what is synchronization. What is mutual exclusion. Mutex: Refers to a resource that allows only one visitor to access it, with uniqueness and exclusion. However, mutual exclusion cannot limit the order in which visitors access resources, that is, access is unordered.Synchronization: Refers to the mutual exclusion of the basis (in most cases), through other mechanisms to achieve the visitor's orderly access to resources. In most cases,
