What is a 'Local Area Network' (LAN)?

A 'Local Area Network' (LAN) is defined as a system confined to a specific area for device communication. This means that a LAN connects computers and devices within a limited geographic region, such as a home, office building, or campus. The primary characteristics of a LAN include high data transfer rates and relatively low latency, allowing devices within the network to communicate with each other efficiently.

LANs are typically used to share resources, such as files and printers, and can facilitate communication between devices without the need for internet access. The focus on a specific area distinguishes LANs from other types of networks that cover broader geographic scopes. Understanding the LAN's role and limitations can help in network design and implementation, emphasizing the importance of localized connectivity in various settings.
