Unformatted text preview: uters built between 1975 and 1989. They used large-scale integrated circuits, semiconductor memories and powerful high-level languages and operating systems. Fourth-Generation Languages (4GLs): Programming languages that require the programmer to specify only "what" to do, not "how" to do it. Frequency Division Multiplexing (FDM): A method used to concurrently transmit data between several transmitters and receivers over a single transmission medium. The available bandwidth of a physical medium is divided into smaller, disjoint logical bandwidths and each of the component bandwidths is used as a separate communications line (channel). Front-end processor: A processor designed specifically to handle the communications processing task. Its main purpose is to off-load communications processing task from the host computer, thereby the host computer can be dedicated for applications and data processing jobs. Full adder: An adder, which adds three binary digits and outputs a result bit and a carry bit. Full duplex: A data transmission mode in which data can be transmitted between a source and a destination in both directions simultaneously. Function: A subprogram that returns a single value. Fuzzy logic: Logic that is based on rough match of attribute values instead of exact matches. The truth values are not a definitive yes or no, on or off kind, but can lie anywhere on the 0.0 to 1.0 interval of real numbers. G Garbage-in-garbage-out (GIGO): Refers to computer errors caused due to incorrect input data or unreliable programs. Gateway: (1) A computer that is connected to the Internet by using a dedicated (leased) telephone line and is used to provide Internet connectivity to other computers via it. (2) An internetworking tool that is used to interconnect dissimilar networks that use different communication protocols. Generation: In computer talk, it is a step in technology. It provides a framework for the growth of the computer industry. Gigabytes: (GB) Memory storage equal to 1,073,741,824 (2 30) bytes in a computer. Gigaflop: 109 floating-point arithmetic operations per second. Google: An Internet...
