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 "flavor" 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 
11010001.10111111.00000100.11110000 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 VisionNet 
202ER-4 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. 
DHCP 
Dynamic Host Configuration Protocol 
DHCP automates address assignment and management. When 
a computer connects to the LAN, DHCP assigns it an IP address
