Understanding PAN, LAN, MAN, and WAN Networks

The video discusses PAN, LAN, MAN, and WAN networks.

A network is composed of three types of physical components: endpoint devices, network equipment, and data transport.

Endpoint devices include computers, printers, and servers, while network equipment includes switches and routers.

⚡️ Different types of networks: PAN, LAN, MAN, WAN

📶 PAN is a personal network that connects devices in the same room

🔌 LAN is a local network that covers a restricted geographical area

🏢 A LAN is a local area network that allows multiple computers to share files and network resources within a building or institution.

📡 A wireless LAN (WLAN) enables devices to connect within a hundred meters using radio waves, with WiFi being the most commonly known type.

🌆 A MAN is a metropolitan area network that connects nearby LANs as if they were part of the same network, typically covering an entire city.

🌐 A WAN is a wide area network that spans long distances and is used on a larger scale, such as connecting multiple cities or even countries.

🌍 A WAN allows the interconnection of multiple LANs over long distances, like the internet.

🔗 International organizations can create private WANs, such as banking networks or stockbroker networks.

📡 WANs utilize fiber optic infrastructure, international submarine cables, or satellite transmission.
