Locality of reference, also known as the principle of locality, is a term for the phenomenon in which the same values, or related storage locations, are frequently accessed, depending on the memory accesspattern.
There are two basic types of reference locality – temporal and spatial 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 of Reference in Cache Memory : The locality of reference is implemented to utilize the full benefit of cache memory in computer organization. It indicates that all the instructions referred by the processor are localized in nature.
