• Advanced Program to Program Communications (APPC) — a Systems Network Architecture (SNA) concept which allows programs running on an SNA network to directly access each other as peers.
• American National Standards Institute (ANSI) — a body of people who, from time to time, establish data representation standards.
• Amplifier - a device spaced at intervals thoughout a network to boost the strength of electronic signals. Sometimes confused with a repeater.
• AppleTalk - a protocol devised by Apple Computer for medium speed but inexpensive networking of Macintosh computer systems.
• Backbone — the main trunk making up a networking system. Signals travel the backbone and then branch to devices. Star topologies do not use backbones.
• Baud — short for Baudot, the individual who first devised a system of data encoding, baud is a measure of the number of changes of state per second on a communications channel (not technically equal to bps, but close).
• Bits Per Second (BPS) — a measure of transmission speed, the number of data bits transmitted during a one second interval of communication time.
• BNC — a type of connector used to connect thin-wire Ethernet.
• Bridge - a device that permits communication between two local-area networks that have similar protocols. Unlike gateways, bridges do not perform protocol conversion.
• Broadband — network communications using signals of the same frequency.
• Carrier Sense Multiple Access/Collision Detection (CSMA/CD) - an access method where communications contention is resolved by collision detection. In Ethernet, any node can transmit at any time; all nodes are continuously listening; if there is a collision, each transmitting nodes waits a random amount of time (therefore different) and re-transmits.
• Cluster Controller — the central element of a terminal system such as the IBM 3270 Information Display System, which concentrates terminal I/O onto a single data channel.
• Coax — short for coaxial cable, a cable made up of a central conductor surrounded by insulation and a braided shielding conductor.
• Collision Avoidance (CA) — a method of avoiding multiple nodes transmitting simultaneously, such as used by the AppleTalk protocol.
• Cyclic Redundancy Check (CRC), or Checksum — a method used to detect when errors have occurred in a transmission.
• DECNet — a network protocol created by Digital Equipment Corporation to interconnect DEC computers.
Ethernet can also be used on fiber-optic and twisted pair cabling. In the case of twisted pair wiring where there is one line for sending and one for receiving, special hardware must be used to provide for collision detection and handle routing.
Ethernet refers to the physical layer of the OSI scheme and many protocols run on top of Ethernet, EtherTalk, DECNet, TCP/IP, et al. Although Ethernet’s top or burst data exchange rate is 10 Mbps, or 40 times the speed of normal AppleTalk, actual throughput on an AppleTalk network will be much less. Users have reported data exchange rates of 1 to 2.4 Mbps.
• EtherTalk — an implementation of AppleTalk designed to work on an Ethernet-based network.
• Gateway - a device that uses protocol conversion to connect dissimilar communications systems. Provides the translation from one set of protocols to another. Gateways differ from bridges since bridges do not perform protocol conversion.
• IEEE 802.3 - a bus structured LAN (Ethernet) based on the CSMA/CD access method.
• IEEE 802.4 - a bus-structured LAN based on the token-passing method.
• IEEE 802.5 - a ring-structured LAN based on the token-passing access method (adopted by IBM).
• Local Area Network (LAN) — A LAN is a group of computers located geographically close together (distances measured in feet), physically and logically connected allowing the transfer of information from point to point.
• LocalTalk — LocalTalk refers to the physical layer, the actual cabling, of an AppleTalk network (layer 1 of the OSI model). Formerly, AppleTalk meant the entire AppleTalk networking system; now, AppleTalk refers only to the networking protocol (layer 7 of the OSI model).
• Open Systems Interconnections (OSI) — a set of networking protocols under development by the International Standards Organization (ISO) which will allow for true, world wide computer networks. The OSI standard is designed to be device independent, operating system independent, and transparent to the network user. The OSI reference model has seven levels:1) Physical; 2) Data Link; 3) Network; 4) Transport; 5) Session; 6) Presentation; 7) Application. AppleTalk complies with the OSI model, with LocalTalk at level 1 and AppleShare at level 7.
• Protocol — a set of rules specifying the formalities of communications. In networking, all devices and programs that follow the rules will be compatible with each other.
• Repeater - a device spaced at intervals thoughout a radio wave-based network to boost the strength of electronic signals. Sometimes confused with an amplifier.
• Systems Network Architecture (SNA) — a communications standard developed by IBM .
• Transmission Control Protocol/Interface Protocol (TCP/IP) — an industry standard protocol suite for open-system networking implementing the middle levels of the ISO model. TCP/IP allows transmitting files between VAXes, SUN, Apollo, and other computers and workstations. Originally developed by the Department of Defense, TCP/IP is the protocol for the very extensive ARPANET system. Because of its wide use, TCP/IP is the default networking standard at the present time. In time, it will be replaced by the OSI model.
• Twisted Pair Wiring — a cable formed by a series of small conductors grouped into pairs and twisted at approximately one turn per foot. The twisting tends to balance the line and offset noise generation, making the cable less subject to interference and therefore more quiet.
• Wide Area Network (WAN) - A WAN is a group of computers separated by long distances (measured in miles), physically and logically connected together allowing the transfer of data from point to point.
