1. The HyperText Transfer Protocol is the set of rules used to retrieve linked web pages across the web. 2. Plain HTTP carries its traffic without protection. 3.

FTP transfers files, SMTP sends mail, and TCP is a transport protocol, so none of them is the secure form of HTTP. _Source: syllabus Computer Science Class 12, Ch 10 'Computer Networks', S10.7.1 The World Wide Web (WWW)_
