Some of the area networks that are commonly used include:
1. Local Area Network (LAN): A network that covers a small geographical area, such as a single building or campus.
2. Wide Area Network (WAN): A network that covers a larger geographical area, such as multiple buildings or cities, and typically connects multiple LANs.
3. Metropolitan Area Network (MAN): A network that covers a larger geographical area than a LAN but smaller than a WAN, typically within a city or metropolitan area.
4. Personal Area Network (PAN): A network that covers a very small area, typically within a person's personal space, such as connecting devices like smartphones, tablets, and laptops.
5. Campus Area Network (CAN): A network that covers a larger geographical area than a LAN but smaller than a MAN, typically within a university campus or corporate campus.
6. Storage Area Network (SAN): A specialized high-speed network that connects storage devices to servers, allowing for efficient data storage and retrieval.
7. Virtual Private Network (VPN): A network that allows users to securely connect to a private network over a public network, such as the internet, enabling remote access to resources and data.
