Which of the following describes a local area network (LAN)?

A local area network (LAN) is specifically designed to connect computers and devices within a limited, defined geographic area, such as a home, office, or school. This setup allows for high-speed data transfer and efficient communication between connected devices. Given its limited scope, a LAN typically provides a reliable and private environment for users to share resources, such as files and printers, without the complexities associated with broader network architectures.

In contrast, a network that covers large geographical areas, connects multiple states, or is characterized as often insecure does not fit the definition of a LAN. These descriptions pertain to wide area networks (WANs) and other network types, which serve different purposes and exhibit different characteristics compared to a LAN. Understanding these distinctions is crucial for networking professionals, as they ensure the appropriate implementations and designs for various networking needs.
