Different types of networks serve varying scales and purposes in the realm of computer networking. A Local Area Network (LAN) is a network limited to a small geographic area, typically within a single building or campus. LANs facilitate high-speed communication between connected devices, enabling resource sharing and collaboration. Wide Area Networks (WANs), on the other hand, cover a larger geographical area, often spanning cities, countries, or even continents. WANs use various technologies, including leased lines and satellite links, to connect LANs over extended distances. They play a crucial role in interconnecting geographically dispersed offices or branches. Additionally, Metropolitan Area Networks (MANs) fall between LANs and WANs, covering a larger geographic area than a single LAN but smaller than a WAN, typically within a city. Understanding the distinctions between LANs, WANs, and MANs is fundamental for network design and administration, as each type serves specific connectivity needs based on the scale and requirements of the network.
