Memory caching (often simply referred to as caching) is a technique in which computer applications temporarily store data in a computer's main memory (i.e., random access memory, or RAM) to enable fast retrievals of that data. The RAM that is used for the temporary storage is known as the cache.

Types of cache memory
- L1 cache, or primary cache, is extremely fast but relatively small, and is usually embedded in the processor chip as CPU cache.
- L2 cache, or secondary cache, is often more capacious than L1. ...
- Level 3 (L3) cache is specialized memory developed to improve the performance of L1 and L2.
L2 and L3 caches are bigger than L1. They are extra caches built between the CPU and the RAM. Sometimes L2 is built into the CPU with L1. L2 and L3 caches take slightly longer to access than L1. The more L2 and L3 memory available, the faster a computer can run.
The "size" of the cache is the amount of main memory data it can hold. This size can be calculated as the number of bytes stored in each data block times the number of blocks stored in the cache.
