  • portability

    Portability is a characteristic attributed to a computer program if it can be used in an operating systems other than the one in which it was created without requiring major rework.

  • file system

    In a computer, a file system (sometimes written filesystem) is the way in which files are named and where they are placed logically for storage and retrieval.

  • SmartMedia card

    A SmartMedia card (originally called a solid-state floppy disk card, or SSFDC) is a memory card developed by Toshiba that uses flash memory to store data and to make it portable among devices, such...

  • dropout

    A dropout is a small loss of data in an audio or video file on tape or disk.

  • FRAM (ferroelectric RAM)

    FRAM (ferroelectric RAM) is random access memory that combines the fast read and write access of dynamic RAM (DRAM) - the most common kind of personal computer memory - with the ability to retain d...

  • Ultra DMA (UDMA or Ultra DMA/33)

    Ultra DMA (UDMA, or, more accurately, Ultra DMA/33) is a protocol for transferring data between a hard disk drive through the computer's data paths (or bus) to the computer's random access memory (...

  • PLEDM (phase-state low electron drive memory)

    PLEDM (phase-state low electron drive memory) is a new memory microchip technology that offers vastly greater capacity than memory devices commonly used in the past.

  • Standard MIDI File (SMF)

    The SMF (Standard MIDI File) was developed to allow musicians and audio file developers to transfer their sequenced MIDI data from one software application to another.

  • WRAM (Window RAM)

    Window RAM (WRAM), unrelated to Microsoft Windows, is very high-performance video RAM that is dual-ported and has about 25% more bandwidth than VRAM but costs less.

  • disk cache

    A disk cache is a mechanism for improving the time it takes to read from or write to a hard disk.

  • Andrew file system (AFS)

    An Andrew file system (AFS) is a location-independent file system that uses a local cache to reduce the workload and increase the performance of a distributed computing environment.

  • thin-film disk

    A thin-film disk is a hard disk storage medium with a very thin coating of a metallic alloy or glass instead of the usual carbon-based material found on other types of hard disks.

  • pipeline burst cache

    A pipeline burst cache is a cache or storage area for a computer processor that is designed to be read from or written to in a pipelining succession of four data transfers (or bursts) in which late...

  • magnetoresistive head technology

    Magnetoresistive (MR) head technology is used in disk drives to allow higher storage densities than the older inductive-head technology.

  • Sound Designer II (SD2)

    SDII (Sound Designer II, sometimes seen abbreviated as SD2) is a monophonic/stereophonic audio file format, originally developed by Digidesign for their Macintosh-based recording/editing products.

  • Jaz drive

    A Jaz drive is a small, portable hard disk drive used primarily for backing up and archiving personal computer files.

  • volume

    In computers, a volume is an identifiable unit of data storage that is sometimes (but not always) physically removable from the computer or storage system.

  • shadow RAM

    Shadow RAM is a copy of Basic Input/Output Operating System (BIOS) routines from read-only memory (ROM) into a special area of random access memory (RAM) so that they can be accessed more quickly.

  • video RAM (VRAM)

    Video RAM (VRAM) means in general all forms of random access memory (RAM) used to store image data for a computer display.

  • hard disk drive (HDD)

    In a personal computer, a hard disk drive (HDD) is the mechanism that controls the positioning, reading, and writing of the hard disk, which furnishes the largest amount of data storage for the PC....
