Recovery Glossary > Cache
Cache is the memory area where the recently or frequently used data is
stored for speedy access. It's an area set aside in RAM or a disk to save
frequent and recent used data. Cache is used to optimize data transfer
between system elements with different performance characteristics.
Cache has been classified into disk cache and processor cache. Disk cache
stores information that is recently read from the hard disk in the computer's
RAM and helps in accessing common files and folders faster. Processor
cache is one which stores small amount of information next to the processor
and helps in processing the common instructions efficiently and speeds
up the computation time.
