10BASE-T
IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3, 4, or 5
UTP cable.
100BASE-TX
IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5
or better UTP cable.
Auto-Negotiation
Signalling method allowing each node to select its optimum operational mode (e.g.,
speed and duplex mode) based on the capabilities of the node to which it is
connected.
Bandwidth
The difference between the highest and lowest frequencies available for network
signals. Also synonymous with wire speed, the actual speed of the data
transmission along the cable.
Bridging
A device that connects two LANs, or two segments of the same LAN. Unlike routers,
bridges are protocol-independent. They simply forward packets without analyzing
and re-routing messages. Consequently, they’re faster than routers, but less
versatile.
Challenge-Handshake Authentication Protocol (CHAP)
A type of authentication in which the authentication agent (that is, the router) sends
the client a key to use to encrypt the user name and password. This enables the
user name and password to be transmitted in an encrypted form to protect them
against eavesdroppers.
Domain Name Service (DNS)
A system used for translating host names for network nodes into IP addresses.
Dynamic Host Control Protocol (DHCP)
Provides a framework for passing configuration information to hosts on a TCP/IP
network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability
of automatic allocation of reusable network addresses and additional configuration
options.
