Temporary computer storage used for quick retrieval of data in order to increase processing speed.
The cached data can be stored in a reserved area of RAM, a special cache chip (separate from the CPU) that provides faster access than RAM, or on the disk drive. By keeping frequently accessed data in a rapidly accessible place, the computer can respond quickly to requests for those data without having to perform time-consuming searches of RAM or hard drives. Since a “stale” cache will contain data that have been superseded by later information, the cached data must be refreshed periodically. 
printer, computer - Electronic device that accepts text files or images from a computer and transfers them to a medium such as paper or film.
cache memory - a supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processor of a computer. The cache augments, and is an extension of, a computer's main memory. Both main memory and cache are internal, random-access memories (RAMs) that use semiconductor-based transistor circuits. Cache holds a copy of only the most frequently used ...

Wasatch Range - segment of the south-central Rocky Mountains, extending southward for about 250 miles (400 km), from the bend of the Bear River in southeastern Idaho, U.S., to beyond Mount Nebo, near Nephi in north-central Utah. It lies east of Great Salt Lake and Salt Lake City and includes the Bear River Range at the northern end. South and east of Salt Lake City are many peaks that surpass 11,000 feet (3,400 ...
San Salvador Island - one of the Galapagos Islands, in the eastern Pacific Ocean about 600 miles (965 km) west of mainland Ecuador. Its relief is dominated by two volcanoes, the larger rising to 1,700 feet (520 m), that form the mass of the island's area of 203 square miles (526 square km). Originally named for England's King James II, who was previously the duke of York, the island was also formerly called York and ...
Malheur River - river rising in the Strawberry Mountain Wilderness on the southern slopes of the Blue Mountains in the Malheur National Forest, Oregon, U.S. It flows southeast, north, and northeast to join the Snake River at Ontario on the Idaho state line, after a course of 165 miles (266 km). Warm Springs Reservoir, impounded by Warm Springs Dam (1919), is on the Middle Fork of the Malheur, north of Riverside. ...
