Explanation

MESI is a cache coherency protocol that supports a shared state. It is a mechanism for maintaining cache consistency between multiple processors in a shared-memory system. The acronym MESI stands for Modified, Exclusive, Shared, and Invalid, which are the possible states that a cached copy of a memory block can be in. The protocol uses bus snooping techniques to detect changes in shared memory, ensuring that the data in the caches of all processors is consistent.
