Wireless Router TwinMOS Page 28verify that you are in accordance with your service agreement before sharing Internet access.
Wireless Router TwinMOS Page 29Glossary 10BaseT or 100BaseTx: 802.3 based Ethernet network that uses UTP (Unshielded twisted pair) cable and a star topology. 10 is 10 Mbps and 100 is 100 Mbps. 802.1x: The standard for wireless LAN authentication used between an AP and a client. 802.1x with EAP will initiate key handling. Ad-Hoc Network: The wireless network based on a peer-to-peer communications session. Also referred to as AdHoc. Access Point : Access points are way stations in a wireless LAN that are connected to an Ethernet hub or server. Users can roam within the range of access points and their wireless device connections are passed from one access point to the next. Authentication: Authentication refers to the verification of a transmitted message's integrity. DMZ: DMZ (DeMilitarized Zone) is a part of an network that is located between a secure LAN and an insecure WAN. DMZs provide a way for some clients to have unrestricted access to the Internet. DHCP: DHCP (Dynamic Host Configuration Protocol) software automatically assigns IP addresses to client stations logging onto a TCP/IP network, which eliminates the need to manu-ally assign permanent IP addresses. DSSS (Direct Sequence Spread Spectrum): Method of spreading a wireless signal into wide frequency bandwidth. DTE (Data Terminal Equipment): Device that controls data flowing to and from a computer. Dynamic IP Address: An IP address that is automatically assigned to a client station in a TCP/IP network, typically by a DHCP server. DNS (Domain Name System): System used to map readable machine names into IP addresses DTIM:DTIM (Delivery Traffic Indication Message) provides client stations with information on the next opportunity to monitor for broadcast or multicast messages. Filter: Filters are schemes which only allow specified data to be transmitted. For example, the router can filter specific IP addresses so that users cannot connect to those addresses. Firewall: Firewalls are methods used to keep networks secure from malicious intruders and unauthorized access. Firewalls use filters to prevent unwanted packets from being transmitted. Firewalls are typically used to provide secure access to the Internet while keeping an organization’s public Web
Wireless Router TwinMOS Page 30server separate from the internal LAN. Firmware: Programming inserted into programmable read-only memory, thus becoming a permanent part of a computing device. Fragmentation: Refers to the breaking up of data packets during transmis-sion. Gateway: Gateways are computers that convert protocols enabling different networks, applications, and operating systems to exchange information. Half-duplex: To transmit on the same channel in both directions, one direction at a time. Host Name: The name given to a computer or client station that acts as a source for information on the network. ISP: An ISP is an organization providing Internet access service via modems, ISDN (Integrated Services Digital Network), and private lines. LAN(Local Area Network): A group of computers and peripheral devices connected to share resources. MAC(Medium Access Control) Address: A unique number that distinguishes network cards. MTU: MTU (Maximum Transmission/Transfer Unit) is the largest packet size that can be sent over a network. Messages lar-ger than the MTU are divided into smaller packets. NAT: NAT (Network Address Translation - also known as IP mas-querading) enables an organization to present itself to the Internet with one address. NAT converts the address of each LAN node into one IP address for the Internet (and vice versa). NAT also provides a certain amount of security by acting as a firewall by keeping individual IP addresses hidden from the WAN. PPPoE: PPPoE (Point-to-Point Protocol Over Ethernet) is used for running PPP protocol (normally used for dial-up Internet connections) over an Ethernet. PoE (Power over Ethernet): A mechanism to send DC power to a device using a CAT5 Ethernet cable. Preamble: Preamble refers to the length of a CRC (Cyclic Redundancy Check) block that monitors communications between roam-ing wireless enabled devices and access points.
Wireless Router TwinMOS Page 31Protocol: A standard way of exchanging information between computers. RADIUS (Remote Authentication Dial In User Service): A server that issues authentication key to clients. RAM (Random Access Memory): Non-permanent memory. RIP: RIP (Routing Information Protocol) is a routing protocol that is integrated in the TCP/IP protocol. RIP finds a route that is based on the smallest number of hops between the source of a packet and its destination. Router: Device that can connect individual LANs and remote sites to a server. Roaming: The ability to use a wireless device while moving from one access point to another without losing the connection. RTS: RTS (Request To Send) is a signal sent from the transmitting station to the receiving station requesting permission to trans-mit data. Server: Servers are typically powerful and fast machines that store programs and data. The programs and data are shared by client machines (workstations) on the network. SMTP: SMTP (Simple Mail Transfer Protocol) is the standard Inter-net e-mail protocol. SMTP is a TCP/IP protocol defining message format and includes a message transfer agent that stores and forwards mail. SNMP: SNMP (Simple Network Management Protocol) is a widely used network monitoring and control protocol. SNMP hard-ware or software components transmit network device activity data to the workstation used to oversee the network. Static IP Address: A permanent IP address is assigned to a node in a TCP/IP network. Also known as global IP. STP (Shielded Twisted Pair): Twisted Pair cable wrapped in a metal sheath to provide extra protection from external interfering signals. Subnet Mask: Subnet Masks (SUBNETwork masks) are used by IP proto-col to direct messages into a specified network segment (i.e., subnet). A subnet mask is stored in the client machine, server or router and is compared with an incoming IP ad-dress to determine whether to accept or reject the packet. SSID: SSID (Service Set Identifier) is a security measure used in WLANs. The SSID is a unique identifier attached to packets sent over WLANs. This identifier emulates a password when a wireless device attempts communication on the WLAN. Because an SSID distinguishes WLANS from each other, access points and wireless devices trying to connect to a WLAN must use the same SSID. TCP/IP: TCP/IP (Transmission Control Protocol/Internet Protocol) is the main Internet communications protocol. The TCP part ensures that data is completely sent and received at the other end. Another part of the TCP/IP protocol set is UDP, which is used to send data when accuracy and guaranteed packet delivery are not as important (for example, in real-time video and audio transmission).
Wireless Router TwinMOS Page 32 TFTP (Trivial File Transfer Protocol): Simple form of FTP (File Transfer Protocol), which Uses UDP (User Datagram Protocol), rather than TCP/IP for data transport and provides no security features. TKIP (Temporal Key Integrity Protocol): An encryption method replacing WEP.TKIP uses random IV and frequent key exchanges. UDP (User Datagram Protocol): A communication method (protocol) that offers a limited amount of service when messages are exchanged between computers in a network. UDP is used as an alternative to TCP/IP. Uplink: Link to the next level up in a communication hierarchy. UTP (Unshielded Twisted Pair) cable: Two or more unshielded wires twisted together to form a cable. Virtual Servers: Virtual servers are client servers (such as Web servers) that share resources with other virtual servers (i.e., it is not a dedicated server). WEP (Wired Equivalent Privacy): An encryption method based on 64 or 128bit algorithm. Web Browser: A software program that allows viewing of web pages. WAN: WAN (Wide Area Network) is a communications network that covers a wide geographic area such as a country (con-trasted with a LAN, which covers a small area such as a company building). WLAN: WLANs (Wireless LANs) are local area networks that use wireless communications for transmitting data. Transmis-sions are usually in the 2.4 GHz band. WLAN devices do not need to be lined up for communications like infrared devices. WLAN devices use access points which are con-nected to the wired LAN and provide connectivity to the LAN. The radio frequency of WLAN devices is strong enough to be transmitted through non-metal walls and ob-jects, and can cover an area up to a thousand feet. Laptops and notebooks use wireless LAN PCMCIA cards while PCs use plug-in cards to access the WLAN. VPN (Virtual Private Network): A security method to connect remote LAN users to a corporate LAN system.
