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