Answer:
types of computer network:
1. lan (local area network) :
a local area network is a computer network covering a small area like a home, office, or a group of buildings such as a school or college.
a simple LAN can consist of of a personal computer and a printer or it can connect several computers together.
a Lan is limited in size, typically spanning a few hundred metres.
it is usually fast, with speeds from 10 mbps to 10 gbps.
it requires little wiring, typically a single cable connecting to each device.
its setup involves lower cost compared to man's or wan's.
lan's can be either wired or wireless.
2. man (metropolitan area network)
a man is a network covering a large area like a campus, offices, city.
it is used for interconnection of several lan's.
a MAN is a high speed network and allows sharing of multiple resources. eg:cable tv network, dsl
3.wan (wide area network)
a wan connects lan and man together.
it covers a very large area like a country or continent.
wan's may transmit data over high-speed phone lines or wireless links such as satellites.
internet is an example of wan
