What is L2 Cache

Cache Memory acts as a high speed buffer between the RAM and CPU. Cache RAM operates at higher clock frequencies than normal RAM. This allows the data to be read more quickly from the cache than the main memory.Cache memory functions as a “near store” of RAM i.e. these are the stores which the CPU can always be supplied from. There are at least two close stores which are called Level 1, Level 2 cache (Level 3 cache is also sometimes there e.g. in Intel Itanium processors, Level 3 cache is there). The cache memory ensures that data is constantly fetched from the RAM so that CPU does not sit idle. » What is L2 Cache
