Explanation:
Detailed explanation-1: -HTTP and SMTP use TCP(Transmission Control Protocol). HTTP uses TCP because the files, images, and web pages that we receive from the remote host must not be dropped on the way and must be delivered in the order to the HTTP client. TCP, port 25 is used by SMTP.
