What is created when two or more LANs are connected using a public network?

The concept of connecting two or more Local Area Networks (LANs) using a public network typically results in the creation of a Wide Area Network (WAN). WANs are designed to cover larger geographic areas compared to MANs (Metropolitan Area Networks) and LANs (Local Area Networks), making them suitable for linking networks that are far apart, such as networks located in different cities or countries.

When LANs are interconnected through a public network, like the Internet, it enables communication and resource sharing across long distances. WANs use various technologies, including leased lines, satellite links, and even the Internet itself, to facilitate this connectivity. By leveraging public networks, organizations can effectively build a broader network infrastructure, allowing for centralized data access and collaboration across dispersed locations.

In contrast, the other options refer to different network types: LANs serve localized connections, MANs are tailored for metropolitan areas, and VPNs (Virtual Private Networks) focus on secure, encrypted connections over public networks rather than specifically addressing the interconnection of multiple LANs. Thus, the correct answer accurately reflects the definition and scope of WANs in the context of connecting multiple LANs through public networks.
