Summary

A LAN, which stands for Local Area Network, is a network of computers and devices that are connected together within a limited area, like a school or home. To set up a LAN, you need specific hardware components.

Firstly, each device requires a NIC, also known as a Network Interface Controller/Card, to connect to the LAN. These cards enable devices to communicate with each other using a common set of rules called protocols.

For wireless connections, a WAP (Wireless Access Point) is used. It allows devices to connect wirelessly to the LAN.

A router is essential for LANs to connect to the internet. It directs data between the LAN and the internet.

Switches are used to create a wired network by connecting devices using copper cables (Untwisted Twisted Pair), ethernet cables or high-speed fibre optical cables.

Every device on the LAN is identified by an IP address, which allows them to send and receive data correctly.
