Cache consistency is important because without it, different processors may have different versions of the same data, which can lead to data inconsistencies and errors in the system. Different cache consistency protocols, such as MESI and MOESI, are used to maintain cache consistency in modern computer systems. These protocols define a set of rules and states for cache coherence and ensure that all caches in the system have the same view of the shared memory.
