authenticate To verify a user’s identity, such as by prompting for a pass-
word.
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 ex
-
pressed 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
bit, IP address, network mask .
bit Short for “binary digit,” a bit is a number that can have two
values, 0 or 1. See
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 intel-
ligence to data transfers by using network addresses instead.
The Wireless ADSL2+ Router can perform both routing and
bridging. Typically, when both functions are enabled, the de -
vice routes IP data and bridges all other types of data. See
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 from a shared pool of IP addresses; after a speci-
fied time limit, DHCP returns the address to the pool.
DHCP relay Dynamic Host Configuration Protocol relay
A DHCP relay is a computer that forwards DHCP data be-
tween computers that request IP addresses and the DHCP
server that assigns the addresses. Each of the Wireless
ADSL2+ Router’s interfaces can be configured as a DHCP
relay. See
DHCP .
