locality of reference

In computer science, locality of reference, also called the principle of locality, is the term applied to situations where the same value or related storage locations are frequently accessed. There are three basic types of locality of reference: temporal, spatial and sequential:Temporal localityHere a resource that is referenced at one point in time is referenced again soon afterwards. Spatial localityHere the likelihood of referencing a storage location is greater if a storage location near it has been recently referenced.Sequential localityHere storage is accessed sequentially, in descending or ascending order.
