Preliminary Analysis of Synchronization and Mutual Exclusion of Process in Operating System

The synchronization and mutual exclusion between operating system processes is the key point and difficulty of this course. Synchronization is the process of sending messages with each other between groups of concurrent processes in an asynchronous environment due to direct constraints, making all processes carried out at a certain speed. Mutual exclusion means that two or over two concurrent processes that share this resource cannot go into the critical zone simultaneously. There are four types on the realization mechanisms of process synchronization and mutual exclusion: Semaphore, monitor, rendezvous and distribution system.
