Locality of refere

In computer science, locality of reference, also known as the principle of locality, is a phenomenon describing the same value, or related storage locations, being frequently accessed. There are two basic types of reference locality. Temporal locality, refers to the reuse of specific data, and/or resources, within a relatively small time duration. Spatial locality, refers to the use of data elements within relatively close storage locations. Sequential locality, a special case of spatial locality, occurs when data elements are arranged and accessed linearly, such as, traversing the elements in a one-dimensional array.

Locality is merely one type of predictable behavior that occurs in computer systems. Systems that exhibit strong locality of reference are great candidates for performance optimization through the use of techniques such as the cache, instruction prefetch technology for memory, or the advanced branch predictor at the pipelining of processors.
