The Internet and DNS

Manual: General · Subject: Networking

Understand how the internet works as a network of networks and how DNS helps you use names instead of numbers.

From networks to the internet

The internet

The internet is a global system made of many connected networks. It allows devices and services all over the world to communicate.

What DNS does

DNS stands for Domain Name System. It translates human-friendly names like websites into IP addresses that computers use to find each other.

ℹ️

Why DNS matters

Without DNS, people would need to remember numbers for every website instead of easy names.

What happens when you visit a website

  1. 1

    Step 1: You type a website name into your browser.

  2. 2

    Step 2: DNS finds the matching IP address.

  3. 3

    Step 3: Your device sends network requests to that address.

  4. 4

    Step 4: The server sends back the web page data.
