What are the different types of computer networks?

Computer networks can be classified in various ways based on their scale, connection method, functional relationships, and their topology. Here’s a breakdown of some of the most common types:

1. Personal Area Network (PAN): A network that is used for personal or individual use, typically within the range of an individual person. For example, devices connected via Bluetooth, like a smartphone linked to wireless headphones.

2. Local Area Network (LAN): A network that connects computers within a limited area, such as a home, school, or small business. They are often connected using Ethernet cables. For example, computers in a business office connected to a single server.

3. Wide Area Network (WAN): A network that spans a large geographic area, often connecting multiple LANs. For example, the internet itself is the largest WAN. Another example might be a large corporation that has offices in different cities or countries and connects them using the internet or a private network.

4. Metropolitan Area Network (MAN): A network that covers a larger geographic area than a LAN but is smaller than a WAN, typically spanning a city or a large campus. For example, a network that connects various city government buildings or the network infrastructure of a university campus.

5. Wireless Local Area Network (WLAN): A type of local area network that uses high-frequency radio waves to communicate, eliminating the need for wired connections. For example, Wi-Fi networks in homes, cafes, or airports.

While these are just five types, there are other networks and classifications based on their architecture, topology, functional relationships, and more.
