CACHE (Anthromorphemics)

A deliberate store of equipment, food, furs or other resources placed in, or on the ground (perhaps protected by a rock cairn), or raised above the ground on a platform.

CACHE (Anthropology)

A deliberate store of equipment, food, furs or other resources placed in, or on the ground (perhaps protected by a rock cairn), or raised above the ground on a platform.

CACHE (Business Intelligence)

Pronounced "cash." The storage of recently visited sites and data which can be accessed from computer memory instead of linking the server each time you return to the site. This speeds the access time, but does not reflect any changes to the site while in the cache. On rapidly changing sites you may need to click the reload button in order to read the most recent changes.

CACHE (Children, Early Years Acronyms)

CACHE (Computer Hardware)

Pronounced cash, a special high-speed storage mechanism. It can be either a reserved section of main memory or an independent high-speed storage device. Two types of caching are commonly used in personal computers: memory caching and disk caching. A memory cache, sometimes called a cache store or RAM cache, is a portion of memory made of high-speed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM) used for main memory. Memory caching is effective because most programs access the same data or instructions over and over. By keeping as much of this information as possible in SRAM, the computer avoids accessing the slower DRAM. Some memory caches are built into the architecture of microprocessors. The Intel 80486 microprocessor, for example, contains an 8K memory cache, and the Pentium has a 16K cache. Such internal caches are often called Level 1 (L1) caches. Most modern PCs also come with external cache memory, called Level 2 (L2) caches. These caches sit between the CPU and the DRAM. Like L1 caches, L2 caches are composed of SRAM but they are much larger. Disk caching works under the same principle as memory caching, but instead of using high-speed SRAM, a disk cache uses conventional main memory. The most recently accessed data from the disk (as well as adjacent sectors) is stored in a memory buffer. When a program needs to access data from the disk, it first checks the disk cache to see if the data is there. Disk caching can dramatically improve the performance of applications, because accessing a byte of data in RAM can be thousands of times faster than accessing a byte on a hard disk. When data is found in the cache, it is called a cache hit, and the effectiveness of a cache is judged by its hit rate. Many cache systems use a technique known as smart caching, in which the system can recognize certain types of frequently used data. The strategies for determining which information should be kept in the cache constitute some of the more interesting problems in computer science.

CACHE (Computer Technology)

Refers to a location where temporary or often used data is stored.

CACHE (DTV)

Storage of digital data (video, audio, text, etc.).

CACHE (Data Recovery)

High-speed RAM used as a buffer between the CPU and a hard drive. The cache retains recently accessed information to speed up subsequent accesses to the same data. When data is read from or written to disk, a copy is saved in the cache, along with the associated disk address. The cache monitors the addresses of subsequent read operations to see if the required data is already in the cache. If it is, the drive returns the data immediately. If it is not in the cache, then it is fetched from the disk and saved in the cache.

CACHE (Digital Imaging)

A temporary storage area for information which locates itself between the hard disk and the RAM by employing intuitive logic. It also speeds up the access time of the data.

CACHE (Ecology)

A pile of food hidden away for Winter. Some squirrels and birds cache nuts and seeds to get them through cold weather.

CACHE (Hard Drive Recovery)

High-speed RAM used as a buffer between the CPU and a hard drive. The cache retains recently accessed information to speed up subsequent accesses to the same data. When data is read from or written to disk, a copy is saved in the cache, along with the associated disk address. The cache monitors the addresses of subsequent read operations to see if the required data is already in the cache. If it is, the drive returns the data immediately. If it is not in the cache, then it is fetched from the disk and saved in the cache.

CACHE (Interactive Marketing)

Memory used to temporarily store the most frequently requested content/files/pages in order to speed its delivery to the user. Cache can be local (i.e. on a browser) or on a network. In the case of local cache, most computers have both memory (RAM), and disk (hard drive) cache. Today, Web browsers cause virtually all data viewed to be cached on a user's computer.

CACHE (Internet)

In browsers, "cache" is used to identify a space where web pages you have visited are stored in your computer. A copy of documents you retrieve is stored in cache. When you use GO, BACK, or any other means to revisit a document, the browser first checks to see if it is in cache and will retrieve it from there because it is much faster than retrieving it from the server.

CACHE (Laptop)

Portion of a processor that holds recently accessed data. It is designed to speed up the subsequent accesses to the same data. When data is read the first time, a copy is saved in the cache, along with its address. The cache is normally constructed with faster memory chips than those in the main memory, so that data returned from the cache is delivered faster than from the main memory.

CACHE (Linux, Red Hat)

A temporary storage area for currently-used or recently-accessed data. Cache can be system-level (residing in dedicated cache memory on the motherboard or physically etched on the central processing unit) or disk-based (residing in main memory such as a hard disk drive or RAM).

CACHE (Photography)

A temporary storage area for information which locates itself between the hard disk and the RAM by employing intuitive logic. It also speeds up access time of the data.

CACHE (RAID Drive Recovery)

High-speed RAM used as a buffer between the CPU and a hard drive. The cache retains recently accessed information to speed up subsequent accesses to the same data. When data is read from or written to disk, a copy is saved in the cache, along with the associated disk address. The cache monitors the addresses of subsequent read operations to see if the required data is already in the cache. If it is, the drive returns the data immediately. If it is not in the cache, then it is fetched from the disk and saved in the cache.

CACHE (Storage Media)

Specialized RAM used to optimize data transfers between system elements with different performance characteristics, e.g., disk to main memory or main memory to CPU.

CACHE (Technology)

"Cache" means "storage place". An Internet browser cache is a method to temporarily store the information on a page in your computer. If you request a page (or part of a page, e.g. an image) that is stored in your cache, Web browsers can retrieve the page from your cache more quickly than retrieving the page again from it's location on the Internet. Sometimes you may not want a page to be retrieved from a cache. The page you viewed initially may no longer be identical to the page currently offered by the network. If a modification to a particular URL has occurred, you may want to view the updated page rather than the copy (now stale) stored in your cache. You can modify your cache preferences in Netscape under Edit > Preferences > Advanced > Cache. In Internet Explorer go to View > Internet Options > Temporary Internet Files > Settings.

CACHE (Usability)

A copy of visited web pages, stored on a user's computer. Depending on system settings, the cache can hold copies of pages viewed many days prior. When making changes to a page, it is sometimes necessary to "reload" the page, in order to erase the cache, and see the new version. Web pages can be set to force a reload, though this does not always work on all browsers.
