WAN vs LAN | Difference between LAN and WAN?

Hello friends, in this article, I am going to show the basic differences between LAN and WAN networks in computer networking.

What is LAN?

  • A Local Area Network is a privately owned computer network covering a small geographical area like a home, office, building, or a school network etc.
  • The LAN is used to connect the computers and other network devices so that the devices can communicate with each other to share the data and resources.
  • They are widely used in the business organization, factories, colleges, university, industry to sharing resources such as files or hardware devices etc.
  • Bus and Ring Topology are generally used. In LAN, network range is 10 m to 100 m.

What is WAN?

  • A Wide Area Network is a type of telecommunication network,
  • A WAN network is used for communication between different devices of a large geographical area such as large cities, countries or continent etc.
  • A WAN network can contain multiple smaller networks, such as LANs or MANs.
  • The Internet is the best example of the WAN network,
  • The speed of WAN networks varies depends on the cost of the companies.

Difference between LAN and MAN?

S.No.LANWAN
1The LAN network is owned by a person, college, factory etc. It is a privately owned network.WAN network can be private or it can be public leased type network.
2LAN is designed to operate over a small physical area such as office, factory or group of buildings.WAN is used for the network that spans over a large distance such as system spanning states countries etc.
3LANs are easy to design and easy to maintain.WAN is not so easy to design and maintain .
4The communication medium used for interconnection is a simple co-axial cable in LAN network.The communication medium used in WAN can be PSTN or satellite links due to longer distances involved.
5Due to shorter distances, problems such as propagation delay do not exist. So, LAN can be used for time critical.Due to long distances involved, the problems such as propagation delay, variable signal travel time applications, do exist. So, WAN can’t be used for the time critical applications.
6LAN network can operate on very high data rates.WAN network operates on low data rates.
7In a LAN each station can transmit and receive over the communication medium.In WAN, each station can not transmit.
8 Local area network operates on the principle of broadcasting.WAN operates on the principle of switching.
