The MESI protocol is a cache coherency protocol used in multi-processor systems to ensure all processors have a consistent view of data in their caches. It uses four states for each cache line: Modified, Exclusive, Shared, and Invalid, which are determined by a set of bus and local events, such as read/write operations or snooping on the bus.
