Protocols Standards or rules that allow computers to communicate. Novell IPX/SPX, UNIX TCP/IP, DECnet, Microsoft NetBEUI, and Macintosh AppleTalk are all examples of protocols AppleTalk A protocol for networking Macintosh computers. TCP/IP - Transmission Control Protocol/Internet Protocol - The protocol that the internet observes. All internet browsers operate under TCP/IP rules. IP Address A 4-byte address, with each byte separated by a ".". Example: 146.69.140.1. Telnet A remote terminal session--a communication channel between two devices. Ethernet Address A 6-byte address, which refers to the network hardware device, for example, a NIC. This is also known as a MAC (Media Access Control) address. Each byte is separated by a '-' when used in a PC command. Example: 00-C0-E2-00-21-43. Each byte is separated by a ':' when used in a UNIX command. Example: 00:c0:e2:00:21:43. DHCP Server - Dynamic Host Configuration Protocol - A server that automatically provides IP addresses for appropriately configured nodes at boot up.
Media The physical carrier of information in networks. Media may be wiring, fiber, or air. Daisy-chain Connecting one unit to the next, in series. If any unit is taken off the chain, communication to all other units is disrupted. Coaxial Cable An inner conductor surrounded by shield which acts as the return conductor. The shield is typically grounded at the BNC connector. Thinnet Thin coaxial wire used on 10Base2 networks RJ-58 A/U Cable Coaxial cable used in 10Base2 (Thinnet) networks. Thicknet Thickwire coaxial wire used on 10Base5 networks. Unshielded Twist Pair (UTP) Cable used on 10Base-T, 100Base-TX, and EtherTalk networks Category 5 Cable Consists of 4 twisted-pair wires which can handle 10- and 100Mbps transmission rates BNC Connector A barrel-like connector used on thin coaxial cable RJ-45 Connector An 8-wire connector used on UTP cable RJ-11 Connector A 4-wire connector used on phone cable
Ethernet Standard defining how to physically connect devices on the network and transfer data at 10Mbps. It can run on thick coax, thin coax, or twisted pair wiring. Fast Ethernet IEEE standard that defines the data transfer rate at 100Mbps 10Base-T 10Mbps transmission running on unshielded twisted pair wires 100Base-TX 100Mbps transmission through unshielded twisted pair wires UTP Unshielded Twisted Pair another name for 10Base-T or 100Base-TX cable 10Base2 10Mbps transmission through thin coax cable 10Base5 10Mbps transmission though thickwire EtherTalk AppleTalk running over Ethernet SQE Signal Quality Test for Ethernet. Frequently called "heartbeat"\
General Networking Terms IEEE Institue of Electrical and Electronics Engineers. An organization that maintains the standards for 10Base-T (Ethernet) and other communications standards. Network A collection of computers, printers, scanners, and other devices which communicate over a shared medium Node An active device on a network Topology The arrangement of nodes that comprise the network. Types include star, ring, bus, and tree. Bus A network topology in which all nodes are connected to a single wire. All nodes receive all transmissions Computer Bus A collection of address, data, and control signals in the computer. The NIC is attach to the bus Mbps - Megabits per second - 1 million bits per second kbps - Kilobits per second - 1000 bits per second Physical Address An address identifying a single node. This is also known as a MAC (Media Access Control) Address. Packet A series of bits containing data and control information, such as source and destination address, format, checksum value, etc. Spool File - Simultaneous Print Operation OffLine - A temporary file written to a disk, then transferred to the printer at a later time.
Network Devices AUI - Attachment Unit Interface - A device which connects the 10Base5 NIC connector to the network AAUI - Apple Attachment Unit Interface - An EtherTalk connection. Physically smaller than an AUI connector. Transceiver A device that connects a node to various types of media NIC - Network Interface Card - A card that is installed on the computers bus system for communicating with the network Hub - A device that provides for multiple 10Base-T or 100Base-TX connections. NVRAM - Non-Volatile RAM - Memory for storing configuration parameters. The settings are not lost when the unit is power cycled. L-COM Adapter A device that is used with a standard Ethernet cable to provide a cross-over connection.
