Appendix C: 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 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 type of DSL for home users. The term asym-
metrical refers to its unequal data rates for download-
ing and uploading (the download rate is higher than the
upload rate). The asymmetri cal rates benefit home users
because they typically download much more data from
the Internet than they upload.
analog Of data, having a form is analogous to the data’s origi-
nal waveform. The voice component in DSL is an analog
signal. See also 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 also 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 11010001.10111111.000001
00.11110000 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.
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 My ADSL Modem 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 also 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.
