What Is a LAN

LAN is called the Local Area Network. LAN can be connected within a specified area or small area. Small areas can be schools, colleges, and offices, etc. LANs are also known for privately owned networks. Because of this, LAN resources are shared easily among end-users. Printers, files, internet sharing, along with other computers, is easily done.

Local Area Network (LAN) is a group of network devices connected together like offices, schools, buildings, etc. LAN has a good security network as there is no association with outside networks and no interruptions due to outside networks in the Local Area Network.

Hence, the data present on the local area network is completely safe, and outsiders cannot access it. LANs are occupied within small geographical areas, so they are much faster, speed varies from 100 to 100Mbps. LANs do not necessarily have to be wired networks; there are also LANs that come with wireless networks.

What’s in a LAN?

Local Area Network (LAN) consists of some devices such as cable wire, switches, routers, access points, etc., along with they also require devices that are connected to internal servers and web servers. And if you want to communicate with other LANs, then they can also be connected. Within a small geographical area, many LANs can be interconnected with each other.


LAN provides you good data security, and sharing of resources is easily and safely done among the connected LAN users.

What are The Benefits of a LAN?

LAN network comes with some benefits for you. Resource sharing is easily done. Modems, printers, scanners, internet, and hard disks can be shared using one LAN network with connected devices. Because of the sharing of resources hardware cost can be reduced.

Software application sharing is also possible. The same software can be used for connecting many computers to a network. Sharing of the software will save you from buying newly licensed software for specific client needs. Communication is very easy and can be done with a small amount of money.

Messages and data can be sent to other devices easily that are connected with the same network. There exists a central computer that consists of a hard disk where all the data are stored on all the networks.

So, if the users want their data they can access that data from any computer network that is connected to the central computer. Data security is given by the LAN network. As all the data is stored in the central hub network so it is safe.

Local Area Network (LAN) helps to connect many other computer devices or LAN users using a single internet connection. In the cafe, in school, in offices, or in the buildings also Local Area Network ( LAN ) can be used.

Are There Different Types of LANs?

Yes, there are 2 types of LANs Local Area Networks which are client/server, and peer-to-peer LANs local area network.

1. Client/Server Local Area Network (LAN)

Client/Server means nothing but all the client devices are connected to the central server. The work of the server is storing files, looking after application accesses, managing network traffic, and if any devices need access to provide it. The Clients devices must be doing any task like accessing the application or running anything on the internet.

The clients can reach the server via a wired connection or through a wireless connection.

Users on the LAN network have the advantages of accessing the database, can share the document, emails, printer usage, and many other advantages. While there are also other services running on the LAN network that have read and write access and that are managed by a network or IT administrator.

Client/Server LANs consist of mostly large businesses, government, research, and education networks.

2. Peer-to-Peer Local Area Network (LAN)

Peer-to-peer is comparatively smaller than the client/server LANs. All the data is not stored in the central server, because peer-to-peer does not consist of the client-server. Also, Peer – to – peers are not used to handling heavy loads of data. All the connected devices in the Peer – to – peer network have equally distributed functions.

The sharing of resources between devices happens with the help of a wired network or wireless network. Peer-to-peer LANs networks are majorly connected at home.


That is all about the LAN network and the benefits you get from it. Many LAN networks can be interconnected via a single central / server. Data security is good. As the LAN network is cheap hence, communication can be easily done without any outer network interface.

LAN network can be accessed only by LAN users also, outsiders cannot use that data. Hope this article was helpful for you. Have a good read. Let me know if you have any doubts. See you, until next time! Ciao!
