A description of a Local Area Network (LAN) in an office setting, and a Wide Area Network (WAN). Businesses and other organisations often link computers together to make communication more efficient. Each computer is linked to a central server which acts as a go-between within this LAN and beyond. A WAN links computers together over a wide geographical area. The internet is the ultimate WAN. Browsers are software packages which allow you to navigate around the internet.

Classroom Ideas

Students could be asked to draw diagrams of a typical LAN and WAN. Split the class into groups of three people to discuss and answer the following questions, with each member of the trio presenting their answer to the class: What are the differences between these two networks? What are the advantages and disadvantages of each? Where and why would you use one instead of the other?
