MAN(METROPOLITAN
 
AREA
 
NETWORK) 
MAN is a computer network that merges different networks situated in various buildings into a single network. The range of this 
network lies between 5 to 50 kilometres. The geographical area of MAN lies between LAN and WAN i.e. it covers more area than 
LAN but less than WAN. MAN network can be wired as well as wireless.[8] It connects various LAN's covering the entire city. 
Various computers in wired MAN can be connected using different communication mediums such as: a twisted pair, optical cables 
and in wireless MAN with the help of radio waves etc. [12] Example of MAN network : Network between different branches of a 
bank in a city, cable television networks, air reservation.[1][2][3][18][14]

V. CAN
 
(CAMPUS
 
AREA
 
NETWORK) 
It is a type of network built upon connection of various LAN networks within restricted geographical area. It is also known as 
corporate network.
These 
are interconnected with high speed Ethernet using optical fiber. The range of CAN varies from 1 km to 
5 km.Network can be said to be CAN network if two same domain buildings are connected with a network. Example of CAN 
network: Any campus or university network such as the Stanford University Network at Stanford University.[1][2][3][6][15]

VI. WAN(WIDE
 
AREA
 
NETWORK) 
WAN i.e. wide area network is the connection of devices allowing communication over wide area i.e. covering a state, country even 
continent. Connecting devices in WAN network can be switches, routers, modems etc. WAN contains collection of hosts which are 
connected by a communication subnet which carries message from host to host. Mostly different people own and operate hosts and 
subnet. Transmission lines and switching elements are the components mostly found in WAN network. Transmission lines can be 
copper wire, optical fiber, radio waves etc. Switching lines popularly known as routers provides connection between these

transmission lines. Due to large area covered in this network leads to propagation delay, low data rate problems. Example: Bank 
with different branch offices in different cities. In the following diagram WAN connects the three branch offices of Diskon, St. 
Petersburg, Magadan in Russia..[1][2][3][8][18][10]
