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 network of end stations (such as PCs, printers,
	servers) and network devices (hubs and switches) that cover a relatively
	small geographic area (usually not larger than a floor or building). LANs
	are characterized by high transmission speeds over short distances (up to
	1000 metres).
MAC	Media Access Control. A protocol specified by the IEEE for determining
	which devices have access to a network at any one time.
MAC Address	Media Access Control Address. Also called the hardware or physical
	address. A layer 2 address associated with a particular network device.
	Most devices that connect to a LAN have a MAC address assigned to
	them as they are used to identify other devices in a network. MAC
	addresses are 6 bytes long.
MTU	Maximum Transmission Unit is the size of the largest datagram that can
	be sent over a network
NAT	Network Address Translation. NAT enables all the computers on your
	network to share one IP address. The NAT capability of the Router allows
	you to access the Internet from any computer on your home network
	without having to purchase more IP addresses from your ISP.
Network	A Network is a collection of computers and other computer equipment
	that are connected for the purpose of exchanging information or sharing
	resources. Networks vary in size, some are within a single room, others
	span continents.
Network Interface	A circuit board installed into a piece of computing equipment, for
Card (NIC)	example, a computer, that enables you to connect it to the network. A
	NIC is also known as an adapter or adapter card.
Protocol	A set of rules for communication between devices on a network. The
	rules dictate format, timing, sequencing and error control.
