Appendix
Firewall - A firewall determines which information passes in and out of a
network. NAT can create a natural firewall by hiding a local network's IP
addresses from the Internet. A Firewall prevents anyone outside of your
network from accessing your computer and possibly damaging or viewing
your files.
Gateway - A network point that manages all the data traffic of your network,
as well as to the Internet and connects one network to another.
IEEE - The Institute of Electrical and Electronics Engineers. The IEEE
sets standards for networking, including Ethernet LANs. IEEE standards
ensure interoperability between systems of the same type.
IP Address (Internet Protocol) - An IP address consists of a series of four
numbers separated by periods, that identifies a unique Internet computer
host, allowing messages intended for that computer to be delivered to the
correct destination.
ISP (Internet Service Provider) - An ISP is a business that allows
individuals or businesses to connect to the Internet. Users log on to the
Internet using an account with an ISP or Internet Service Provider. ISPs
can serve IP addresses dynamically, or assign static (fixed) IP addresses to
individual computers.
ISP Gateway Address - The ISP Gateway Address is an IP address for the
Internet router. This address is only required when using a cable or DSL
modem.
LAN (Local Area Network) - A LAN is a group of computers and devices
connected together in a relatively small area (such as a house or an office).
Your home network is considered a LAN.
MAC Address (Media Access Control) - A MAC address is the hardware
address of a device connected to a network.
NAT (Network Address Translation) - NAT masks a local network's group
of IP addresses from the external network, allowing a local network of
computers to share a single ISP account. This process allows all of the
computers on your home network to use one IP address. This will enable
access to the Internet from any computer on your home network without
having to purchase more IP addresses from your ISP.
PC Card - This is an Ethernet card that connects to the PCMCIA slot on
your Notebook PC. This enables the computer to communicate with wireless
access points.
