72 GLOSSARYaccess point. It offers lower performance than infra-structure mode, usedby the Access Point. (see also Infra-structure mode.)Auto-negotiation Some devices in the OfficeConnect range support auto-negotiation.Auto-negotiation is where two devices sharing a link, automaticallyconfigure to use the best common speed. The order of preference (bestfirst) is: 100BASE-TX full duplex, 100BASE-TX half duplex, 10BASE-T fullduplex, and 10BASE-T half duplex. Auto-negotiation is defined in the IEEE802.3 standard for Ethernet and is an operation that takes place in a fewmilliseconds.Bandwidth The information capacity, measured in bits per second, that a channel cantransmit. The bandwidth of Ethernet is 10 Mbps, the bandwidth of FastEthernet is 100 Mbps. The bandwidth for 802.11b wireless is 11Mbps.The bandwidth for 802.11g is 54 Mbps.Category 3 Cables One of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586standard. Category 3 is voice grade cable and can only be used inEthernet networks (10BASE-T) to transmit data at speeds of up to 10Mbps.Category 5 Cables One of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586standard. Category 5 can be used in Ethernet (10BASE-T) and FastEthernet networks (100BASE-TX) and can transmit data up to speeds of100 Mbps. Category 5 cabling is better to use for network cabling thanCategory 3, because it supports both Ethernet (10 Mbps) and FastEthernet (100 Mbps) speeds.Channel Similar to any radio device, the OfficeConnect Wireless 11g Access Pointallows you to choose different radio channels in the wireless spectrum. Achannel is a particular frequency within the 2.4GHz spectrum withinwhich the Gateway operates.Client The term used to described the desktop PC that is connected to yournetwork.DHCP Dynamic Host Configuration Protocol. This protocol automatically assignsan IP address for every computer on your network. Windows 95,Windows 98 and Windows NT 4.0 contain software that assigns IPaddresses to workstations on a network.
