--:::::Networking Acronyms and Terminology::::-- This is a list of basic computer networking acronyms and terminology. It is a first draft and I will continue to update it and add more information and terms. LAN- Local Area Network usually a single building or campus WAN- Connects lans up to global in scale (internet) MAN- Metro area network City Wide Network SAN Data storage network PAN Devices around a persons work area, PDA Keybord mouse. NIC- Network interface card NOS- Network operating system- windows server, linux, unix netware Terminator- resistive load at the end of the network cable that blocks reflection and reduces noise Repeater- network amplifier repeats all incoming packets as broadcast to all connections Bridge- connects two similar networks Gateway- connects two dissimilar networks Router- same as gateway but only for routeable protocols can also direct network traffic. B router- router only able to support a single protocol Hub- network splitter, broadcasts all incoming packets to all ports Passive- no active componenets splits signal to all ports, only one per segment, terminate unused ports Active- powered hub amplifies signal while broadcasting to all ports. Switch Splits network and provides and provides direction to network packets Node device that connects to network NAS Network attached storage Collision Detecion and Avoidance -CSMA/CA -Carrier Sense Multiple Access/Collision Avoidance -Node checks network for other broadcasts before transmitting -CSMA/CD -Carrier Sense Multiple Access/Collision Detection -Node broadcasts and waits for reply or time out Token passing -Only the node with an empty token can broadcast -Every node handles every token -Time sharing ensures every node gets equal time MAU -Multistation Access Unit, Allows devices to attach to token ring network Network Administrator -Responsible for maintaining network hardware, software, and users. IPX- Internet Packet eXchange ISP-Internet Service Provider UNC -Universal Naming Convention POTS -Plain Old Telephone Service TCP/IP-Transmission Control Protocol/Internet Protocol SLIP-Serial Line Internet Protocol PPP-Point-to-Point Protocol DUN- Dial Up Network UTP -Unshielded Twisted Pair STP- Shielded Twisted Pair or Spanning Tree Protocol Protocol -Set of rules telling devices on network how to communicate Topology- Physical and logical layout of network VLAN- virtual local area network DHCP – Dynamic Host Configuration Protocol VPN – virtual private network SSL – secure sockets layer
