WAN has a data transmission speed of 256Kbps to 2Mbps, offering a faster speed than LAN or MAN. WAN is used to connect LANs that are not in the same area and is more expensive than LAN or MAN. MAN is the abbreviation for Metropolitan Area Network and bigger than LAN network. It connects computer users that are in a specific geographical area. Definition of wide area network (WAN) Wide area network (WAN) is a type of network that provides transmission of voice, data, images, and videos over the large geographical area. WAN is made with the combinations of LAN and MAN. The transmission of data is carried out with the help of hubs, switches, fiber optics, modem, and routers. To transfer data from any computer over the internet we use.

Definition MAN
Metropolitan area network or shortened by MAN. A network in a city with high speed data transfer, which connects various locations such as campuses, offices, government, and so on.

A network in a city with high speed data transfer, which connects various locations such as campuses, offices, government, and so on. MAN network is a combination of several LANs. The MAN range of between 10 to 50 km, MAN this is the right network to establish a network between offices in the city between the factories / establishments and headquarters that are within his reach.
MAN advantages:
MAN can cover a wider area than a LAN. MAN networks are usually operated at airports, or a combination of several pieces at a local school. By running a large network connectedness, information can be disseminated more widely, rapidly and significantly. Public libraries and government agencies typically use a MAN.
Disadvantages MAN:
MAN will only apply if the personal computer or a terminal can compete. If a personal computer is used as a terminal, move the file (file transfer software) allows users to retrieve files (downloaded) from the hose or hose to deliver the data (upload). Download files means open and retrieve data from a personal computer to another and deliver the data to the computer pertaining requested by the user.

Network is a medium that connects multiple computer systems with a common communication link. A network is categories into three types such as Local Area Network (LAN), Metropolitan Area Network (MAN) and Wide Area Networks (WAN). And in this article, we will cover all about Wide Area Networks (WAN).

Wide Area Network (WAN)

A Wide Area Network (WAN) is a computer network that connects computers within a large geographical area comprising a region, a country, a continent or even the whole world.

Wide area networks, generally called WANs, are mostly public, leased or privately-owned networks. They provide a useful way of sharing resources between the end users such as the long-distance transmission of data, voice, image, and information over large geographical areas. The best example of a Wide Area Network is the Internet which connects many smaller LANs and MANs through Internet service providers.

The key difference between WAN and LAN

One key difference between a LAN and a WAN is that LANs are built, owned and operated by individual companies and organizations but unlike LANs, WANs are owned by third-party service providers a company wanting to connect its geographically dispersed LANs must subscribe to a WAN service providers such as a telephone company to use or lease it’s WAN carrier network services.

Another key difference between WANs and LANs technologies is scalability. Wide Area Network as its name suggests it must be able to grow as needed to cover multiple cities, even countries, and continents whereas Local Area Network as its name suggest it is able to cover single campus, single office, or a single building.

Typically, WANs are interconnected LANs. One of the best examples of a WAN is the Internet (a WAN that grows larger day by day).

Types of WAN Connections

A WAN (Wide Area Network) network can be established in many ways but there are two main types of WAN connections.

Dedicated Connection
Switched Connection

Dedicated Connections

A dedicated connection is a communications medium or other facility dedicated to a particular application such as telephony operation or internet service providing.

1: Leased Lines:

It is a dedicated point to point connection which provides pre-establish WAN communication path through Internet Service provider to a remote destination.
Leased Lines provides very high-speed data transmission up to 64Gbps.
It is very expensive.

2: Digital Subscriber Line (DSL):

It provides the connection between ISP to a customer through a telephone line.
It is a broadband technique which provides the same upstream and downstream.

3: Asymmetric Digital Subscriber Line (ADSL):

ADSL is a type of modern digital subscriber line technology, that enables data transmission at high speed over the telephone line.
It is the same as a digital subscriber line but the only difference is that upstream and downstream occurs at different time.

Switched Connections

There are three basic types of switched connections:

Circuit Switched Network.
Packet Switched Network.
Cell Switched Network.

1: Circuit Switched Network:

In circuit switches network every time before transferring data over the Wide area network, the new connection gets setup, after the data transfer the connection gets closed.
In this technique generally, data is transferred through a single connection or single path.

2: Packet Switched Network:

Packet switched network uses the virtual connection for transferring of information, first it creates a connection for data transmission and used it as a permanent connection.
It is faster than the circuit switched network.
It is used for multipath communication.

3: Cell Switched Network:

Cell switching operates in a similar way to packet switching but in this type of network data transfer is in fixed size which is up to 155 Mbps.
Cell switching can handle multiple data types, i.e. audio, video and image data.
ATM is the example of Cell switched Network.

The distinguishing features of Wide Area Network:

Covers large geographical area: Wide area network covers a large geographical area of more than 1000km. If your office is in different cities or countries then you can connect your office branches through Wide Area Network.
Centralized data: Wide area networks also provide you the facility of sharing the data to all of your connected devices in a network.For example, through WAN connection all office branches can share the data through the head office server. You can get back up, support, and other useful data from the head office and all data are synchronized with all other office branches.
Get updated files and data: Wide Area Networks provide you the facility of getting updated files and data from the server. If a server is updated with new data then all connecting devices receive that updated data within seconds.
Sharing of software and resources: Like LANs, we can share software applications and other resources with other users on the internet.
High bandwidth: WANs covers a large geographical area of more than 1000km. therefore WANs have high bandwidth compared to LANs and MANs.
