The protocol commonly used for transferring web pages on the internet is HTTP (Hypertext Transfer Protocol). It facilitates the transfer of hypertext documents, allowing users to navigate between web pages via browsers. With the evolution of the internet, HTTPS (HTTP Secure) was developed to provide an additional layer of security by encrypting the data exchanged between the server and client. This encryption protects sensitive information, including login credentials and financial data. Therefore, both HTTP and HTTPS are foundational to the function and security of the web.
