This protection mechanism is called mutual exclusion.
What is mutual exclusion. It is a basic requirement in concurrency control to prevent race conditions. By seeing this lecture you. Mutual exclusion is a concurrency control property which is introduced to prevent race conditions.
In computer science mutual exclusion refers to the requirement of ensuring that no two concurrent processes are in their critical section at the same time. Message passing is the sole means for implementing distributed mutual exclusion. It is the requirement that a process can not enter its critical section while another concurrent process is currently present or executing in its critical section ie only one process is allowed to execute the critical section at any given instance of time.
Mutual exclusion ensures that concurrent access of processes to a shared resource or data is serialized that is executed in a mutually exclusive manner. This concept is used in concurrent programming with a critical section a piece of code in which processes or threads access a shared resource. Prevents race around condition.
Mutual exclusion is a property of process synchronization which states that no two processes can exist in the critical section at any given point of time. A mutual exclusion mutex is a program object that prevents simultaneous access to a shared resource. What are the limitations of the interrupt disabling for mutual exclusion.
It must be holding true for non-shareable resourcesNon-sharable resources include printer memory space etc. In a distributed system shared variables semaphores or a local kernel cannot be used to implement mutual exclusion. Here a critical section refers to a period when the process accesses a shared resource such as shared memory.
A mutual exclusion mutex is a program object that prevents simultaneous access to a shared resource. Mutual exclusion is a basic synchronization primitive used to ensure thread safety when accessing shared variables. Mutual exclusion is one of the conditions for a deadlock to occur.
