Cache memory is a relatively small amount of high speed memory that resides very close to the CPU. It supplies the CPU with the most frequently requested data and instructions. This is because retrieving information from the cache memory takes a fraction of time lesser when compared to that taken from main memory. Thus it saves a lot of time. Most of the cache memory is incorporated into the processor chip itself. But other means such as on the motherboard or a cache socket near CPU are also possible. Cache components are assigned levels based on how close they work with the processor. For simple example a cache labeled level one is closest to the computer. Level 2 comes next and so on. Computers also have other types of caching other than cache memory. Sometimes main memory is used as cache for hard drive. Thus the term cache refers to all storage technologies used and not specifically just a memory.
