Define types of Network?

What are the types of Computer Network?

A computer network is the interconnection of various computers located at different places. There are different types of network based on their size(Number of devices), data transfer speed and their reach. There are three main category of networks given below:-

• LAN

• MAN

• WAN

LAN:-


LAN stands for Local Area Network. It connects network devices on a short distance. It is group of computers which all belong to same organisation or building. It links the devices in a single office, campus and building. 
In LAN the data transfer speed can reach up to 10 Mbps for an Ethernet network and 1 Gbps for Gigabit network. It can be reach as many as 100 or even 1000 users. 


MAN:-


MAN stands for Metropolitan Area Network.It is a network that interconnects users with resources in an area larger than that of LAN area but smaller than a WAN area. A MAN is made from switches or routes connected to one another with high speed links. It spread over an entire city.  


WAN:-


It is a geographically-dispersed collection of LANs. It is more larger than LAN and MAN network. The speed varies on WAN depending on the cost of the connection. Computer connected to a WAN network are often connected through public network like telephone system. They can also be connected through leased line and satellites. WAN provides a long distance transmission of data, video,voice and image information over large geographical area like a country, continent or even the whole world. Internet is the most well known WAN network.
