What is a 'LAN'?

A 'LAN,' or Local Area Network, is defined as a network that connects computers within a limited area such as a home, school, or office building. This type of network allows devices within close proximity to communicate with each other, share resources such as files and printers, and access the internet if one device is connected to it. Typically, LANs use Ethernet or Wi-Fi for connectivity, providing high-speed communication and low latency, which is ideal for local network activities.

The focus on being limited to a specific area is what differentiates LANs from Wide Area Networks (WANs), which cover larger geographic areas and can connect multiple LANs. Understanding the characteristics of a LAN is essential for recognizing its applications in everyday environments, facilitating efficient operation for both individual users and businesses.
