Essential Question
What must be connected for devices to exchange information?
How can data travel across many networks and still reach the correct destination?
What happens between entering a URL and receiving a web page?
Why can digital services work across devices without storing everything locally?
About this video
Follow a digital exhibition whose local files work but whose website does not load. Review network connections, packets and protocols, client–server requests, and cloud services. Separate Internet access from local connectivity, explain what DNS and HTTPS do, and connect synchronized copies with their limits and dependencies.
In this video
• Identify network devices, links, and local connectivity.
• Explain packets and the different roles of IP and TCP.
• Trace URLs, DNS, and client–server web requests.
• Compare cloud services, synchronization, backups, and offline needs.
