Computer Network Basics Questions Medium
A Wide Area Network (WAN) is a type of computer network that spans a large geographical area, typically connecting multiple local area networks (LANs) or other WANs together. It allows for the transmission of data, voice, and video across long distances, often using public or private telecommunications infrastructure. WANs are commonly used by organizations to connect their branch offices, data centers, and remote locations, enabling communication and resource sharing between different sites. Unlike LANs, which are confined to a smaller area like a building or campus, WANs can cover vast distances, such as connecting offices in different cities or even countries. They utilize various technologies, including leased lines, satellite links, and internet connections, to establish connectivity between different network nodes.
