Networks can be classified in different ways, and each type has a specific purpose. The main classifications are based on size and how far the network reaches.
1. LAN (Local Area Network)
A LAN is a small network, usually inside one building like a home, school, or office. Its purpose is to let nearby devices,like computers and printers connect and share information quickly.
2. WAN (Wide Area Network)
A WAN covers a much larger area, like multiple cities or even countries. The internet is the biggest example of a WAN. Its purpose is to connect LANs together so people can communicate over long distances.
3. MAN (Metropolitan Area Network)
A MAN is bigger than a LAN but smaller than a WAN. It usually covers a city or a large campus. Its purpose is to connect several LANs within the same region.
4. PAN (Personal Area Network)
A PAN is the smallest network. It’s usually just around one person, like your phone connecting to your earbuds or smartwatch through Bluetooth. Its purpose is to support close range, personal device connections.
Overall, each network classification is based on how big the area is and how many devices need to communicate. They all exist to help people share data, communicate, and access resources easily.
