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

The main function of a local area network (LAN) is to facilitate interconnection of devices within a limited area, such as a home, office, or school. LANs are designed to enable computers and other devices to communicate and share resources like files, printers, and internet connections efficiently. They are typically characterized by their high-speed connections and relatively short distances between devices, which distinguishes them from other types of networks that cover larger geographical areas.

In a LAN, devices are often connected using Ethernet cables or Wi-Fi technology, allowing for easy access and communication among users in the same physical location. This localized interconnectivity allows for effective collaboration and resource sharing, making it an ideal solution for environments where users need to work together closely.
