(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 disc 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 programmes are run. See also background.<br />(2) In TSO, the environment in which programmes 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.
Industry:Software
(1) An object class that is used for objects that connect different parts of the network and route or switch traffic between these parts. This class includes gateways, repeaters (including multiport repeaters), and bridges. See also network class.<br />(2) Object-oriented programming class that provides standard access to APIs that are native to specific content servers.
Industry:Software
(1) In MVS, a variable-size subdivision of virtual storage that is allocated to a job step or system task. CICS Transaction Server runs in an MVS/ESA region, usually referred to as the CICS region.<br />(2) A physical instance of a CICS server.<br />(3) A contiguous area of virtual storage that has common characteristics and that can be shared between processes.
Industry:Software
(1) Removing a data set control block (DSCB) and releasing its space. A tape data set generally is considered to be deleted when its volume or volumes are made available for reuse or destruction. For both disc and tape, deletion generally also includes removing the data set's entry from the catalogue DSCB.<br />(2) In DFSMShsm, the space management technique of deleting data sets, not managed by the storage management subsystem (SMS), that have not been used for a specified number of days and do not have expiration date protection.
Industry:Software
An Internet Engineering Task Force (IETF) specification for the use of CMIP over a TCP/IP protocol stack.
Industry:Software
(1) An object that contains a list of spooled files to be written to an output device, such as a printer or a diskette. The system-recognized identifier for the object type is *OUTQ.<br />(2) A mechanism that can direct sequence information about ordered products to a printer or a file.
Industry:Software
(1) In networking, the server that converts network names to addresses.<br />(2) In a fibre-channel network, the server that contains the worldwide identifiers (WWIDs) of all addressable nodes on the network.
Industry:Software
(1) Requested reset statistics differ from requested statistics in that the statistics counters are reset to zero. See also interval statistics, requested statistics, unsolicited statistics.<br />(2) In CICS Transaction Server, CICS statistics that the user has asked for by using the appropriate EXEC CICS or CEMT commands, which cause the statistics to be written to the SMF data set immediately.
