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.
