cachememory is a collection of data duplicating original values stored elsewhere or computed earlier, where the original data is expensive (usually in terms of access time) to fetch or compute relative to reading the cache. Once the data is stored in the cache, future use can be made by accessing the cached copy rather than refetching or recomputing the original data, so that the average access time is lower.using cache as big as as hard disk wld deploy its use ;it is used to increase the thruput by giving it a quick access this is done wen it is very small n scanning the whole memory takes very less time...but having cache large ill creat a problem where it will b as useless in frequent memory acces as hard disk is....

cache memory is also a  mamory which can directly communicate with the processor.
it is used for there is no mismatch between processor and memory so we use cache memory.but metter is that it size is very short because of it cost
it is consist of SRAM which consist of there are many number of transistor so its cost is high.

Cache memory is the fastest memory (after registers),which is situated between RAM and CPU. Data required by the user will stored in cache so whenever data is required CPU first check this memory and if it is not available then it will search in RAM & after that in secondary storage devices. so basically cache is directly accessible memory this is reason it is fast & costly.

it is small because if we have data(s) in TB then it will take more time (computations) to locate that particular data. then the reason behind the cache memory will finished. eg if we have cache of 2GB then CPU has to scan at max 2GB only rather then 4GB RAM or 2TB secondary memory.

Cache Memory Placed B/w RAM and CPU. It Is Much More Faster Than RAM ,and Store Frequently Used Data so We Access them More Quickly .increasing the size may lead to latency and fail attempt to read / write problems. Cache Memory prices is Very High .
