DSL
DSL stands for Digital Subscriber Line. A DSL modem uses
your existing phone lines to transmit data at high speeds.
Ethernet
A standard for computer networks. Ethernet networks are
connected by special cables and hubs, and move data around
at up to 10 million bits per second (Mbps).
ESS
ESS (ESS-ID, SSID) stands for "Extended Service Set". More
than one BSS is configured to become an Extended Service Set.
LAN mobile users can roam between different BSSs in an ESS
(ESS-ID, SSID).
Fast Ethernet NIC
Network interface card that is in compliance with the IEEE 802.3u
standard. This card functions at the media access control (MAC)
layer, using carrier sense multiple access with collision detection
(CSMA/CD).
Fixed IP
(see Static IP)
Full-Duplex
Transmitting and receiving data simultaneously. In pure digital
networks, this is achieved with two pairs of wires. In analog
networks, or digital networks using carriers, it is achieved by
dividing the bandwidth of the line into two frequencies, one
for sending, one for receiving.
Hub
Central connection device for shared media in a star topology.
It may add nothing to the transmission (passive hub) or may
contain electronics that regenerate signals to boost strength
as well as monitor activity (active/intelligent hub). Hubs may be
