Group work: discussion - What kind of computers have you used? Reading: When only a few computers are hooked together, usually in a single office or
building, the result is called a Local Area Network LAN. When the computers are connected over a greater distance, for example sales offices throughout a city, the result is called a Wide
Area Network WAN. Connecting all of these LANs and WANs together results in an Internet. The Internet is the world wide connection of all different kinds of networks. A new kind of
network is emerging for businesses called an intranet. This refers to all the computers in a company sharing data using the same kind of system as the Internet.
