There are four types of computer networks:1. LAN (Local Area Network) - a small network that connects devices within a limited area, such as a home, office, or small group of buildings.2. WAN (Wide Area Network) - a large network that connects devices over a large area, such as a city, state, country, or even the world. 3. MAN (Metropolitan Area Network) - a network used to connect devices within a specific geographic area that is larger than a LAN but smaller than a WAN. 4. PAN (Personal Area Network) - A PAN is created when two or more devices are connected in close proximity to each other.
