Mbit/s

Megabit per second

A unit used to express the speed of a network.

NAPT

Network Address Port Translation

NAPT enables a local area network (LAN) to use one set of IP addresses for internal traffic

and a second set of addresses for external traffic.

PPPoE

Point-to-Point Protocol over Ethernet

PPPoE is a network protocol for encapsulating PPP frames in Ethernet frames. It is used

mainly with DSL services. It offers standard PPP features such as authentication,

encryption, and compression.

Protocol

On the Internet, "protocol" usually refers to a set of rules that define an exact format for

communication between systems.

Server

A computer or program that responds to commands from a client. For example, a file

server may contain an archive of data or program files. When a client submits a request

for a file, the server transfers a copy of the file to the client.

Subnet mask

The technique used by the IP protocol to determine which network segment packets are

destined for. The subnet mask is a binary pattern that is stored in the client machine,

server or router, and is matched with the IP address.

TCP

Transmission Control Protocol

The reliable transport protocol within the TCP/IP protocol suite. TCP ensures that all data

arrive accurately and 100% intact at the other end. TCP's unreliable counterpart is UDP,

which is used for streaming media, VoIP and videoconferencing.

TCP/IP

A suite of communications protocols used to connect hosts on the Internet. TCP/IP uses

several protocols, the two main ones being TCP and IP.

UDP

User Datagram Protocol

One of the TCP/IP suite of protocols for data transfer, which allows an application program

on one machine to send a datagram to an application program on another machine.

URL

Universal Resource Locator

User Manual

42

The global address of documents and other resources on the World Wide Web.

USB

Universal Serial Bus

USB is a serial protocol and physical link, which transmits all data differentially on a single

pair of wires. Another pair provides power to downstream peripherals.

Virtual server

A virtual server allows you to direct incoming traffic from the Internet (identified by

protocol and external port) to an internal server with a private IP address on the LAN.

WAN

Wide Area Network

WAN usually refers to a network which covers a large geographical area, and uses

communications circuits to connect the intermediate nodes. A major factor impacting

WAN design and performance is a requirement that they lease communications circuits

from telephone companies or other communications carriers.

Wi-Fi

Wireless Fidelity

A wireless data networking protocol generally used to connect PCs to a network. Also

known as 802.11b and WLAN (Wireless LAN), it is the most common means of wireless

networking and operates at 2.4 GHz.

WPA-PSK

Wi-Fi Protected Access-Pre Shared Key

WPA is an industry standard based on a subset of an early draft of 802.11i. WPA replaces

WEP's keying mechanism with a more robust system, called Temporal Key Integrity

Protocol (although TKIP is still based on RC4 encryption). (See full description of TKIP).

WPA adds a strong message integrity check and allows for authentication using 802.1X.

WEP

Wired Equivalent Privacy

Part of the IEEE 802.11 standard (ratified in September 1999), and is a scheme used to

secure wireless networks (Wi-Fi). Because a wireless network broadcasts messages using

radio, it is particularly susceptible to eavesdropping; WEP was designed to provide

comparable confidentiality to a traditional wired network, hence the name.
