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 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 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

bridg­ingg­

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
