Which statement about IMAP4 compared with POP3 is true?

• A. IMAP4 downloads messages to the client and deletes them from the server.
• B. IMAP4 stores messages on the server and allows access from multiple devices.
• C. POP3 is better for accessing mail from multiple devices.
• D. Both IMAP4 and POP3 operate identically.

Answer: (B)

IMAP4 is designed to keep your mail stored on the server and to synchronize access across multiple devices. When you read, move, or flag messages with IMAP, those actions are reflected on the server and become visible from any device that connects to the same mailbox. This is why the statement that IMAP stores messages on the server and allows access from multiple devices is true. In contrast, POP3 is built around downloading mail to a single device and often removing it from the server after download, which makes accessing the same messages from multiple devices less seamless. That’s why the other options don’t fit: IMAP doesn’t typically download and delete on the server by default; POP3 isn’t the better choice for multi-device access; and the two protocols do not operate identically.
