HTML

HTTP (Hypertext Transfer Protocol): This is the protocol your web browser uses to request and receive webpages from servers. When you type a URL into your browser, it sends an HTTP request to the server, which then sends back the webpage as a response. HTTP is a "stateless" protocol, meaning each request/response pair is independent.

HTTPS (HTTP Secure): HTTPS is HTTP with an extra layer of security. It encrypts the data exchanged between your browser and the server using SSL/TLS. This helps protect sensitive information (like passwords or credit card numbers) from being intercepted by third parties.
