Classes of network
1. Local Area Network (LAN): A LAN is a network that covers a small geographical area, typically within a single building or campus. It is used to connect devices like computers, printers, and servers within a limited range.
2. Wide Area Network (WAN): A WAN is a network that spans a large geographical area, such as cities, countries, or even continents. It connects multiple LANs and enables communication between devices that are located far apart.
3. Metropolitan Area Network (MAN): A MAN is a network that covers a larger geographical area than a LAN but smaller than a WAN. It is designed to connect different LANs within a city or metropolitan area and provides high-speed connectivity.
4. Storage Area Network (SAN): A SAN is a specialized network that is used to connect storage devices, such as disk arrays and tape libraries, to servers. It allows for centralized storage management and provides fast and reliable access to data.
5. Campus Area Network (CAN): A CAN is a network that connects multiple buildings within a college campus or corporate campus. It provides high-speed connectivity and enables seamless communication between different locations within the campus.
6. Virtual Private Network (VPN): A VPN is a network that allows users to securely access a private network over a public network, such as the internet. It provides a secure and encrypted connection for remote users to access resources on the private network.
7. Wireless Local Area Network (WLAN): A WLAN is a wireless network that uses radio waves to connect devices within a limited range. It is commonly used for wireless internet access in homes, offices, and public places.
8. Personal Area Network (PAN): A PAN is a network that connects personal devices, such as smartphones, tablets, and wearable devices, within a small area. It allows for easy communication and data sharing between personal devices.
9. Peer-to-Peer Network: A peer-to-peer network is a decentralized network model where devices share resources and communicate directly with each other. It does not rely on a central server and is commonly used for file sharing and collaboration.
10. Internet of Things (IoT) Network: An IoT network is a network that connects various physical devices, sensors, and actuators to exchange data and perform tasks. It enables devices to connect and communicate with each other, leading to the development of smart homes, cities, and industries.
