📚 What is HTTP?
HTTP stands for Hypertext Transfer Protocol. It's the foundation of data communication on the web. Think of it as a way for your browser to ask a website for information and for the website to respond. But, it sends data in plain text, like writing a postcard that anyone can read!

🛡️ What is HTTPS?
HTTPS stands for Hypertext Transfer Protocol Secure. It's the secure version of HTTP. The 'S' means that the communication between your browser and the website is encrypted. This is like sending a secret message in a locked box – only the sender and receiver can read it!
