Storage Technology Definitions

  • B

    BEDO DRAM (Burst Extended Data Output DRAM)

    BEDO DRAM (Burst Extended Data Output DRAM) is a type of dynamic random access memory (DRAM) that can send data back to the computer from one read operation at the same time it is reading in the address of the next data to be sent.

  • bit padding

    Bit padding is the addition of one or more extra bits to a transmission or storage unit to make it conform to a standard size.

  • bit rot

    Bit rot is the slow deterioration in the performance and integrity of data stored on storage media. It is also known by the names bit decay, data rot, data decay and silent corruption.

  • block storage

    Block storage is a type of data storage typically used in storage-area network (SAN) environments where data is stored in volumes, also referred to as blocks.

  • Blue Book

    The Blue Book is the informal name for the standard specification document for stamped multisession (also known as the enhanced CD or E-CD) disk format, developed in 1995 from a supplement to Philips and Sony's 1988 Orange Book.

  • brontobyte

    A brontobyte is a measure of memory or data storage that is equal to 10 to the 27th power of bytes.

  • buffer credits or buffer-to-buffer credits (BBCs)

    Buffer credits, also called buffer-to-buffer credits (BBCs), allow data communication in a Fibre Channelstorage area network (SAN) where there are long spans of fiber opticcable.

  • buffer flush

    A buffer flush is the transfer of computer data from a temporary storage area to the computer's permanent memory.

  • bus

    In a computer or on a network, a bus is a transmission path on which signals are dropped off or picked up at every device attached to the line.

  • business impact analysis (BIA)

    A business impact analysis (BIA) identifies and examines the effects of natural or human-caused disasters on critical business functions.

  • byte

    In most computer systems, a byte is a unit of data that is eight binary digits long. Bytes are often used to represent a character such as a letter, number or typographic symbol.

  • C

    cache (computing)

    Definition: Learn what cache is and how it’s used to shorten data access times, reduce latency and improve input/output (I/O).

  • cache algorithm

    A cache algorithm is a detailed list of instructions that decides which items should be discarded in a computer's cache of information.

  • cache memory

    Cache memory, also called CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM.

  • capacity optimization (CO)

    Capacity optimization (CO) is a technique for getting more data on a storage medium by analyzing the data for unique repetitive patterns that can be stored as and reassembled from shorter symbols.
