Computer Science: OCR A Level, topic 3.3.3
Geographical Classification of Networks
Networks can be described by the geographical area that they cover.
Local area network (LAN)
- A LAN is a collection of computers connected over a small geographical area.
- These are typically found in homes, schools, universities, and small companies.
- The LAN is set up and maintained by the organisation that uses it.
Wide area network (WAN)
- A WAN is a collection of computers connected over a large geographical area.
- WANs are used by multinational organisations that have international offices they need to connect to.
- A WAN is usually rented from a large telecommunications company because WANs are expensive to set up.
- One example of a WAN that you use is the Internet. The Internet is the largest WAN in the world.
