A Local Area Network (LAN) typically connects devices within a limited geographic area such as an office, building, or campus. AI+ Network foundational networking materials define a LAN as a high-speed network designed for local communication, enabling users to share resources such as files, printers, applications, and internet access.
LANs operate using technologies like Ethernet and Wi-Fi and are characterized by low latency, high bandwidth, and centralized administration. They differ from Metropolitan Area Networks (MANs), Wide Area Networks (WANs), and Personal Area Networks (PANs), each of which serves a different geographic scope.
LANs form the core of enterprise internal networks and are often integrated with larger networks through routers and firewalls. AI+ Network training consistently highlights LANs as the first layer of organizational network architecture.
