Question

Which is the standard protocol for sending emails across the Internet ?

• A. Hyper Text Transfer Protocols (HTTP)
• B. Post Office Protocol (POP)
• C. Simple Mail Transfer Protocol (SMTP)
• D. Internet Message Access Protocol (IMAP)

Answer 1

Answer:

C. Simple Mail Transfer Protocol (SMTP)

• The TCP/IP suite of protocols provides a flexible email system that's built on basic protocols, including Simple Mail Transfer Protocol (SMTP) for sending mail, and Post Office Protocol 3 (POP3) for receiving mail.
• Alternatively, the Internet Message Access Protocol (IMAP) can be used for receiving mail, as it enables access to email from any device, anywhere.
• With POP3, the email message is downloaded from the email service and stored on the requesting device and can only be accessed using the same device.
