(1) An instruction in a program or procedure.<br />(2) In programming languages, a language construct that represents a step in a sequence of actions or a set of declarations.
Industry:Software
(1) Pertaining to the operation of a functional unit or device that is under the control of the system or of a host. See also offline.<br />(2) Pertaining to a user's access to a computer by way of a terminal.
Industry:Software
(1) Pertaining to the portion of recorded information that can be heard.<br />(2) The sound portion of a video signal.
Industry:Software
(1) An internal computer component capable of storing a specified amount of data and accepting or transferring this data rapidly.<br />(2) In the hierarchical file system, to make an underlying file system and the specific functions it supports known to the application programming interface layer and accessible to user applications.<br />(3) To insert authorization and authentication information into binding information.<br />(4) In SQL replication, to define a DB2 table, view, or nickname as a replication source.<br />(5) To add a user-written condition handler onto a routine's stack frame.
Industry:Software
(1) Pertaining to the shared use of resources by multiple interactive users or application programs at the same time.<br />(2) Pertaining to the occurrence of two or more activities within a given interval of time. Concurrent processes can alternately use shared common resources.
Industry:Software
(1) Pertaining to two or more processes that depend upon the occurrences of specific events, such as a common timing signal. See also asynchronous.<br />(2) Occurring with a regular or predictable time relationship.<br />(3) In cross-site mirroring, pertaining to the mode of geographic mirroring where the program that issues the update waits until the operation is completed on both the production copy and the mirror copy. This mode ensures that once control is returned to the client, the operation is accurately reflected on both the production copy and the mirror copy.
Industry:Software
(1) An internal program that reads jobs from an input device or a database file and places them on a job queue.<br />(2) In RJE, a program that reads jobs from a database file or interactive display station and sends them to the host system.
Industry:Software
(1) An Internet Protocol (IP) datagram that contains only a portion of the user data from a larger IP datagram.<br />(2) The smallest unit of file system disk space allocation. A fragment can be 512, 1024, 2048, or 4096 bytes in size. The fragment size is defined when a file system is created.<br />(3) The space allocated for an amount of data too small to require a full block. A fragment consists of one or more subblocks.
Industry:Software
(1) In multiprogramming, the environment in which high-priority programs are run. See also background.<br />(2) In TSO, the environment in which programs are swapped in and out of main storage to allow terminal users to share processing time.
Industry:Software
(1) Proprietary code that is usually delivered as microcode as part of an operating system. Firmware is more efficient than software loaded from an alterable medium and more adaptable to change than pure hardware circuitry. An example of firmware is the Basic Input/Output System (BIOS) in read-only memory (ROM) on a PC system board.<br />(2) An ordered set of microcode instructions and data stored in a hardware EPROM. When microcode software is installed in a hardware EPROM, it becomes firmware. Firmware cannot be modified by the user but can be updated by service personnel. See also microcode.
