Ad 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
access point. It offers lower performance than infrastructure mode, which
is the mode the router uses. (see Infrastructure mode.)
Some 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.
The 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.
One 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.
One 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.
Similar 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.
The term used to describe the desktop PC that is connected to your
network.
