Match each protocol (Column A) with its primary function or description (Column B).

S.N	Column A	S.N	Column B
a.	SMTP	i.	Protocol for sending emails between servers
b.	IMAP	ii.	Protocol for retrieving and synchronizing emails on the server
c.	POP3	iii.	Protocol for downloading emails (often removing them from the server)
d.	MIME	iv.	Standard for formatting multimedia email messages

Which option correctly matches the items?

Correct option is C

The correct matches for the protocols are as follows:
· SMTP (a) is the protocol used for sending emails between servers, hence it matches with i.
· IMAP (b) is used for retrieving and synchronizing emails from the server, so it matches with ii.
· POP3 (c) is used for downloading emails from the server, often removing them, so it matches with iii.
· MIME (d) is a standard for formatting multimedia email messages, so it matches with iv.
Important Key Points:
1. SMTP (Simple Mail Transfer Protocol): SMTP is responsible for sending emails between mail servers. It handles outgoing email delivery.
2. IMAP (Internet Message Access Protocol): IMAP allows users to access and manage their emails on the server, keeping emails synchronized across devices.
3. POP3 (Post Office Protocol 3): POP3 downloads emails from the server to a local device, often removing the email from the server in the process.
4. MIME (Multipurpose Internet Mail Extensions): MIME is a standard used to encode multimedia content, such as images and attachments, into email messages.
