10Base-T: An ethernet standard for local Area network (lAn). 10base-T uses
a twisted-pair cable with a maximum length of 100 meters.
AAL: ATM Adaptation layer defines the rules governing segmentation and reassembly
of data into cells. different AAl types are suited to different traffic classes.
ADSL: An Asymmetric digital Subscriber line is an asymmetrical data transmission
technology with a high traffic rate downstream and a low traffic rate upstream.
AdSl technology satisfies the bandwidth requirement of applications that demand
"asymmetric" traffic; e.g., Web surfing, file downloading and video-on-demand.
ATM: Asynchronous Transfer Mode is a layer 2 protocol supporting high-speed
asynchronous data with advanced traffic management and quality-of-service features.
bps: bits per second, a standard measurement of digital transmission speeds.
Bridge: A device that connects two or more physical networks and forwards
packets between them. bridges can usually be made to filter packets; that is,
to forward only certain traffic. Related devices are repeaters, which simply
forward electrical signals from one cable to another, and full-fledged routers
that make routing decisions based on several criteria.
CPE: Customer Premises equipment, such as an AdSl router or USb modem.
Default Gateway (Router): every non-router IP device needs to configure a
default gateway's IP address. When the device sends out an IP packet, if the
destination is not on the same network, the device has to send the packet to its
default gateway, which will then send it out toward the destination.
DHCP: A dynamic Host Configuration Protocol automatically gives every
computer on your home network an IP address.
DNS Server IP Address: The domain name System (dnS) allows Internet servers to
have a domain name (e.g., www.broadbandrouter.com) and one or more IP
addresses (e.g., 192.34.45.8). A dnS server keeps a database of Internet servers
and their respective domain names and IP addresses so that when a domain name
is requested (as in typing "broadbandrouter.com" into an Internet browser) the user is
sent to the proper IP address. The dnS server IP address used by the computers on
a home network is the location of the dnS server the ISP has assigned.
DSL: digital line Subscriber (dSl) technology provides high-speed access over twisted-
pair cable for connection to the Internet and lAn interfaces, and to broadband
services such as video-on-demand, distance learning and video conferencing.
Ethernet: A standard for computer networks, ethernet networks are connected by
special cables and hubs or switches, and move data around at up to 10/100 Mbps.
FTP: File Transfer Protocol is the Internet protocol (and program) used to transfer
files between hosts.
