Which protocol typically keeps mail on the server and allows access from multiple devices?

• A. IMAP
• B. POP3
• C. SMTP
• D. FTP

Answer: (A)

The main idea is how email is retrieved and stored across devices. IMAP keeps mail on the server and synchronizes actions (read, unread, deleted, moved to folders) across all devices that access the account. This means you can check your inbox from your phone, tablet, and computer, and see the same messages with the same status on every device. POP3, on the other hand, generally downloads messages to a single device and may remove them from the server, making it harder to access the same emails from multiple devices or keep them in sync. SMTP is used for sending mail, not for retrieving or storing messages, so it doesn’t address access across devices. FTP is a file-transfer protocol unrelated to email retrieval or synchronization.
