IMAP,DHCP,SSH are all application layer protocol

The correct answer is SMTP

Key Points

The File Transfer Protocol (FTP)

It is a standard network protocol used for the transfer of computer files between a client and a server on a computer network.

Simple Mail Transfer Protocol (SMTP)

SMTP stands for Simple Mail Transfer Protocol.

SMTP is used when an email is delivered from an email client, such as Outlook Express, to an email server or when an email is delivered from one email server to another.

SMTP uses port 25.

Remote Procedure Call (RPC)

RPC stands for Remote Procedure Call. It is a protocol that one program can use to request a service from a program located in another computer on a network without having to understand the network's details. In other words, it's a way for procedures to be executed on other systems on a network.

Therefore SMTP protocol is used for transforming electronic mail messages from one machine to another

The correct answer is SMTP.

Key Points

• Simple Mail Transfer Protocol:
  • An SMTP (Simple Mail Transfer Protocol) server is an application that's primary purpose is to send, receive, and/or relay outgoing mail between email senders and receivers.
  • SMTP is part of the application layer of the TCP/IP protocol. Using a process called “store and forward,” SMTP moves your email on and across networks. It works closely with something called the Mail Transfer Agent (MTA) to send your communication to the right computer and email inbox.

Important Points

• IMAP (Internet Message Access Protocol) is an email protocol that deals with managing and retrieving email messages from the receiving server.
• Since IMAP deals with message retrieval, you will not be able to use the IMAP protocol to send emails. Instead, IMAP will be used for receiving messages.
• POP stands for Post Office Protocol. And the number three stands for “version 3,” which is the latest version and the most widely used — hence the term “POP3.”

Correct Option is 5).

To send a mail, SMTP is used two times: one between the sender and sender’s mail server and the other between the two mail servers. 

SMTP Commands : 

• These commands are sent from the client to the server.
• Each command consists of a keyword followed by zero or more arguments.
• It means there are also some keywords that do not contain any argument.

The format of the command is as follows : 

 Keywords : argument(s) 

The basic SMTP works well, but it is limited in several respects:

→ It does not include authentication. This means that the FROM command give any sender address that it wants. This is quite useful for sending spam.

→ Another limitation is that SMTP transfers ASCII messages, not binary data. Therefore, the base64 MIME content transfer encoding was needed. However, with that encoding the mail transmission uses bandwidth inefficiently, which is an issue for large messages.

→ A third limitation is that SMTP sends messages in the clear. It has no encryption to provide a measure of privacy against prying eyes.

Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications.
