In computer science, locality of reference, also known as the principle of locality, [1] is the tendency of a processor to access the same set of memory locations repetitively over a short period of time. [2] There are two basic types of reference locality – temporal and spatial locality.
The simplest locality model is no locality: instantaneous action at a distance with no limits for relativity. The locality model for action at a distance is called continuous action. [2] The gray area (a circle here) is a mathematical concept called a "screen".
In computing, a memory access pattern or IO access pattern is the pattern with which a system or program reads and writes memory on secondary storage.These patterns differ in the level of locality of reference and drastically affect cache performance, [1] and also have implications for the approach to parallelism [2] [3] and distribution of workload in shared memory systems. [4]
The main hurdle in implementing the working set model is keeping track of the working set. The working set window is a moving window. At each memory reference a new reference appears at one end and the oldest reference drops off the other end. A page is in the working set if it is referenced in the working set window.
Locality of Reference also applies to other kinds of resources, such as web pages and even parking spaces. The topic of memory locality is a subset of the broader topic of locality of reference. - Rrcjab 23:44, 3 March 2007 (UTC) It seemed pretty clear to me that nobody supports merging "Locality of reference" into "Memory locality".
Locality may refer to: Locality, a historical named location or place in Canada; Locality (association), an association of community regeneration organizations in England; Locality (linguistics) Locality (settlement) Suburbs and localities (Australia), in which a locality is a geographic subdivision in rural areas of Australia

In art, a reference is an item from which a work is based. This may include: an existing artwork; a reproduction (i.e., a photo) a directly observed object (e.g., a person) the artist's memory; Another example of reference is samples of various musical works being incorporated into a new one.
