NAT stands for Network Address Translation. Since a NAT gateway exposes only a single IP address to
the outside Internet, it’s useful for security.
Port mapping
The act of mapping a port on an Internet-accessible NAT gateway to another port on a machine on your
internal network. Port mapping enables you to run a public Internet service on a machine that is otherwise
hidden from the Internet by your NAT gateway. Other names for port mapping include “port forwarding,”
“pass-through,” and “punch-through.”
Router
An intelligent network device that goes one step beyond bridging by converting address-based protocols
that describe how packets move from one place to another. In practice, this generally comes down to
translating between IP addresses and MAC addresses for data flowing between your local network and
the Internet. Many people use the term interchangeably with “gateway.” You must enter the IP address of
your router when configuring network settings manually.
SSID
Service Set Identifier, a set of characters that give a unique name to a WLAN.
Subnet mask
A network setting that indicates the size of the network you’re on.
Switch
A specific type of hub that isolates the communications between any two computers from the rest of the
network, thus increasing throughput. Switches are also called “switching hubs.”
TKIP
An encryption key that’s part of WPA. TKIP stands for Temporal Key Integrity Protocol. It’s nominally
weaker than the government-grade AES, but in the real world, TKIP is more than strong enough.
WAN
Wide Area Network, A collection of local area networks connected by a variety of physical means. The
Internet is the largest and most well-known wide area network. Wide area network is generally
abbreviated to WAN.
WAP
Wireless Application Protocol, a set of standards to enable wireless devices to access Internet services,
such as the World Wide Web and email.
WEP
An encryption system for preventing eavesdropping on wireless network traffic. WEP stands for Wired
Equivalent Privacy. WEP is easily broken, and is in the process of being replaced by WPA.
WLAN
Wireless Local Access Network, a LAN that can be connected to via a wireless connection.
WPA
A modern encryption system for preventing eavesdropping on wireless network traffic that solves the
problems that plagued WEP. WPA stands for Wi-Fi Protected Access.
Voice-over-IP
A way of making telephone calls over a packet-switched network like the Internet. Voice-over-IP requires
special telephones and software. Voice-over-IP is commonly abbreviated to VoIP.
