A set of nodes and their interconnecting links providing the primary data path across a network .... A backbone may be configured as a bus or as a ring; (2) in a wide area network, a high-speed link to which nodes or data switching exchanges are connected. [IBM]
Refers to a system designed to leave a marker in an application or presentation to which the system will return when the program is next executed.
A functional unit that interconnects two local area networks that use the same logical link control protocol but may use different access control protocols. [IBM]
In communications, pertaining to transmission facilities whose bandwidth is greater than that available on voice grade circuits and therefore capable of high-speed data transmission. [L&S]
A program used to scan and search electronic files.
A set of files, stored on a computer, that may be accessed by any user with a terminal and that is controlled by a systems operator, who organizes the files into topical areas. Files are uploaded and downloaded by users, and most bulletin boards allow users to exchange electronic mail. Computer suppliers often maintain a bulletin board to allow users to have access to information system updates and to report on problems encountered. [D]
(1) A special-purpose buffer storage, smaller and faster than main storage, used to hold a copy of instructions and data obtained from main storage and likely to be needed next by the processor; (2) a buffer storage that contains frequently accessed instructions and data; it is used to reduce access time; (3) an optional part of the directory database in network nodes where frequently used directory information may be stored to speed directory searches. [IBM]
A network system designed to share substantial resources that cannot be provided on every user's machine. The requesting program (client) sends a request to a program at another site (server) and awaits a response.
(1) With respect to computer programs, the result of the implementation of a compiler program used to make a high-language program operable in a computer; (2) the result of aggregating several documents or files. [C]
The invisible, intangible world of electronic information and processes stored at multiple interconnected sites, with controlled access and manifold possibilities for interaction.
Scientific or technical measurements, values calculated therefrom, and observations or facts that can be represented by numbers, tables, graphs, models, text, or symbols and that are used as a basis for reasoning or further calculation.[C]
