ISP Gateway Address:
(see ISP for definition). The ISP Gateway Address is
an IP address for the Internet router located at the ISP's office.
ISP:
Internet Service Provider. An ISP is a business that provides connectivity
to the Internet for individuals and other businesses or organizations.
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:
MAC stands for Media Access Control. A MAC address is the
hardware address of a device connected to a network. The MAC address is a
unique identifier for a device with an Ethernet interface. It is comprised of two
parts: 3 bytes of data that corresponds to the Manufacturer ID (unique for each
manufacturer), plus 3 bytes that are often used as the product’s serial number.
NAT:
Network Address Translation. This process allows all of the computers
on your home network to use one IP address. Using the broadband router’s
NAT capability, you can access the Internet from any computer on your home
network without having to purchase more IP addresses from your ISP.
