Hey, Do you want to know The Difference between LAN and WAN? Then follow this article.

What is a LAN(Local Area Network)?

A local area network (LAN) is a collection of such devices as Computers, Printers, Switches, Routers, etc, that a connected together in one physical location, such as a building, office, or selected area. A LAN can be small or range depending on your requirements.

If you are using it at home it can be one to two users. If you are using LANs such as schools, colleges, and Offices Quarters it can be a thousand and above users.

Local Area Network is the key point of Networking that allows the user to connect his resources like Firewall, Switches, Routers, etc connected to the internal Server. In the Local Area Network, you can share your resources like Printer, Storage, Local Web services, etc.

Local Area Network allows computer System Administrator to multiple functions For example, in an office with multiple departments, such as accounting, IT, Human Resources, Sales Department, Marketing, and administration, each department’s computers could be logically connected to the same switch but the help of VLAN to behave as if they are separate.

Local Area Network is allowed to give benefits of resource sharing such, as high reliability, cost benefits, and scalability.

For example, In your office group of devices connected together with the help of the Local Area Network, you can access the Internet on all the devices from a single connection the Internet, likewise, Printers, File servers, etc. are accessed and controlled by one another.

What is a WAN(Wide Area Network)

A Wide Area Network is also known as WAN. WAN is a large network of connections of multiple resources or devices that can be accessed from single points of the location. WANs can allow facilitating communication, the sharing of information, resources, and much more between devices from around the world through a WAN provider.

Wide Area Network provides no limit to the distance you can get access to information from any location. In most WANs, You can access your network consisting of two distinct components circuits or channels or links and switching and routing devices (switches & routers).

Transmission lines are used for moving data between machines, whereas routers are used to connect two or more transmission lines. With the help of the Wide Area Network, users can access resources for long-distance transmission of data, voice, image, and video information over large geographical areas that may comprise a country, a continent, or even the whole world.

The main purpose for Wide Area Network As organizations grow and become international Plateform, WANs allow them to communicate between branches, share information, and stay connected. When employees travel for work, WANs allow them to access their information or networks from any location in the world via VPN with the help of the Internet or satellite.

However, WANs also provide an essential service to the public. For example, you can access your bank account details from any branch location. Students can access their research information from anywhere.

What is the difference between LAN and WAN?

The main difference between LAN and WAN are the following:-

S.N.	LAN	Key	WAN
1	Stands For Local Area Network.	Stands For	Stands for Wide Area Network.
2	LAN Range Up to 10 KM.	Range	WAN Range Up-to Globally.
3	LAN Speed is quite high because it covers offices, buildings, or Connected Locally.	Speed	WAN Speed is Quite Low because it’s over different branches connected Remotely.
4	Easy to Setup rather than WAN.	Setup	Difficult to Setup rather than LAN.
5	LAN has Low congestion because it’s used some in range.	Congestion	WAN has High Congestion because it’s used globally.
6	The Implementation and designing of LAN is easy and less costly rather than WAN	Maintenance	The Implementation and designing of WAN are Costly rather than WAN
7	LAN Supports Layer 2 Devices like a switch, Hub, Bridge, etc.	Components	WAN Supports Layer 3 Devices like Router, Multilayer Switches, etc.
8	LAN fault tolerance is high rather than WAN.	Fault Tolerance	WAN fault tolerance is low rather than LAN.
9	Any Office Building or Showroom.	Example	Different Branch of Banks.
