Glossary
Channel number
Frequency used for wireless communications.
Wireless communications are available only among client computers and Access Points that use the same channel.
Client
Computer on a wireless LAN. It may be called a client computer as well.
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 rather hard to remember, 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.
Encryption Key
Key used in the IEEE802.11-compliant security system (WEP).
Using the Encryption Key as the password, only client computers and Access Points that have the same ID and password
may log onto the same wireless LAN for file sharing.
LAN (Local Area Network)
A network which is accessible only to its members, unlike the Internet which is open to an unlimited number of people.
A LAN may be built for different purposes. For example, you can build an office LAN that is accessible only to members of the
same department or a home LAN that is accessible only to family members.
SSID (Service Set ID)
IEEE802.11-compliant wireless LAN group identifier.
The Access Point uses the Access Point ID for the SSID.
WAN (Wide Area Network)
A network that interconnects remote LANs through the Internet or telephone lines.
