Lesson 259 of 300
Understand the Internet as a global network of interconnected networks that exchange packets using shared technical protocols.
Help the child understand that the Internet is a global network of many independently operated networks. Devices communicate through agreed protocols, addresses, routers, cables, radio links, satellites, servers, and data centres.
"The Internet is a global network of many connected networks. A device connects through a local network and service provider. Information is divided into packets that routers direct toward a destination. Shared protocols allow different systems to communicate. Domain names are readable names, and the Domain Name System helps locate network addresses. Servers provide data or functions to clients. The World Wide Web is one service using the Internet; it is not the entire Internet. Wi-Fi connects devices to a local network and is not the same as Internet access. The Internet connects networks so devices can exchange packets through shared protocols." DESIGN REQUIREMENTS: Use a network-of-networks model and fictional packet routing. Avoid one central Internet cloud, real websites, accounts, live links, secret chat, or implying Wi-Fi and the Internet are identical.
Pause, point, name what you notice, and connect the idea to something familiar in your child's day. Repetition, a calm voice, shared attention and dependable care matter more than finishing quickly.
