Prerequisite – Types of area networks – LAN, MAN and WAN
LAN stands for Local Area Network is a group of network devices which allow the communication between connected devices. The private ownership has the control over the local area network rather than public. LAN has short propagation delay than MAN as well as WAN. It covers the smallest area such as: College, School Hospital and so on.
MAN stands for Metropolitan Area Network. It covers the largest area than LAN such as:Small towns, City etc. MAN connects 2 or a lot of computers that area unit apart however resides within the same or completely different cities. MAN is expensive and should or might not be owned by one organization.
WAN stands for Wide Area Network. It covers the large area than LAN as well as MAN such as: Country/Continent etc. WAN is expensive and should or might not be owned by one organization. PSTN or Satellite medium are used for wide area network.
Let’s see that the difference between LAN, MAN and WAN:
|LAN stands for Local Area Network.||MAN stands for Metropolitan Area Network.||WAN stands for Wide area network.|
|LAN’s ownership is private.||MAN’s ownership can be private or public.||While WAN also might not be owned by one organization.|
|The transmission speed of LAN is high.||While the transmission speed of MAN is average.||Whereas the transmission speed of WAN is low.|
|The propagation delay is short in LAN.||There is moderate propagation delay in MAN.||Whereas there is long propagation delay.|
|There is less congestion in LAN.||While there is more congestion in MAN.||Whereas there is more congestion than MAN in WAN.|
|LAN’s design and maintenance is easy.||While MAN’s design and maintenance is difficult than LAN.||Whereas WAN’s design and maintenance is also difficult than LAN as well MAN.|
|There is more fault tolerance in LAN.||While there is less fault tolerance.||In WAN, there is also less fault tolerance.|
