Answer 2

CACHE is a reserved access area of the main memory or of a storage device.

• As mentioned, cache is a high-speed reserved area of the main memory that can be used to access information.

• There are basically two types of cache: memory cache and disk cache.

• Memory cache is a part of the high speed SRAM(Static Random Access Memory). In the memory cache, the computer keeps the frequently accessed information so that information retrieval may be faster and more efficient.

• Disc cache memory also relates to frequently accessed information but instead of the SRAM, this cache reserves a part of the conventional main memory. So, more frequently used data from the disc is stored in a memory buffer. Any information retrieved from the disc is first checked in the memory buffer and if found there, the retrieval is considerably faster.
