What are the Types of Computer Network?

There are four (4) types of network, and these are:

PAN (Personal Area Network) is a computer network that enables communication between  computer devices near a person. PANs can be wired, such as USB or FireWire, or they can be wireless such as infrared, Zigbee, Bluetooth, and ultrawideband (UWB).

LAN (Local Area Network) is a group of computers and associated devices that share a common communications line or wireless link to a server. Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as a networked office building, school, or home though sometimes one building will contain a few small LANs (perhaps one per room). In short, a LAN connects network devices over a relatively short distance.

MAN (Metropolitan Area Network)  is a computer network that interconnects users with computer resources in  a geographic area or region larger than that covered by even a large local network but smaller than the area covered by a wide area network.

WAN (Wide Area Network) is a  network that exists over a large-scale geographical area. A WAN connects different smaller network including LANs and MANs. This ensures that computers and users in one location can communicate with computers and users in other location.
