152APPENDIX E: OBTAINING SUPPORT FOR YOUR3COM PRODUCTS
GLOSSARY 802.11bThe IEEE specification for wireless Ethernet which allows speeds of up to 11 Mbps. The standard provides for 1, 2, 5.5 and 11 Mbps data rates. The rates will switch automatically depending on range and environment. 802.11gThe IEEE specification for wireless Ethernet which allows speeds of up to 54 Mbps. The standard provides for 6, 12, 24, 36, 48 and 54 Mbps data rates. The rates will switch automatically depending on range and environment. 802.11nThe IEEE specification for wireless Ethernet which allows speeds of up to 248 Mbps. 802.11n is a proposed amendment which improves upon the previous 802.11 standards by adding multiple-input multiple-output (MIMO) and many other newer features. 10BASE-TThe IEEE specification for 10 Mbps Ethernet over Category 3, 4 or 5 twisted pair cable. 100BASE-TXThe IEEE specification for 100 Mbps Fast Ethernet over Category 5 twisted-pair cable. Access PointAn access point is a device through which wireless clients connect to other wireless clients and which acts as a bridge between wireless clients and a wired network, such as Ethernet. Wireless clients can be moved anywhere within the coverage area of the access point and still connect with each other. If connected to an Ethernet network, the access point monitors Ethernet traffic and forwards appropriate Ethernet messages to the wireless network, while also monitoring wireless client radio traffic and forwarding wireless client messages to the Ethernet LAN. Ad Hoc modeAd Hoc mode is a configuration supported by most wireless clients. It is used to connect a peer to peer network together without the use of an
154GLOSSARY access point. It offers lower performance than infrastructure mode, which is the mode the router uses. (see also Infrastructure mode.)
GLOSSARY155 Auto-negotiationSome devices in the range support auto-negotiation. Auto-negotiation is where two devices sharing a link, automatically configure to use the best common speed. The order of preference (best first) is: 100BASE-TX full duplex, 100BASE-TX half duplex, 10BASE-T full duplex, and 10BASE-T half duplex. Auto-negotiation is defined in the IEEE 802.3 standard for Ethernet and is an operation that takes place in a few milliseconds. BandwidthThe information capacity, measured in bits per second, that a channel can transmit. The bandwidth of Ethernet is 10 Mbps, the bandwidth of Fast Ethernet is 100 Mbps. The bandwidth for 802.11b wireless is 11Mbps. Category 3 CablesOne of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586 standard. Category 3 is voice grade cable and can only be used in Ethernet networks (10BASE-T) to transmit data at speeds of up to 10 Mbps. Category 5 CablesOne of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586 standard. Category 5 can be used in Ethernet (10BASE-T) and Fast Ethernet networks (100BASE-TX) and can transmit data up to speeds of 100 Mbps. Category 5 cabling is better to use for network cabling than Category 3, because it supports both Ethernet (10 Mbps) and Fast Ethernet (100 Mbps) speeds. ChannelSimilar to any radio device, the Wireless Cable/DSL router allows you to choose different radio channels in the wireless spectrum. A channel is a particular frequency within the 2.4GHz spectrum within which the Router operates. ClientThe term used to describe the desktop PC that is connected to your network. DHCPDynamic Host Configuration Protocol. This protocol automatically assigns an IP address for every computer on your network. Windows 95, Windows 98 and Windows NT 4.0 contain software that assigns IP addresses to workstations on a network. These assignments are made by the DHCP server software that runs on Windows NT Server, and Windows 95 and Windows 98 will call the server to obtain the address. Windows 98 will allocate itself an address if no DHCP server can be found.
