                        cover a larger area than a LAN but smaller than a WAN, such as a city or a large campus.

                         Covers a larger area than LAN                   More complex than LAN
                         High-speed connectivity across buildings        Needs specialised hardware

                         Cost-effective compared to WAN                  Security can be a concern
                         Wide Area Network (WAN): A WAN covers a much larger geographic area than a LAN or MAN. It
                        can span a city, country or even multiple continents, connecting multiple LANs together. The Internet
                        is the largest and most well-known example of a WAN, connecting millions of devices globally.
