Understanding the Internet

The video explains how the internet works, comparing it to electricity in terms of everyday use without understanding. It describes the internet as a physical wire connecting computers, with servers having unique IP addresses. Clients connect indirectly through ISPs. Data is transmitted in packets, directed by routers using IP addresses. The video concludes with a call to explore more resources for information protection.
