10 Advantages and Disadvantages of WAN | Drawbacks and Benefits of WAN

In this post, we are going to learn 10 advantages and disadvantages of WAN network | Drawbacks and benefits of WAN with meaning, description, and examples.

When one or multiple computers, or devices are connected with each other for the purpose of data and internet sharing this technique or method is known as Networking.

The networking can be performed with the help of wired or wireless.

The wired network can be established with the help of twisted cables, coaxial cables, optic fiber, switches, routers, hubs, etc.

The wireless network can be established with the help of wireless devices, radio wave, Bluetooth, infrared, etc.

A network can be explained in simple words as a group or collections of computers, laptops, and devices connected with each other where they share resources, data, pieces of information, and instructions.

The computer which is connected to the network is usually called a node.

The WAN Stands For Wide Area Network.

What is WAN in Computer Network with Examples?

The WAN {Wide Area Network} is a network that covers a large area for providing internet services around regions, countries, and across continents.

The WAN (Wide Location Network) is a network that covers a big geographical location that can cover an area, nation, continent, or whole globe.

The Full Form of WAN is a Wide Area Network.

It is a network that provides long-distance transmission of data, voice, images, video, and any type of information transmission over a large geographical area with different LANs {Local Area Network} and MANs {Metropolitan Area Network}.

WAN can connect devices from multiple locations along the world are the form of a telecommunication network.

WAN is the most extensive range of computer networks that people use today.

We take the internet as an example of WAN as the web spreads around the world.

The user utilizes this network to store information or interact with the individual regardless of where the customer is long-distance or anywhere in the world.

They access it through the WAN.    

WAN networks could connect a LAN with the other LANs using telephone lines and radio waves and are mainly limited to an enterprise or organization.

  • The Software developer can work online on a live web project where certain data and information are needed from other resources present in other countries. In this type of situation, the WAN network plays an important role.
  • The internet can also provide business opportunities like e-commerce websites, blogging, video blogging, trading, etc.
  • Online education is the primary and best advantage of WAN.
  • The WAN network provides incredible speed as its bandwidth is high.
  • The updates and upgrades of software and applications are very easy and efficient.
  • The data and information are stored in a centralized network.
  • Due to WAN world had become a global village.
  • Worldwide connectivity had played an important role in the advancement and enhancement of local as well as international business.
  • People around the globe are interconnected with each other thanks to the social networking websites like WhatsApp, Facebook, Instagram, etc.
  • The files and folder can be easily shared through the WAN network from one part of the world to other.
  • This type of network saves money as well as our precious time as it can handle important tasks and jobs with incredible speed and security.
  • Wide Area Network has helped many starts to grow their business globally and also increased their work efficiency.
  • The wide area network has also helped businesses in transportation, computer networking, the software industry, the hardware industry, etc.
  • Their ownership can be public or private.

Disadvantages of WAN in Computer Network

  • The WAN network is a huge network therefore maintaining this kind of network is a herculean task.
  • The primary disadvantage of WAN is they are expensive compared to other networks.
  • The peripherals and devices require for the initial installation of the WAN setup is too expensive.
  • The WAN is a combination of various other technologies, therefore, has many security issues compared to MAN and LAN
  • The WAN networks are incredibly huge therefore their maintenance and initial setup Is very complex.
  • The WAN networks need software as well as a hardware firewall and legal antivirus software for data security against hackers and crackers. As these networks are prone to get hacked.
  • As WAN covers many areas, fixing the problem in it isn’t easy. Most of the WAN wires go into the sea, and wires get broken sometimes, so it requires lots of money to fix lines under the sea.
  • To fix or resolve network issues we need professional help which sometimes can be really expensive.
  • In some areas, internet standard protocol faces problems due to electric supply or bad lines structures from this customer often faces connectivity issues or slow internet speed issues.
  • Connectivity issues can occur. The WAN networks are very difficult in addressing the issue.
  • If the network goes down the complete setup crashes which can be frustrating sometimes.
  • The Speed of WAN is slower than LAN.
  • The propagation delay time in WAN is longer.
  • The design of the WAN Networks is more complex compared to their counterparts.
  • WAN networks have a lower data transfer rate.

What are the Different Applications of WAN?

The WAN networks are primarily used for military services.

The military setups are highly confidential therefore these networks are used due to their silent features like speed, accuracy, less vulnerability, and very efficiency in use.

These networks are highly secure from hackers.

The WAN networks are used in railway tickets and reservations and are also prominently used in airline tickets.

These networks are centralized and are able to cover large geographical areas for communication.

Due to their centralized database, anyone can book tickets from anywhere in the world.

WAN networks are used in the centralized development of resources, data, and information sharing.

What are the Features of WAN?

WANs have a large capacity, connect many computers over a large area, and are inherently scalable.

They facilitate the sharing of regional resources. They provide uplinks for connecting LANs and MANs to the internet.

Public carriers provide communications links like telephone networks, network providers, cable systems, satellites, etc.

Typically they have low data transfer rates, and high propagation delay means they have low communication speed.

They generally have a higher bit error rate. 

Best Examples of WAN

The WAN is a network in which different local Area Networks are connected to each other to establish better communication.

LAN networks use routers, switches, and cables for establishing connections.

An example of a Wide Area Network is the internet. On the internet, we can transfer files from one computer to another.

The Banks are the best example of WAN. LANs are often connected to WAN; a school network could be connected to the internet.

WANs can be connected using the internet through a leased line or satellite links.

ATMs are considered to be the best examples of WAN Networks. University libraries are also a good example of WAN.
