What does LAN stand for?

LAN stands for Local Area Network. This term is widely used in networking and computer science to describe a network that connects devices within a limited geographical area, such as a home, school, or office building. Local Area Networks enable devices to communicate with each other and share resources like files, printers, and internet connections.

The other options do not accurately represent the standard terminology in networking. "Local Arena Network" and "Long Arena Network" introduce terms that do not align with known networking concepts, while "Long Area Network" is misleading as it suggests a network over a larger space, which is typically referred to as a Wide Area Network (WAN) instead. Therefore, the term Local Area Network effectively encapsulates the essence of a LAN as a confined network serving a specific area.
