Sometimes referred to as “Big Blue” IBM is a multinational corporation headquartered in Armonk, New York. It manufactures computer hardware and software and provides information technology and services.
(1) In Ada programming, a discrete unit that performs a specific task or set of tasks. Program units are subroutines and calling programs that are assembled separately and then linked to make a complete program.<br />(2) See compilation unit.
Industry:Software
(1) In telephony, circuits that connect two switching systems, as opposed to connecting a customer line to a switching system.<br />(2) In the CVS team development environment, the main stream of development, also referred to as the HEAD stream.<br />(3) A telephone connection between two central offices or switching devices. In DirectTalk, a trunk refers to 24 or 30 channels carried on the same T1 or E1 digital interface. See also channel.
Industry:Software
(1) A virtual circuit that is requested by a virtual call. It is released when the virtual circuit is cleared.<br />(2) In OSI, a temporary association between two DTEs that is initiated when one DTE makes a call request to the network.
Industry:Software
(1) In CICS/VSE, a range of up to two gigabytes of contiguous virtual storage addresses that a program can use as workspace. Although the virtual disk exists in storage, it appears as a real FBA disk device to the user program. All I/O operations directed to a virtual disk are intercepted and the data to be written to, or read from, the disk is moved to or from a data space. Like a data space, a virtual disk can hold only user data; it does not contain shared areas, system data or programs. Unlike an address space or a data space, data is not directly addressable on a virtual disk. To manipulate data on a virtual disk, the program has to perform I/O operations.<br />(2) A device that host systems attached to the storage area network (SAN) recognize as a Small Computer System Interface (SCSI) disk.
Industry:Software
(1) In the Secure Sockets Layer (SSL), the public key and associated distinguished name of a certificate authority (CA).<br />(2) A certificate authority's certificate merged into the Domino Directory, client's browser, or the server's key ring file, which allows clients and servers to communicate with any client or server that has that certificate authority's certificate marked as trusted.
Industry:Software
(1) A type of merchandising association in which a suggested product is chosen as an addition to the currently displayed or selected product. See also cross-sell, merchandising association, up-sell.<br />(2) An IBM designation for a separately orderable part that has no type number, is for purchase only, and does not receive normal IBM maintenance.
Industry:Software
(1) In advanced program-to-program communications, the amount of processing that is started directly or indirectly by a program on the source system. See also unit of recovery.<br />(2) A recoverable sequence of operations performed by an application between two points of consistency. A unit of work begins when a transaction starts or at a user-requested syncpoint. It ends either at a user-requested syncpoint or at the end of a transaction.<br />(3) For IMS DB, all of the input and output messages associated with a transaction. For IMS TM, a single IMS message. For CQS, a client-defined grouping of data objects.<br />(4) A recoverable sequence of operations within an application process. At any time, an application process is a single UOW, but the life of an application process can involve many UOWs as a result of commit or rollback operations. In a multisite update operation, a single UOW can include several units of recovery. See also multisite update, unit of recovery, remote unit of work, transaction.
Industry:Software
(1) In the Backup, Recovery, and Media Services licensed program, a named or otherwise identifiable set of controls used by Backup, Recovery, and Media Services to manage and control specific operations. A policy is an overriding value that is carried in tables for use as a default in processing backup, recovery, archive, and media management operations.<br />(2) In QoS, the combination of rules and services. The rules define the criteria for traffic treatment, network resource access, and use.<br />(3) A set of considerations that influence the behavior of a managed resource or a user. See also policy expression.<br />(4) A list of file-placement and service-class rules that define characteristics and placement of files. Several policies can be defined within the configuration, but only one policy set is active at one time. See also file-placement rule, file-management policy, file-placement policy.<br />(5) A document that sets forth high-level statements of how changes, releases, or other processes are to be managed, organized, and performed.
Industry:Software
(1) A virtual private network (VPN) connection that automatically refreshes the keys that keep data secure. A dynamic connection also contains proposals that allow the key server to negotiate which parameters to use with the remote key server. See also manual connection.<br />(2) A connection created at the time of sign-on or using the network connection control (NCC) record sent from another node.
Industry:Software
(1) In CICS/VSE, a subdivision of the virtual address area available to the user for the allocation of private, nonshared partitions.<br />(2) In virtual storage systems, the virtual storage assigned to a job, terminal user, or system task. See also address space.
