Mutual exclusion is a property of concurrency control that prevents race conditions by ensuring one thread of execution never enters a critical section while another concurrent thread is already accessing it. It requires that shared resources are accessed by only one thread at a time, preventing data inconsistency. Mutual exclusion was first identified and solved by Edsger W. Dijkstra in 1965 and is used to avoid race conditions when multiple threads access the same memory address.
