Disk cache definition

Disk cache is a temporary computer memory that stores frequently used data. It essentially acts as a bridge between the slower, non-volatile storage (like hard drive) and the computer’s main memory (RAM). Such cache ensures that commonly accessed information is readily available. The computer’s operating system handles the management of disk cache.
