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) A connection that provides the physical transfer of data from one node to another.<br />(2) In a file system, a connection between a directory and an object. The link is established when the object is created.<br />(3) In hypertext, an author-defined association between two information nodes.<br />(4) In SNA, the combination of the link connection (the transmission medium) and two link stations (one at each end of the link connection).<br />(5) In TCP/IP, a term for a communications line. A TCP/IP link may share the use of a communications line with SNA.<br />(6) In a file system, a connection between an i-node and one or more file names associated with it.<br />(7) In data communication, a transmission medium and data link control (DLC) component that together transmit data between adjacent nodes.<br />(8) A line or arrow that connects activities in a process. A link passes information between activities and determines the order in which they run.<br />(9) A directional relationship between two items: the parent and the child. You can use a set of links to model one-to-many associations. See also reference.

(1) A connectivity topology that connects a series of systems or expansion units together. Signals can travel in either direction for optimized performance. Redundancy is provided to each unit by treating the connection as a string when a failure occurs somewhere in the loop.<br />(2) A sequence of instructions performed repeatedly.<br />(3) A closed unidirectional signal path connecting input and output devices to a system.<br />(4) A configuration of devices connected to the fabric by way of a fabric loop port (FL_port) interface card.<br />(5) The physical connection between a pair of device adapters in the ESS. See also device adapter.

(1) A portion of a page set. Each partition corresponds to a single, independently extendable data set. Partitions can be extended to a maximum size of 1, 2, or 4 gigabytes, depending on the number of partitions in the partitioned page set. All partitions of a given page set have the same maximum size.<br />(2) On a personal computer hard disk, one of four possible storage areas of variable size; one may be accessed by DOS and each of the others may be assigned to another operating system.<br />(3) A subset of the active cluster nodes that result from a network failure. Members of a partition maintain connectivity with each other.<br />(4) A logical division of storage on a fixed disk.<br />(5) In VSE, a division of the virtual address area that is available for program execution.<br />(6) In BMS, an addressable subset of a display device's internal resources, consisting of a fixed part of the device's screen, and a fixed part of its internal storage. See also presentation space, viewport.<br />(7) In basic N_UP printing, the division of the medium presentation space into a specified number of equal-sized areas in a manner determined by the current physical medium.<br />(8) In activity diagrams, a rectangular, uniquely named grouping that shows activity nodes and edges that have common characteristics. Partitions provide a view of the behaviors in an activity diagram, but do not affect the control flow or object flow.<br />(9) In architecture, a subset of classifiers or packages at the same level of abstraction. A partition represents a vertical slice through an architecture, whereas a layer represents a horizontal slice.

(1) A positive or negative whole number, or zero.<br />(2) In DB2 for i5/OS, a data type indicating that the data is a binary number with a precision of 31 bits.<br />(3) In COBOL, a numeric constant or a numeric data item that does not include any digit position to the right of the assumed decimal point.
Industry:Software
(1) A predetermined value, attribute, or option that is assumed when no other value is specified. A default value can be defined for column data in DB2 tables by specifying the DEFAULT keyword in an SQL statement that changes data (such as INSERT, UPDATE, and MERGE).<br />(2) A value that is automatically assigned.
Industry:Software
(1) A data element or variable that holds the address of a data object or a function.<br />(2) The symbol shown on a display or window that a user can move with a pointing device, such as a mouse.<br />(3) See reference.
Industry:Software
(1) A program module that transfers remote procedure calls (RPCs) and responses between a client and a server. Stubs perform marshalling, unmarshalling, and data format conversion. Both clients and servers have stubs. The Network Interface Definition Language (NIDL) compiler generates client and server stub code from an interface definition.<br />(2) A small module, link-edited into application code, that locates and transfers control to a larger body of related code.<br />(3) The two types of Remote Procedure Calls (RPCs) that are produced by the compiler when an interface is defined. The application code calls the stub, and the RPC mechanism translates this into a call to the appropriate function on the remote machine.<br />(4) A line in a state table that is only partially displayed.<br />(5) A small program routine that substitutes for a longer, possibly remote, program. For example, a stub might be a program module that transfers procedure calls (RPCs) and responses between a client and a server. In Web services, a stub is an implementation of a Java interface generated from a Web Services Definition Language (WSDL) document.<br />(6) A replica or Notes database copy that has not yet been filled with documents. The database is no longer a stub after the first replication takes place.<br />(7) A component containing functionality for testing purposes. A stub is either a pure "dummy", just returning some predefined values, or it is "simulating" a more complex behavior.<br />(8) A protocol extension procedure that connects with the library but remains outside the library.
Industry:Software
(1) A program that interprets user input and determines what to do with the input.<br />(2) A module used to break down a document into its component parts and to construct a document from its component parts.<br />(3) A program that interprets documents that are added to the enterprise search data store. The parser extracts information from the documents and prepares them for indexing, search, and retrieval.
Industry:Software
(1) A program that lets users look at data but not change it.<br />(2) A client program that initiates requests to a Web server using Hypertext Transfer Protocol (HTTP) and displays the information that the server returns.
Industry:Software
(1) A real number represented by a pair of distinct numerals. The real number is the product of the fractional part, one of the numerals, and a value obtained by raising the implicit floating-point base to a power indicated by the second numeral.<br />(2) Either a 32-bit or 64-bit approximate representation of a real number. In IBM SQL, floating-point numbers do not include decimal floating-point numbers. See also double-precision floating-point number, single-precision floating point number, decimal floating-point number.
