When we talk about a network, that could be anything connecting two or more devices. It’s important we understand the different types of networks. Networks are broken into different subsets based on their size and function. Here are some of the most common network types:
A Local Area Network (LAN) is a smaller network that connects multiple devices in a limited area. Examples of LANs include small offices, a home, or any other network contained within a small area.
A Campus Area Network (CAN) connects multiple computers and devices over a slightly larger area. In many cases, these types of networks will connect multiple buildings located in the same vicinity. You may see these networks in a university where multiple buildings and outdoor spaces provide students with network access.
A Wide Area Network (WAN) connects multiple computers over a geographically large area. Large, international organizations may operate these types of networks. To ensure that computers spread over large regions are able to communicate, companies may use a VPN (Virtual Private Network) to connect systems securely. A VPN can allow systems across large regions to connect and interact with one another on the same network.
Since we’re all connected to the Internet, the whole Internet can technically be classified as a WAN!
