What is a Local Area Network (LAN)?

A Local Area Network (LAN) transmits data between computers in a small geographic area, usually a home, office, or building. A networked home computer can be used to connect to the Internet, play games, and share files with other computers on the LAN.

How to setup a Local Area Network (LAN)?

In order to set up a LAN, you will need a router, which connects the computers on the network to the Internet. You will also need a modem, which is a device that connects the router to the Internet. The modem connects to the Internet via a telephone line, cable, or DSL line.

Most routers come with a built-in modem, so you will only need to purchase a modem if you do not have a router. You can purchase a router and modem separately, or you can purchase a router with a built-in modem.

Once you have a router and modem, you can connect the computers on your Local Area Network (LAN) to the router using Ethernet cables. Each computer on the LAN will need its own Ethernet cable. The Ethernet cables connect the computers to the router, and the router connects the computers to the Internet. 

Connectivity of LAN:

You can also connect wirelessly to the Internet using a wireless router. A wireless router is a router that has a built-in modem and a wireless network card. A wireless network card is a card that is installed in the computer and allows the computer to connect to the Internet wirelessly.

Types of Local Area Network (LAN)

As technology advances, the need for networking increases. There are different types of Local Area Network (LAN) systems that are available, each with its own advantages and disadvantages. The three most popular types of LAN systems are Ethernet, Token Ring, and Fiber Distributed Data Interface (FDDI).

Ethernet is the most widely used type of LAN. It is fast, easy to install, and compatible with a wide range of devices. However, it is not as reliable as other types of LANs and can be subject to interference from other electronic devices.

Token Ring is a type of LAN that is more reliable than Ethernet but is more expensive and difficult to install. It is also not as compatible with a wide range of devices.

FDDI is a type of LAN that is very reliable and fast but is very expensive. It is also difficult to install and is not as compatible with a wide range of devices.

Benefits of Local Area Network (LAN)

A Local Area Network (LAN) is a network that connects devices within a small area, like a home, office, or school. LANs are usually cheaper and easier to install and manage than other types of networks.

There are many benefits of using a Local Area Network (LAN). One benefit is that LANs can be used to share resources, like printers and files. This can save money and time, because users don’t have to purchase their own resources. Another benefit is that LANs can provide better security than other types of networks. This is because only users on the LAN can access the resources on the network.

LANs can also improve communication. For example, users can use LANs to chat with each other or send files. This can be helpful for collaboration, since users can easily share information.

Overall, LANs can be very beneficial for homes, offices, and schools. They can save money and time, improve communication, and provide better security.
