Understanding LANs and WANs

This video is the second part of a series on internet structure, focusing on Local Area Networks (LANs) and Wide Area Networks (WANs). It explains the characteristics and differences between LANs, which cover small geographical areas and are typically owned by a single organization, and WANs, which cover larger areas and connect multiple LANs, often using leased infrastructure. The video concludes with a key question about the differences between LANs and WANs.
