Appendix F: Glossary of Network and VoIP Terms

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 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	Of data, having a form is analogous to the data’s original
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 11010001.10111111.00000100.1
	1110000 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 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.
