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

your home network without having to purchase more IP addresses from your
ISP.
