- In computer memory management, a specialized high-speed storage subsystem. Cache works by storing recently and/or frequently accessed information, where it can be accessed much faster than from where it was obtained. A level 1 cache is built right into the CPU, while a level 2 cache utilizes a memory bank between the CPU and main memory. Level 1 cache is faster, but smaller than level 2 cache, while level 2 cache is still faster than main memory. disk cache uses a section of main memory to store recently accessed data from a disk, and can dramatically speed up applications by avoiding the much slower disk accesses. Also called CPU cache.
- An area of computer storage where the most recently downloaded Web pages may be temporarily placed, so that when one of these pages is returned to, it loads faster. Also called browser cache, Web cache, or Internet cache.
