All the protocols that end with S, (SMTPS,POP3S,ESMTPS,POP3S and HTTPS) use Security Socket Layer (SSL) encryption or Transport Layer Security (TLS) encryption to protect the contents of emails.
Core FTP, or File Transfer Protocol, was developed as a Windows client to enable the transfer and management of data across the internet. It also encrypts the data for security and to protect from hacking.
The protocol commonly used to view data over a network is the Hypertext Transfer Protocol (HTTP). It facilitates the transfer of hypertext documents, enabling web browsers to retrieve and display web pages from servers. For secure communication, HTTPS (HTTP Secure) is used, which encrypts data exchanged between the client and server. Other protocols, like FTP (File Transfer Protocol), can also be used for transferring files over a network.
To upload files to a web server, the most commonly used protocol is FTP (File Transfer Protocol), which allows for efficient file transfer between a client and a server. Alternatively, SFTP (SSH File Transfer Protocol) is a secure version of FTP that encrypts the data during transfer. For web applications, HTTP/HTTPS can also be used for file uploads through forms, typically leveraging the POST method. Each protocol has its own advantages depending on the specific requirements of security and ease of use.

Telnet does not encrypt anything; that is why it is too insecure to use as a network protocol.
Hyper Text Transfer Protocol Secure is also known as HTTPS. It is a secure data transfer protocol.
A set rule for transfer data
SFTP stand for "Secure File Transfer Protocol" or Secure FTP. It is a program that uses SSH to transfer files. Unlike standard FTP, it encrypts both commands and data, preventing passwords and sensitive information from being transmitted in the clear over the network.
A set of rules used for transferring data over the Internet is called a "protocol".Hypertext transfer protocol, HTTP.
A reliable data transfer is one that is stable . For a reliable data transfer a connection oriented protocol is used. A connection oriented protocol is one that receives acknowledgement from the receiver before sending the further data.

The protocol part of a web address, commonly referred to as the scheme, indicates the method used for data transmission between the client and the server. It typically appears at the beginning of a URL, such as "http://" or "https://". The "http" stands for Hypertext Transfer Protocol, while "https" indicates a secure version of the protocol that encrypts data for safer communication. Other protocols like "ftp://" for file transfers can also be used in specific contexts.
