Which of the following is a non-HTTP scheme?

Correct option is B

FTP (File Transfer Protocol) is a non-HTTP scheme used for transferring files between a client and server. Unlike HTTP and HTTPS, which are used for web communication, FTP is specifically designed for file uploads and downloads.
Important Key Points:
1. FTP: Operates over ports 20 (data transfer) and 21 (control connection). It is a protocol for file transfer and does not use HTTP.
2. HTTP/HTTPS: These are web-based protocols used for retrieving and transmitting hypertext data over the internet.
3. SFTP: Secure File Transfer Protocol is also non-HTTP but is not a primary answer here compared to FTP.
Knowledge Booster:
· HTTP (Hypertext Transfer Protocol): Used for transferring hypertext documents on the web.
· HTTPS (Hypertext Transfer Protocol Secure): A secure version of HTTP using encryption protocols like SSL/TLS.
· FTP (File Transfer Protocol): Focused on file transfer, lacking web-based hypertext capabilities.
· SFTP (Secure File Transfer Protocol): Provides secure file transfer over SSH, unrelated to HTTP.
