User Manual 33 3.7 Glossary ADSL Asymmetric Digital Subscriber Line ADSL is a technology for transmitting digital information at a high bandwidth on existing phone lines to homes and businesses. Unlike regular dial-up phone service, ADSL provides continuously-available, "always on" connection. ADSL is asymmetric in that it uses most of the channel to transmit downstream to the user and only a small part to receive information from the user. ADSL simultaneously accommodates analog (voice) information on the same line. ADSL is generally offered at downstream data rates from 512 kbit/s to about 6 Mbit/s. ADSL2+ Asymmetric Digital Subscriber Line 2+ ADSL2plus doubles the bandwidth used for downstream data transmission, effectively doubling the maximum downstream data rates, and achieving rates of 20 Mbit/s on phone lines as long at 5,000 feet. ADSL2plus solutions will most commonly be multimode, interoperating with ADSL and ADSL2, as well as with ADSL2plus chipsets. Browser A computer program that allows users to view information from the Internet. To use a browser, you type in the URL of a website, and the browser then connects your computer to the website, and shows the information there on your screen. Client On a local area network or the Internet, a computer that accesses shared network resources provided by another computer (called a server). DHCP Dynamic Host Configuration Protocol DHCP is a client-server networking protocol. Most organizations use DHCP. A DHCP server provides configuration parameters specific to the DHCP client host requesting, generally, information required by the host to participate on the Internet network. DHCP also provides a mechanism for allocation of IP addresses to hosts. DNS Domain Name System A hierarchical way of tracking domain names and their addresses, devised in the mid-1980s. The DNS database does not rely on one file or even one server, but rather is distributed over several key computers across the Internet to prevent catastrophic failure if one or a few computers go down. DNS is a TCP/IP service that belongs to the Application layer of the OSI model. Ethernet A local area network (LAN) architecture developed by Xerox Corporation in cooperation with DEC and Intel in 1976. Ethernet uses a bus or star topology and supports data User Manual 34 transfer rates of 10 Mbit/s. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Ethernet uses the CSMA/CD access method to handle simultaneous demands. It is one of the most widely implemented LAN standards. IEEE Institute of Electrical and Electronics Engineers (IEEE) is a standards organization for computer and electronic devices. Its senior members are IEEE fellows. Internet Largest global internet work, connecting tens of thousands of networks worldwide and having a "culture" that focuses on research and standardization based on real-life use. Many leading-edge network technologies come from the Internet community. The most important using for Internet is: z z z z z z z The email The World Wide Web (WWW) The transfer of data The forum of discussion To transfer data of peer-to-peer Chat The content of audio/video streaming IP Internet Protocol The set of standards responsible for ensuring that data packets transmitted over the Internet are routed to their intended destinations. IP address An IP address is the logical address of a network adapter. The IP address uniquely identifies computers on a network. An IP address can be private, for use on a LAN, or public, for use on the Internet or other WAN. kbit/s Kilobit per second A unit used to express the speed of a network. LAN Local Area Network A computer network covering a small local area, like a home, office, or small group of buildings such as a home, office, or college. Current LANs are most likely to be based on switched Ethernet or Wi-Fi technology running at 10, 100 or 1,000 Mbit/s (1,000 Mbit/s is also known as 1 Gbit/s). MAC address It is a hardware address that uniquely identifies each node of a network. User Manual 35 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. User Manual 36 URL Universal Resource Locator 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.
