Mutex Semaphore

A mutex semaphore is a specific use case of a
Binary semaphore using Locking algorithm

Stricter and narrower use case (than binary semaphore)

Mutex(mutual exclusion) is object(variable) in process that prevent multi-thread access to data - use locking and unlocking

Mutex - self unlock

mutex is for two process - semaphore is for multi process use critical section

supervise only one resource

All Mutex is Semaphore, Semaphore can be mutex, not all mutexes are Semaphore

mutex is type variable and has function lock and unlock

lock(mutex), unlock(mutex)
