HTTPS stands for Hypertext Transfer Protocol Secure. It is an extension of HTTP, which is the protocol used for transferring data over the web. The "S" in HTTPS indicates that the connection is secure, meaning that the data exchanged between your browser and the website is encrypted. This helps protect sensitive information, such as passwords and credit card numbers, from being intercepted by malicious actors. Websites that use HTTPS are often marked with a padlock icon in the address bar, signaling to users that their connection is secure. This is especially important for online transactions and any site that collects personal information. Using HTTPS helps build trust between users and websites, ensuring a safer browsing experience.
