Gateway
A network node that acts as an entrance to another network, for example between a
company network and the Internet.
Infrastructure
Devices in an infrastructure network communicate via one or more wireless access
points. The WT-1 supports an infrastructure mode for connection to a wireless network
via an access point.
IP address
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.
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.
PASV mode
PASV mode is used by clients behind fi rewalls, 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
defi ning 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 fi rewall.
