How would you define a local area network (LAN)?

A local area network (LAN) is defined as a network that connects computers and devices within a limited geographical area, such as a home, office, or building. This network allows for the sharing of resources, like files and printers, and provides high-speed connectivity among connected devices. The focus on the "local area" emphasizes that it typically covers a small geographical space, making it distinct from wide area networks (WANs) that can span large distances between different cities or countries.

In this context, LANs facilitate communication and resource sharing efficiently and securely, with low latency and high bandwidth, which is ideal for environments where users need to collaborate closely. The importance of understanding the LAN concept lies in its foundational role in networking, representing the starting point for more complex networking structures and technologies.
