The Internet And The World Wide Web

Muhtasari

"The internet" and "the web" get used as if they were the same thing, but they are not: one is the physical and addressing structure connecting billions of devices, the other is a service that runs on top of it, made of linked pages and the protocols that fetch them. Confusing the two is one of the most common mistakes students make in this topic.

This lesson separates the internet's structure, IP addressing and the domain name service, from the world wide web's own components: web servers, URLs, ISPs, HTTP, HTTPS and HTML. You will also compare IPv4 and IPv6 addressing, and see how a modem, router, switch and wireless access point combine to get a home or office onto the internet in the first place.

Malengo

  1. Understand what is meant by the internet and how the internet is structured (IP addressing, domain name service (DNS))
  2. Understand what is meant by the world wide web (WWW) and components of the WWW (web server URLs, ISP, HTTP, HTTPS, HTML)
  3. Understand the need for IP addressing standards and the formats of IPv4 and IPv6
  4. Understand the role of components used to access the internet (modem, router, switch, wireless access point (WAP)) and how these are combined

Maelezo ya Somo

The internet is a vast, global network of interconnected networks, the physical and logical structure that lets any connected device exchange data with any other. The world wide web (WWW) is one service that runs on top of that structure: a system of linked, formatted pages, accessed using specific protocols and displayed by a browser. Email, file transfer and online gaming also run over the internet but are not part of the web. Every website requires the internet to exist; the internet existed, and is used for other things, without needing the web.
