How the Internet Works

Every time you open a website, something amazing happens in milliseconds.

The journey of a webpage:

1. You type a URL (like aiclubafrica.ng) in your browser
2. Your browser asks a DNS server: "What is the IP address for this domain?"
3. DNS replies with the server IP address
4. Your browser connects to that server and requests the page
5. The server sends back HTML, CSS and JavaScript files
6. Your browser reads those files and displays the page

Key terms:

URL — the web address (Uniform Resource Locator)
DNS — Domain Name System, like a phone book for the internet
IP Address — unique number identifying every device online
Server — a powerful computer that stores and serves websites
Browser — software that reads and displays web pages (Chrome, Firefox)

Nigerian internet facts:

Nigeria has over 100 million internet users. Lagos alone generates more web traffic than most African countries. Every Nigerian business needs a website — and someone needs to build them.
