A portion of main memory used as a buffer to hold data temporarily that is to be read out to disk is called a disk cache. A disk cache is used to improve the performance of a computer system by reducing the number of disk reads required, thereby reducing the latency of the system. A disk cache can also be used to temporarily store data that is frequently accessed or used, in order to speed up the response time of the system.
