What defines a Local Area Network (LAN)?

A Local Area Network (LAN) is defined as a network limited to a small geographic area, typically within a single building or a campus. This definition highlights that a LAN usually covers spaces like homes, schools, or small offices, allowing multiple devices such as computers, printers, and other networked equipment to connect and communicate with each other efficiently.

The characteristics of a LAN include high data transfer rates, lower latency, and relative ease of installation and management compared to broader network types. LANs allow for shared resources, such as files and internet connections, promoting collaboration and enhancing productivity among users in close proximity.

While other choices suggest broader network configurations—like spanning multiple cities or connecting international users—these do not align with the fundamental concept of a LAN. In contrast, the mention of mobile devices in one of the options refers to a specific type of usage rather than the geographic limitations that define a LAN. Hence, the defining characteristic that accurately describes a LAN is its limitation to a small geographic area.
