Network Glossary

Access Point - A device that allowswireless-equippedcomputers and other devices to communicate with a wired network. also used to expand the range of a wireless network.

Ad-hoc - A group of wireless devices communicating directly with each other(peer-to-peer)without the use of an access point.

AES (AdvancedEncryptionStandard) - A security method that uses symmetric128-bitblock data encryption.

Bandwidth - The transmission capacity of a given device or network.

Bit - A binary digit.

Boot - To start a device and cause it to start executing instructions.

Broadband - Analways-on,fast Internet connection.

Browser - An application program that provides a way to look at and interact with all the information on the World Wide Web.

Cable Modem - A device that connects a computer to the cable television network, which in turn connects to the Internet.

Daisy Chain - A method used to connect devices in a series, one after the other.

DDNS (DynamicDomainNameSystem) - Allows the hosting of a website, FTP server, ore-mailserver with a fixed domain name (e.g., www.xyz.com) and a dynamic IP address.

Default Gateway - A device that forwards Internet traffic from your local area network.

DHCP (DynamicHostConfigurationProtocol) - A networking protocol that allows administrators to assign temporary IP addresses to network computers by “leasing” an IP address to a user for a limited amount of time, instead of assigning permanent IP addresses.

DMZ (DemilitarizedZone) - Removes the Router's firewall protection from one PC, allowing it to be “seen” from the Internet.

DNS (DomainNameServer) - The IP address of your ISP's server, which translates the names of websites into IP addresses.

Domain - A specific name for a network of computers.

Download - To receive a file transmitted over a network.

DSL (DigitalSubscriberLine) - Analways-onbroadband connection over traditional phone lines.

Dynamic IP Address - A temporary IP address assigned by a DHCP server.

EAP (ExtensibleAuthenticationProtocol) - A general authentication protocol used to control network access. Many specific authentication methods work within this framework.

Encryption - Encoding data transmitted in a network.

Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium.

37

Firewall - A set of related programs located at a network gateway server that protects the resources of a network from users from other networks.

Firmware - The programming code that runs a networking device.

FTP (FileTransferProtocol) - A protocol used to transfer files over a TCP/IP network.

Full Duplex - The ability of a networking device to receive and transmit data simultaneously.

Gateway - A device that interconnects networks with different, incompatible communications protocols.

Half Duplex - Data transmission that can occur in two directions over a single line, but only one direction at a time.

HTTP (HyperTextTransportProtocol) - The communications protocol used to connect to servers on the World Wide Web.

Infrastructure - A wireless network that is bridged to a wired network via an access point.

IP (InternetProtocol) - A protocol used to send data over a network

IP Address - The address used to identify a computer or device on a network.

IPCONFIG - A Windows 2000 and XP utility that displays the IP address for a particular networking device.

IPSec (InternetProtocolSecurity) - A VPN protocol used to implement secure exchange of packets at the IP layer.

ISP (InternetServiceProvider) - A company that provides access to the Internet.

LAN - The computers and networking products that make up your local network.

MAC (MediaAccessControl)Address - The unique address that a manufacturer assigns to each networking device.

Mbps (MegaBitsPerSecond) - One million bits per second; a unit of measurement for data transmission.

NAT (NetworkAddressTranslation) - NAT technology translates IP addresses of a local area network to a different IP address for the Internet.

Packet - A unit of data sent over a network.

Passphrase - Used much like a password, a passphrase simplifies the WEP encryption process by automatically generating the WEP encryption keys for Linksys products.

Ping (PacketInternetGroper) - An Internet utility used to determine whether a particular IP address is online.

POP3 (PostOfficeProtocol3) - A standard mail server commonly used on the Internet.

Port - The connection point on a computer or networking device used for plugging in cables or adapters.

PoweroverEthernet (PoE) - A technology enabling an Ethernet network cable to deliver both data and power.

PPPoE (Point toPointProtocoloverEthernet) - A type of broadband connection that provides authentication (username and password) in addition to data transport.

PPTP (Point-to-PointTunnelingProtocol) - A VPN protocol that allows the Point to Point Protocol (PPP) to be tunneled through an IP network. This protocol is also used as a type of broadband connection in Europe.

38

RADIUS (RemoteAuthenticationDial-InUserService) - A protocol that uses an authentication server to control network access.

RJ-45 (RegisteredJack-45)- An Ethernet connector that holds up to eight wires.

Roaming - The ability to take a wireless device from one access point's range to another without losing the connection.

Router - A networking device that connects multiple networks together.

Server - Any computer whose function in a network is to provide user access to files, printing, communications, and other services.

SMTP (SimpleMailTransferProtocol) - The standarde-mailprotocol on the Internet.

SNMP (SimpleNetworkManagementProtocol) - A widely used network monitoring and control protocol.

SPI (StatefulPacketInspection)Firewall - A technology that inspects incoming packets of information before allowing them to enter the network.

SSID (ServiceSetIDentifier) - Wireless network's name.

Static IP Address - A fixed assigned address to a computer or device that is connected to a network.

Static Routing - Forwarding data in a network via a fixed path.

Subnet Mask - An address code that determines the size of the network.

Switch - 1. A data switch that connects computing devices to host computers, allowing a large number of devices to share a limited number of ports. 2. A device for making, breaking, or changing the connections in an electrical circuit.

TCP (TransmissionControlProtocol) - A network protocol for transmitting data that requires acknowledgement from the recipient of data sent.

TCP/IP (TransmissionControlProtocol/InternetProtocol) - A set of instructions PCs use to communicate over a network.

Telnet - A user command and TCP/IP protocol used for accessing remote PCs.
