Lesson 3 - Topologies

1. A Wide Area Network (WAN) is a network that covers a large geographical area such as an ATM machine or the Internet

2. A Local Area Network (LAN) is a network that covers a small geographical area such as your school network or a home

3. A Bus network is very cheap and simple to install but if the main cable fails, the whole network will fail

4. A Ring network is a one-way system so it is not affected by heavy traffic but if a cable fails anywhere in the network the entire network fails

5. A Star network has the fastest performance but the most cable so it is expensive to install
