HTTP stands for Hypertext Transfer Protocol and is a protocol for transmitting data on the internet. It is the foundation of data communication on the World Wide Web. When you enter a website's address into your web browser, your computer sends a request to the server hosting the website, and the server sends back the website's content in response.
HTTPS stands for HTTP Secure and is a variant of HTTP that adds an extra layer of security by encrypting the data being transferred between your computer and the server. When you access a website using HTTPS, the connection between your computer and the server is secured using a technology called SSL/TLS (Secure Sockets Layer/Transport Layer Security). This helps to prevent third parties from intercepting or tampering with the data being transmitted.
In short, HTTPS is a more secure version of HTTP, and it is commonly used for online transactions and other sensitive activities that require a higher level of security.
