10BASE-T
A designation for the type of wiring used by Ethernet networks with a data rate of
10 Mbps. Also known as Category 3 (CAT 3) wiring. See also data rate, Ethernet.
100BASE-T
A designation for the type of wiring used by Ethernet networks with a data rate of
100 Mbps. Also known as Category 5 (CAT 5) wiring. See also data rate, Ethernet.
ADSL
Asymmetric Digital Subscriber Line
The most commonly deployed "flavor" of DSL for home users. The term
asymmetrical refers to its unequal data rates for downloading and uploading (the
download rate is higher than the upload rate). The asymmetrical rates benefit
home users because they typically download much more data from the Internet
than they upload.

analog
ATM authenticate
To verify a user’s identity, such as by prompting for a
password.
binary
The "base two" system of numbers, that uses only two digits, 0 and 1, to represent
all numbers. In binary, the number 1 is written as 1, 2 as 10, 3 as 11, 4 as 100, etc.
Although expressed as decimal numbers for convenience, IP addresses in actual
use are binary numbers; e.g., the IP address 209.191.4.240 is
11010001.10111111.00000100.11110000 in binary. See also bit, IP address,
network mask.

bit
Short for "binary digit," a bit is a number that can have two values, 0 or 1. See also
binary.

broadband
A telecommunications technology that can send different types of data over the
same medium. DSL is a broadband technology.
broadcast
To send data to all computers on a network.
DHCP
Dynamic Host Configuration Protocol
DHCP automates address assignment and management. When a computer
connects to the LAN, DHCP assigns it an IP address from a shared pool of IP
addresses; after a specified time limit, DHCP returns the address to the pool.

DHCP relay
Dynamic Host Configuration Protocol relay
A DHCP relay is a computer that forwards DHCP data between computers that
request IP addresses and the DHCP server that assigns the addresses. Each of
the SL-6000 / SL-6300's interfaces can be configured as a DHCP relay. See
DHCP.

Dynamic Host Configuration Protocol server
A DHCP server is a computer that is responsible for assigning IP addresses to the
computers on a LAN. See DHCP.

DNS
Domain Name System
The DNS maps domain names into IP addresses. DNS information is distributed
hierarchically throughout the Internet among computers called DNS servers. When
you start to access a web site, a DNS server looks up the requested domain name
to find its corresponding IP address. If the DNS server cannot find the IP address,
it communicates with higher-level DNS servers to determine the IP address. See
also domain name.

domain name
A domain name is a user-friendly name used in place of its associated IP address.
For example, www.globespan.net is the domain name associated with IP address
209.191.4.240. Domain names must be unique; their assignment is controlled by
the Internet Corporation for Assigned Names and Numbers (ICANN). Domain
names are a key element of URLs, which identify a specific file at a web site, e.g.,
http://www.globespan.net/index.html. See also DNS.
