There are several types of networks, including Local Area Networks (LANs), Wide Area Networks (WANs), Metropolitan Area Networks (MANs), and Wireless Local Area Networks (WLANs). LANs are used to connect devices within a small area, like a home or office building, while WANs connect devices across large geographical distances. MANs are similar to WANs but cover a smaller area, typically a city. WLANs, on the other hand, use wireless technology to connect devices within a limited range.
