what is cache memory?

Answer 1

Look it up on Wikipedia.org

In general if you're talking about the cache on a CPU, it is memory that is located directly on the processor die which gives it access to run at faster speeds. L1 and L2 cache, for example, typically run at the same speed as the CPU (this was not always the case in older processors).

It is a buffer that stores data that is currently being used or about to be used by the processor. It's there because access is much, much faster than getting it from RAM.

Answer 2

More generally, it is memory closely associated with a processor or storage device, designed to speed up operation. Disk drives have cache memory, for instance, because it is useful to store pointers to indices and blocks of data likely to be read next.

Answer 3

hey cache memory is an memory block which is present between cpu n ram most frequently used instructions r stored in it so that cpu need not refer the main memory frequently by accessing the ram again it is of two types level 1 n level2 cache memories

Answer 4

Cache memory is the intermediate buffer between processor and main memory.It is used inorder to reduce the speed mismatches between processor and main memory.
Processer executes the frequently used instructions from cache without going to main memory.

Answer 5

the memory that has been stored in buffer this is done as if we start writing small small bits of data on a magnetic disk or anythin the total rate will be affected so they store it in buffer first that memory is called cache memory

Answer 6

cache memory is the fastest and small amount of memory for temporary storage of datas.it is placed in a processor.
generally used for speedy access and temporary storage.

Answer 7

cache memory is very memory it has both advatages and disadvantages they are
*they are faster
*they are costly
*they generate huge heat

Answer 8

it is ussed to measture computer speed, it includes in processor, much cash means much speed u have