156GLOSSARY DNS Server AddressDNS stands for Domain Name System, which allows Internet host computers to have a domain name (such as 3com.com) and one or more IP addresses (such as 192.34.45.8). A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a domain name is requested (as in typing “3com.com” into your Internet browser), the user is sent to the proper IP address. The DNS server address used by the computers on your home network is the location of the DNS server your ISP has assigned. DSL modemDSL stands for digital subscriber line. A DSL modem uses your existing phone lines to send and receive data at high speeds. EncryptionA method for providing a level of security to wireless data transmissions. The Router uses two levels of encryption; 40/64 bit and 128 bit. 128 bit is a more powerful level of encryption than 40/64 bit. ESSIDExtended Service Set Identifier. The ESSID is a unique identifier for your wireless network. You must have the same ESSID entered into the Router and each of its wireless clients. EthernetA LAN specification developed jointly by Xerox, Intel and Digital Equipment Corporation. Ethernet networks use CSMA/CD to transmit packets at a rate of 10 Mbps over a variety of cables. Ethernet AddressSee MAC address. Fast EthernetAn Ethernet system that is designed to operate at 100 Mbps. FirewallElectronic protection that prevents anyone outside of your network from seeing your files or damaging your computers. Full DuplexA system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential throughput of a link. Half DuplexA system that allows packets to transmitted and received, but not at the same time. Contrast with full duplex.
GLOSSARY157 HubA device that regenerates LAN traffic so that the transmission distance of that signal can be extended. Hubs are similar to repeaters, in that they connect LANs of the same type; however they connect more LANs than a repeater and are generally more sophisticated. IEEEInstitute of Electrical and Electronics Engineers. This American organization was founded in 1963 and sets standards for computers and communications. IETFInternet Engineering Task Force. An organization responsible for providing engineering solutions for TCP/IP networks. In the network management area, this group is responsible for the development of the SNMP protocol. Infrastructure modeInfrastructure mode is the wireless configuration supported by the Router. You will need to ensure all of your clients are set up to use infrastructure mode in order for them to communicate with the Access Point built into your Router. (see also Ad Hoc mode) IPInternet Protocol. IP is a Layer 3 network protocol that is the standard for sending data through a network. IP is part of the TCP/IP set of protocols that describe the routing of packets to addressed devices. An IP address consists of 32 bits divided into two or three fields: a network number and a host number or a network number, a subnet number, and a host number. IP AddressInternet Protocol Address. A unique identifier for a device attached to a network using TCP/IP. The address is written as four octets separated with periods (full-stops), and is made up of a network section, an optional subnet section and a host section. IPsecIP Security. Provides IP network-layer encryption. IPSec can support large encryption networks (such as the Internet) by using digital certificates for device authentication. When setting up an IPSec connection between two devices, make sure that they support the same encryption method. ISPInternet Service Provider. An ISP is a business that provides connectivity to the Internet for individuals and other businesses or organizations.
158GLOSSARY LANLocal Area Network. A network of end stations (such as PCs, printers, servers) and network devices (hubs and switches) that cover a relatively small geographic area (usually not larger than a floor or building). LANs are characterized by high transmission speeds over short distances (up to 1000 metres). MACMedia Access Control. A protocol specified by the IEEE for determining which devices have access to a network at any one time. MAC AddressMedia Access Control Address. Also called the hardware or physical address. A Layer 2 address associated with a particular network device. Most devices that connect to a LAN have a MAC address assigned to them as they are used to identify other devices in a network. MAC addresses are 6 bytes long. NATNetwork Address Translation. NAT enables all the computers on your network to share one IP address. The NAT capability of the Router allows you to access the Internet from any computer on your home network without having to purchase more IP addresses from your ISP. NetworkA network is a collection of computers and other computer equipment that is connected for the purpose of exchanging information or sharing resources. Networks vary in size, some are within a single room, others span continents. Network Interface Card (NIC)A circuit board installed into a piece of computing equipment, for example, a computer, that enables you to connect it to the network. A NIC is also known as an adapter or adapter card. ProtocolA set of rules for communication between devices on a network. The rules dictate format, timing, sequencing and error control. PPPoEPoint-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method of data transmission originally created for dial-up connections; PPPoE is for Ethernet connections. PPTPPoint-to-Point Tunneling Protocol is a method of secure data transmission between two remote sites over the Internet.
