Glossary
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 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 data rate, Ethernet .
ADSL Asymmetric Digital Subscriber Line
The most commonly deployed “flavor” of DSL for home users is asymmetrical DSL. 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 An analog signal is a signal that has had its frequency modified in some way,
such as by amplifying its strength or varying its frequency, in order to add information to the
signal. The voice component in DSL is an analog signal. See digital .
ATM Asynchronous Transfer Mode
A standard for high-speed transmission of data, text, voice, and video, widely used within the
Internet. ATM data rates range from 45 Mbps to 2.5 Gbps. See data rate .
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 bit,
IP address, network mask
.
bit
Short for “binary digit,” a bit is a number that can have two values, 0 or 1. See binary .
bps
bits per second
bridging Passing data from your network to your ISP and vice versa using the hardware
addresses of the devices at each location. Bridging contrasts with routing, which can add more
intelligence to data transfers by using network addresses instead. The Integrated Access Device
can perform both routing and bridging. Typically, when both functions are enabled, the device
routes IP data and bridges all other types of data. See routing .
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 Integrated Access
Device ‘s interfaces can be configured as a DHCP relay. See DHCP .
DHCP server 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 .
digital Of data, having a form based on discrete values expressed as binary numbers (0’s and
1’s). The data component in DSL is a digital signal. See analog .
