A Local Area Network (LAN) is a collection of interconnected devices, such as computers, printers, and servers, that are confined to a small geographical area. This area is typically a single building, an office, a home, or a university campus.
Key characteristics:
    
 Limited Area: Operates within a restricted physical space.
    
 High Speed: Generally offers very high data transfer rates.
    
 Private Ownership: The network is usually privately owned and managed by the organization it serves.
Technologies like Ethernet and Wi-Fi are commonly used to build LANs.
