WAN Full Form

A WAN (Wide Area Network) is to connect multiple smaller Local Area Networks (LANs). It is a computer network designed. WANs can help in communication, the sharing of information, and much more between systems or devices from around the world through a WAN provider.

What is a WAN?

WAN stands for Wide Area Network. It is a computer network that covers a large geographical area consisting of two or more LANs or MANs. These networks are established with leased telecommunication circuits, in which two sides which are connected have routers that connect the LAN of both sides together in a network to facilitate communication.

History of WAN

The roots of WAN are connected to the U.S Department of defense which developed ARPANET to let researchers communicate and share computer resources remotely. The connection can be circuit-switched telephone lines, radio wave transmission or optical fiber transmission. It is used to exchange data with users all over the world, they can be client, employee, buyer, seller, student, etc. WAN has the ability to transmit data, image, audio data, video data over large distances.

What is a WAN Router?

An organisation can access a carrier network by using a WAN router, sometimes referred to as an edge router or border router, which routes data packets between WAN locations. Packet over SONET/SDH (PoS), Multiprotocol Label Switching (MPLS), ATM, and Frame Relay are many WAN protocol were developed.

FAQs On WAN(Wide Area Network)

Q.1: What is WAN-as-a-service?

Answer:

One type of cloud-based WAN model is WAN-as-a-service. WAN-as-a-service options are intended to take the place of legacy WAN arrangements, which are hard to scale up, rely on hardware, and require communication protocols like multiprotocol label switching (MPLS). Due to WAN-as-a-Service being provided via the cloud, only customers need Internet connectivity and using software, configure their WAN.

Q.2: What are the classification of WAN?

Answer:

There are 5 types of WAN classifications as shown below.

Q.3: What is a leased line?

Answer:

Leased lines is one method by which organizations link their LANs to create a WAN. An ISP or other major network provider will rent you a leased line, which is a direct large network connection. For most organisations, it would be nearly impossible to build their own physical network infrastructure, which would include cables, routers, and Internet exchange points spread across hundreds or thousands of kilometres. Instead, they contract with a business that already owns this infrastructure to lease a direct, dedicated connection.
