    WEB is port 80 standard http

    Secure Web is port 443 https

    Ftp uses 20/21, data is 20 control 21 both TCP.

    When the question is transport layer protocol, I would assume:

    TCP or UDP.

    Like DNS is both TCP and UDP, SSH is TCP only, telnet is TCP only, etc.

    Web is probably HTTP

    Secure web is probably HTTPS
