What does LAN stand for?

The term LAN stands for Local Area Network. This refers to a network that connects computers and devices in a limited geographic area, such as in a home, office, or campus. LANs are characterized by their high data transfer rates and low latency, making them ideal for sharing resources such as files, printers, and internet connections among computers that are physically close to each other. The architecture of a LAN can vary, but most commonly it involves cabling or Wi-Fi technology to facilitate communication between devices.

In contrast, the other options refer to terms that are not standard or recognized terms in networking. "Large Access Node" does not accurately represent a type of networking setup; rather, it suggests a component without context on its functionality. "Lightweight Application Network" is not a commonly used term within networking contexts, and does not relate directly to local area connectivity. "Locked Access Network" similarly lacks relevance, as it is not a recognized classification within networking terminology, which tends to focus on the geography and access methodology of networks. By understanding the definition and application of a Local Area Network, one can better grasp the overall foundation of networking concepts and connectivity solutions.
