Cache Memory

Caching is a technology based on the memory subsystem of any computer. The majoraim of a cache is to accelerate the computer while keeping the cost of the computer low. Caching let to do computer tasks more quickly.

Cache technology is the utilities of a faster but smaller memory type to accelerate a slower but larger memory type.

Cache is small high speed memory generally Static RAM that have the most recently accessed pieces of the time it takes to  an instruction (or piece of data) into the processor is very long when compared to thetime to execute the instruction.

When by using a cache, we might check the cache to see if the item is in the cache. If it is, that is known a cache hit. If not, it is known a cache miss and the computer might wait for a round trip from the larger and slower memory area.

A cache has some maximum size that is very small then larger storage area.

Cache memory helps by decreasing the time it takes to move information to processor  & from the processor. Cache memory permits small portions of major memory to be accessed 3 to 4 times faster than DRAM It applies "Locality of Reference." At any time the processor will be accessing the memory in localized or small region of memory.  The cache loads this region  byallowing the processor to access the memory region faster.
