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.
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.

Chika Sunquist was appointed Commissioner of the California Department of Real Estate (DRE) by Governor Gavin Newsom on November 28, 2023, and she assumed office on January 3, 2024. [5] Real estate licensing is subject to both the Real Estate Law and the Regulations of the Commissioner, which have the force and effect of law.
On Aug. 17, rules surrounding real estate commissions are set to change thanks to a legal settlement between the National Assn. of Realtors and home sellers. Proponents hope the new rules will ...
Real estate brokerages may get a cut of the commission as well. The brokerage RE/MAX, for example, has a split commission setup by which its agents receive 95 percent of the full commission from ...
Most modern CPUs are so fast that for most program workloads, the bottleneck is the locality of reference of memory accesses and the efficiency of the caching and memory transfer between different levels of the hierarchy [citation needed]. As a result, the CPU spends much of its time idling, waiting for memory I/O to complete.
The most efficient caching algorithm would be to discard information which would not be needed for the longest time; this is known as Bélády's optimal algorithm, optimal replacement policy, or the clairvoyant algorithm. Since it is generally impossible to predict how far in the future information will be needed, this is unfeasible in practice.
Locality of reference of user software has weakened. This is mostly attributed to the spread of object-oriented programming techniques that favor large numbers of small functions, use of sophisticated data structures like trees and hash tables that tend to result in chaotic memory reference patterns, and the advent of garbage collection that ...
