Disk cache is hard disk-based memory used to store accessed Web pages. It enables the browser load the stored pages from the cache rather than from the network.
A disk cache is a software technique of speeding data access times. Copies of recently accessed disk sectors are stored in memory to a reserved area called cache RAM. When the executing program or the operating system requests to read a sector from the disk, the disk caching software checks to see if the sector is stored in cache RAM. If it is, the sector is retrieved from RAM and returned; no disk access is required. If the desired sector is not in cache RAM, the software reads the requested sector from the disk, stores it in cache RAM, and returns it to the program. When the info is found in the cache, it's a hit. When the info must be retrieved from the disk, it's a miss. Some disk caching programs also check for sector writes.
An area of computer memory where datat is temporarily stored on its way to or from a disk. A disk cache program can significantly speed up most disk operations. DOS contains the disk cache driver SMARTDRV.SYS, and OS/2 provides CACHE if you are using the high performance file system, or DISKCACHE if you are using the file allocation table system. Disk cache programs are also available from other third party sources.
A program that sets aside a portion of memory to hold the information most recently read from a disk. Memory is much faster than a disk drive. If a program repeatedly requests the same information, a disk cache can considerably improve the system performance. See also SRAM cache.
a cache that stores copies of frequently used disk sectors in random access memory (RAM) so they can be read without accessing the slower disk
a good idea to keep (although I don't how you'd be using one without a memory manager without really killing your memory)
a mechanism for improving the time it takes to read from or write to a hard disk - Contributed by Eagle Domain Names - A name given to a host computer on the Internet
an area of memory that is set aside to cache (store) the data most recently read from the hard disk
an area of RAM memory used to store data accessed frequently from disk
an area of the hard drive, which is reserved to process data
an area set aside on the hard disk or in RAM that holds data recently read from the hard disk, so that it can be accessed quickly if needed again
a program to speed up disk access by storing the most frequently use information in the computer's memory and reading ahead from the disk in anticipation
a section of memory on the disk controller board that bridges the disk and the CPU
a small specialized section of Macintosh RAM set aside to hold a copy of the most recent data read from disk (or volume) into memory
A portion of memory on the PC motherboard or on a drive interface card or controller which is used to store frequently accessed information from the drive, such as the File Allocation Table [FAT] or directory structure, in order to speed up disk access. With a large disk cache, additional data from the data portion of a drive can be cached as well.
A dedicated part of RAM used to store additional data adjacent to data retrieved during a disk fetch to improve system performance.
A disk cache can be viewed as an intermediate "relay station" between client applications and an HSM. It decouples the potentially slow network transfer (to and from client machines) from the fast storage media I/O in order to keep the HSM from bogging down. See dCache.
a temporary storage area on a computer that keeps a copy of Web pages accessed during an online session; a computer can "pull up" the cached version more quickly than retrieving a fresh version from the network
The area in your computer's hard drive where information you accessed while online is kept.
A portion of a computer's random access memory (RAM) set aside for temporarily holding information read from disk. A disk cache does not hold entire files, as does a RAM disk (a portion of memory that acts as if it were a disk drive). Instead, a disk cache is used to hold information that either has recently been requested from disk or has previously been written to disk. If the required information remains in a disk cache, access time is considerably faster than if the program must wait for the disk drive mechanism to fetch the information from disk.
A disk cache is a mechanism for improving the time it takes to read from or write to a hard disk. Today, the disk cache is usually included as part of the hard disk. A disk cache can also be a specified portion of random access memory (RAM). The disk cache holds data that has recently been read and, in some cases, adjacent data areas that are likely to be accessed next. Write caching is also provided with some disk caches.
A section of RAM that provides a cache between the disk and the CPU. It enables the computer to operate faster. Retrieving data from hard disk can be slow; a disk caching program helps solve this problem by placing recently accessed data in the disk cache. Next time that data is needed, it may already be available in the disk cache; otherwise a time-consuming search of the hard disk is necessary.
A portion of RAM used to speed up access to data on a disk. The RAM can be part of the disk drive itself or it can be general-purpose RAM in the computer that is reserved for use by the disk drive
A reserved portion of memory that acts as a buffer between the CPU and a disk. The use of disk cache may significantly expedite data retrieval.
The disk cache in a hard drive, is a relatively small amount of memory that is used to store recently accessed data, or data that is likely to be accessed next. The point of the disk cache is to improve hard drive performance by reducing the amount of time needed to access certain data.
A portion of a computer's RAM set aside for temporarily holding information read from a disk. The disk cache does not hold entire files as does a RAM disk, but information that has either been recently requested from a disk or has previously been written to a disk.
A portion of RAM set aside for temporarily holding information read from a disk. It often makes data retrieval faster.
Portion of memory that a processor uses to store frequently accessed items, which speeds disk access time. When a program needs data, instructions, or information, the processor checks the disk cache. If the item is in disk cache, the processor uses that item and completes the process. If the processor does not find the requested item in the disk cache, then the processor must wait for the hard disk drive to locate and transfer the item from the disk to the processor. 7.12
