What Happens When You Type a URL

1One page, every term
Typing one URL
Play it whole, or step through and match each word to what happens. Drag sideways to turn.
2The pairs students mix up
| Pair | The difference in one line |
|---|---|
| Internet vs WWW | The Internet is the network of computers; the web is the linked pages that travel over it |
| Web page vs website | A web page is one document; a website is many related pages under one domain name |
| Domain name vs URL | A domain name names a server (ncert.nic.in); a URL is a page's full address, protocol to file |
| Web browser vs web server | The browser requests and displays pages; the server stores and delivers them |
| Web server vs web hosting | The server is the computer that keeps the site; hosting is the service of keeping it there online |
| HTML vs XML | HTML displays data with predefined tags; XML stores and carries data in your own tags |
| HTTP vs HTTPS | HTTPS encrypts what travels between browser and server; HTTP does not |
