bridging
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.
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.
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 uplo-
ading (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.
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.
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.
To verify a user's identity, such as by prompting for a password.
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 11010001.10111111.00000
100.11110000 in binary. See bit, IP address, network mask.
Short for "binary digit, " a bit is a number that can have two values, 0 or 1. See binary.
bits per second
Passing data from your network to your ISP and vice versa using the hardware ad-
dresses of the devices at each location. Bridging contrasts with routing, which can
add more intelligence to data transfers by using network addresses instead. The
Wireless Gateway 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.
