Glossary
Channel number
The frequency used for wireless
communications. Wireless
communications are available only among
client computers and Access Points that
use the same channel.
Client
A computer connected to a LAN (Local
Area Network). Also may be called a
client computer.
DHCP (Dynamic Host
Configuration Protocol)
DHCP lets network administrators
centrally manage and automate
assignment of client computer IP
addresses.
DNS (Domain Name System)
A system that translates host names into
IP addresses.
Networks that use the TCP/IP protocol,
such as the Internet, use a set of numbers
like 192.168.0.1 (IP address) to identify a
computer. However, since the IP address
is hard to memorize, DNS was developed
to allow a name like “www.sony.com” to
identify a computer for convenience. DNS
servers manage these translations from
host names into IP addresses.
