Introduction to Networking
2. Network Types
LAN, WAN, MAN, PAN
Networks are classified based on their geographical scope. Understanding these categories is crucial for designing and managing networks.
1. PAN (Personal Area Network): A network connecting devices within a very small area, typically for a single person. Examples include a Bluetooth connection between a smartphone and wireless headphones or a laptop and a wireless mouse.
2. LAN (Local Area Network): A network that connects devices within a limited geographical area, such as a home, school, or office building. Ethernet and Wi-Fi are the most common technologies used to build a LAN.
3. MAN (Metropolitan Area Network): A network that spans a larger area than a LAN, such as an entire city or a large campus. A MAN typically connects several LANs together.
4. WAN (Wide Area Network): A network that covers a broad area, spanning across cities, countries, or even continents. The internet is the most well-known example of a WAN.
