Understanding WAN networks – WAN stands for Wide Area Network. WAN is used to describe a network that covers a very wide geographical area such as a city or country.

WAN networks are used for many purposes, for example for business purposes, education and also for government purposes because the function of this WAN network is to integrate many computers so that they are connected to each other in accessing information/data.

The following will discuss the definition, function, and how it works.

Definition of WAN Network
Wide Area Network (WAN) is a computer network that has a wide area coverage covering between cities, regions and even between countries to be able to communicate with each other and exchange data and information.

WAN network is not a new network concept because this WAN network has existed in the world since 1970. However, this concept is not a modern and latest network concept as it is today.
WAN network is the type of network that is most widely used in the modern era as it is today, as an example of using the internet network that connects one cell phone to another.
In addition, another example of this WAN network is the internet network used for cashiers and goods databases from minimarkets such as Indomaret and large supermarkets such as Carefour. In addition there are many more examples of the use of this WAN network.

WAN network characteristics

Among the many types of computer networks that exist today, what distinguishes them from one another lies in the characteristics they have. Then what are the characteristics of a WAN network? So a WAN network has the following characteristics:
. WAN is a network that is used to connect devices that cannot be reached by other networks such as LANs and MANs. This is due to the wide coverage area to be covered.
. WAN is also a network that is used to connect over long distances. This connection is also done using a serial connection that comes from various other types of devices.
. Can send data packets between switches, routers or between networks that have been built.
. To access bandwidth remotely, serial connections of various types are required.
. Is a network that works at the OSI layer at the physical layer and the data link layer.

WAN Network Functions

. Basically, the function of this WAN network is to connect one computer to another. However, for more detailed functions of this WAN network, among others are:
Integrate and connect LAN and MAN networks into one WAN network.
. Accelerate the flow of information and communication carried out in a wider network.
. Ensure a more efficient flow of information
. Prevent miscommunication
. Save more on costs used for operational purposes
. Support national and international company operations.

How WAN Networks Work
To find out how a WAN network works, the following will be explained in an example case:
. A company will select and place 1 server computer for its database access needs.
. Then the server computer will send database information and data packets to the entire network that has been built according to the topology
. With the network topology that has been built, the client computer or user can access all information to the server computer even though they are outside the island or even between countries.
