement it, we can use syncronization techniques like locks, mutexes, and semaphores to control the access to the critical section ensuring only. one process at a time has access to it.
