Types of networks
Networks[1]
There are different types of networks. Common types of networks are: WAN and LAN. There are other types of networks as well: SAN, MAN, BAN, IAN and others. Each network type helps us understand the purpose, design goals, and scale of the network. For example if we say a network is a LAN, we can assume it is a local network, probably in one building or in a reasonably restricted area. We might make an assumption that a LAN has a certain number of devices connected to it. However, if we say a network is a WAN, we might assume it is much larger, and designed to accommodate a much, much larger number of devices.

Do you understand this topic?[edit]
You should be able to:
- Describe how communication over networks is broken down into different layers.
- List the stages in the OSI model
Do you have an advanced understanding about this topic?[edit]
If you want an advanced understanding of this topic, try answering the questions below:
- Explain the process of encapsulation and de-enacapsulation
- We use the OSI model to help us understand where to look for problems. Describe what tools you would use to diagnose which levels of the OSI model.
