The prefix 'http' signifies Hypertext Transfer Protocol, which is the foundation of any data exchange on the Web. When you access a secure website, the prefix changes to 'https,' where the 's' stands for 'secure.' This indicates that the website is using a secure protocol called HTTP Secure or Hypertext Transfer Protocol Secure, which adds a layer of security by encrypting the data exchanged between the user's browser and the website through a protocol known as SSL/TLS (Secure Sockets Layer / Transport Layer Security).

This shift to 'https' not only helps protect sensitive information, such as passwords and credit card numbers, but also assures users that they are communicating with the intended website and not an impostor. In contrast, the other prefixes mentioned have different functions; 'ftp' is used for File Transfer Protocol, which is not related to web browsing, while 'htm' does not represent a protocol but rather a file extension for HTML documents. Therefore, it is essential to recognize that the transition from 'http' to 'https' signifies a commitment to securing user data and privacy on the Internet.
