IEEE 802.11a/b/g: Wireless LAN standards proposed by the 802 committee, which develops LAN technology standards for the IEEE.

IIS (Internet Information Services): Microsoft’s name for its Web server software. Notable for its close connection to Windows-based systems through Active Server Pages (ASPs). When installed as part of the operating system, IIS makes it relatively easy to build web a server.

Infrastructure: Devices in an infrastructure network communicate via wireless access points that may be connected to an Ethernet network, allowing wireless and Ethernet devices to coexist on a single network.

IP address: The address given to each node in a TCP/IP network. All nodes in a TCP/IP network must have a unique IP address. Private IP addresses are recommended for nodes that are part of a local network.

Key index: A number identifying which WEP key is to be used for encryption when communicating via an access point with more than one WEP key. All devices on the network must use the same key index.

LAN (Local Area Network): A network of computers located in relatively close proximity to one another. LANs generally support data transfer speeds of 10–100 Mbps.

MAC (Media Access Control) Address: A unique hardware address for each device on a network, required when sending and receiving packets.

Open system: The name given to a wireless network using no authentication (open authentication). Open systems are relatively insecure, as a password is not required to gain access to the server.

PASV mode: PASV mode is used by clients behind firewalls, when it allows the ftp server to supply the port number.

Private IP address: An IP address that is only visible within a local network. Because packets using a private IP address can not be transmitted to another network, they are usually sent between networks via a proxy server or NAT. Private IP addresses in the range 10.0.0.0–10.255.255.255 are termed “class A.” Class B addresses are in the range 172.16.0.0– 172.31.255.255, class C addresses in the range 192.168.0.0– 192.168.255.255. The class of address used depends on the size of the network. Class C addresses are often used for small networks.

Protocol: A set of rules for passing information back and forth between devices in a network. By defining such elements of communication as how links are established, how receipt of a signal is acknowledged, how data are encoded, and how to handle errors, a protocol ensures that data are transmitted without loss of information.

Proxy: A server that stands between large networks and local networks or computers, typically to ensure security. One element of a firewall.
