Glossarypage 62LaCie Big DiskUser’s ManualGlossaryAsynchronous – Data transfer method where the data is transferred independently of other processes. With this transfermethod, the intervals between transmissions can vary, and data can be resent if it is initially missed.Backup – (1) The act of creating at least one additional copy of data onto a different (and safe) storage device from where itcan be retrieved at a later time if needed. (2) A copy of a file, directory, or volume on a separate storage device from theoriginal, for the purposes of retrieval in case the original is erased, damaged, or destroyed.Bit – The smallest measure of computerized data, either a 1 or a 0. Eightbits equal one byte, or one character.Block – A very small section of the storage media comprised of one or more sectors. A block is the smallest amount of spaceallocated on a drive for data storage. By default, a sector of data consists of 512 bytes.Buffer – RAM cache that is faster than the data that is being delivered. Buffers are used so data may be stored and deliveredto the receiving item as it is needed.Bus – Electronic links that enable data to flow between the processor, RAM and extension cables (peripherals).Byte – A sequence of adjacent binary digits, or bits, considered as a unit, 8 bits in length. There are 8 bits in 1 byte. See alsoMB (Megabyte) or GB (Gigabyte).Cache, -ing – This is an area of electronic storage (usually RAM) set aside to store frequently used data from electro-mechanical storage (hard drives, floppy disks, CD/DVD-ROM, tape cartridges, etc.) Therefore, storing frequently used data inRAM can enhance your system’s overall response to disk-intensive operations significantly.Configuration – When talking about a PC, configuration is understood to be the sum of the internal and external componentsof the system, including memory, disk drives, the keyboard, the video subsystem and other peripherals, such as the mouse,modem or printer. The configuration also implies software: the operating system and various device managers (drivers), aswell as hardware settings and options set by the user via configuration files.Controller – This is a component or an electronic card (referred to in this case as a "controller card," such as PCI or PCMCIAcards) that enables a computer to communicate with or manage certain peripherals. The controller manages the operation ofthe peripheral associated with it, and links the PC bus to the peripheral via a ribbon cable inside the PC. An externalcontroller is an expansion card which fills one of the free slots inside your PC and which enables a peripheral (CD-ROMdrive, scanner or printer, for instance) to be connected to the computer.Cross-platform – Term that refers to a device that is able to be operated by both Mac and Windows operating systems.Data Stream – The flow of data that accomplishes a task, usually related to moving data from storage to computer RAM orbetween storage devices. |
