Which of the following protocols are used for email?

Correct option is B

· SMTP (Simple Mail Transfer Protocol): Used to send emails from the client to the mail server and between mail servers.
· POP (Post Office Protocol): Used to retrieve emails from a mail server to a client application.
These protocols work together to ensure the proper transmission and reception of email messages.
Important Key Points:
1. SMTP is responsible for sending emails, while POP is used for retrieving them.
2. IMAP (Internet Message Access Protocol) is another protocol commonly used for email retrieval.
3. TELNET and FTP are unrelated to email communication.
Knowledge Booster:
· TELNET: Used for remote access to servers but not for email.
· FTP (File Transfer Protocol): Used for transferring files, not email communication.
· Modern email services often use IMAP instead of POP for better synchronization across devices.
