80 G LOSSARYinteroperabilityThe ability of computer equipment from one vendorto communicate and exchange information withequipment from other vendors.IP addressInternet Protocol address. A unique identifier for amachine that is attached to a network that is madeup of two or more interconnected local area or widearea networks.LANLocal Area Network. A data communications networkthat spans a limited geographical area, such as asingle building or campus. It provides communicationbetween computers and peripherals. LANs have smallgeographical size, high data rate, and low error rate.Layer 2Data-link layer of the OSI Reference Model. Definesthe rules for sending and receiving data across thephysical connection between two systems.Layer 3Network layer of the OSI Reference Model. Definesprotocols for routing data by opening andmaintaining a path on the network between systemsto ensure that data arrives at the correct destinationnode.LEDLight emitting diode. Semiconductor device thatemits light produced by converting electrical energy.Status lights on hardware devices are typically LEDs.load-sharingThe ability of a router to distribute traffic over all itsnetwork ports that are the same distance from thedestination address. Good load-balancing algorithmsuse both line speed and reliability information. Loadbalancing increases the utilization of networksegments, thus increasing effective networkbandwidth.local managementLocal management of a network device via aconnected terminal.MIBManagement Information Base. A database ofnetwork management information that describes thespecifics of individual network components.MLANHigh speed management busses that provideintermodule communication and network andnetwork connectivity to the SMC (SystemManagement Component).MMFMulti-mode fiber. An optical fiber with a corediameter of from 50 to 100 microns. It is the mostcommonly used optical fiber for short distances suchas LANs. Light can enter the core at different angles,making it easier to connect the light source. However,light rays bounce around within the core causingsome distortion and providing less bandwidth thansinglemode fiber.
