Appendix A: Glossary
Access Point
An access point is a wired controller that sends data to the wireless NICs installed in your
network computers, and received data back from them. An AP is often connected to the
Network computer that has Internet access, or is directly connected to a ADSL or cable
modem.
ADSL
Asymmetric digital subscriber line (ADSL) is a new modem technology that converts existing twisted-pair telephone lines into access paths for high-speed communications of various sorts.
Auto-MDI/MDIX
On a network hub or switch, an auto-MDI/MDIX port automatically senses if it needs to act
as a MDI or MDIX port. The auto-MDI/MDIX capability eliminates the need for crossover
cables.
Auto-negotiate
To automatically determine the correct settings. The term is often used with communications and networking.
DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating
the configuration of computers that use TCP/IP. DHCP can be used to automatically assign IP addresses, to deliver TCP/IP stack configuration parameters such as the subnet
mask and default router, and to provide other configuration information such as the addresses for printer, time and news servers.
DSSS
Also known as “Direct Sequence Spread Spectrum,” this is a variety of radio transmission
methods that continuously change frequencies or signal patterns. Direct Sequence Spread
Spectrum (DSSS), which is used in CDMA, multiplies the data bits by a very fast, pseudorandom bit pattern (PN sequence) that “spreads” the data into a large coded stream that
takes the full bandwidth of the channel.
56
GN-A15AG Wireless Access Point User Guide
DNS
The Domain Name System (DNS) is a distributed Internet directory service. DNS is used
mostly to translate between domain names and IP addresses, and to control Internet email
delivery. Most Internet services rely on DNS to work, and if DNS fails, web sites cannot be
located and email delivery stalls.
Dynamic IP Address
An IP address that is automatically assigned to a client station in a TCP/IP network,
typically by a DHCP server.
Firewall
A system designed to prevent unauthorized access to or from a private network. Firewalls
can be implemented in both hardware and software, or a combination of both. Firewalls
are frequently used to prevent unauthorized Internet users from accessing private
networks connected to the Internet, especially intranets. All messages entering or leaving
the intranet pass through the firewall, which examines each message and blocks those
that do not meet the specified security criteria.
Gateway
A device, usually a router, that connects hosts on a local network to other networks.
IP Address
Every machine on the Internet has a unique identifying number, called an IP Address. A
typical IP address looks like this: 216.27.61.137
MAC Address
On a local area network (LAN) or other network, the MAC (Media Access Control) address
is your computer's unique hardware number. Usually written in the form 01:23:45:67:89:
ab
Ping (Packet Internet Groper)
A utility to determine whether a specific IP address is accessible. It works by sending a
packet to the specified address and waiting for a reply. PING is used primarily to troubleshoot Internet connections.
Router
A device that forwards data packets along networks. A router is connected to at least two
networks, commonly two LANs or WANs or a LAN and its ISP’s network. Routers are
located at gateways, the places where two or more networks connect.
57
GN-A15AG Wireless Access Point User Guide
SSID
The SSID is the name represent the router in the wireless network.
Subnet Mask
A mask used to determine what subnet an IP address belongs to. An IP address has two
components, the network address and the host address. Subnetting enables the network
administrator to further divide the host part of the address into two or more subnets.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol), the suite of communications
protocols used to connect hosts on the Internet.
WAN
Wide Area Network, a communication network that covers a relatively large geographic
area, consisting of two or more LANs. Broadband communication over the WAN is often
through public networks such as the ADSL or Cable systems, or through leased lines or
satellites. In its most basic definition, the Internet could be considered a WAN.
WEP
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a 64/128-bit shared
key algorithm, as described in the IEEE 802.11 standard.
