Which protocol allows synchronization of emails across multiple devices?

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

Answer: (B)

IMAP, or Internet Message Access Protocol, is designed to let users access and synchronize their emails across multiple devices effectively. When using IMAP, emails are stored on the mail server, allowing users to view and manage their messages from different devices, such as a smartphone, tablet, or computer. Changes made on one device, like marking an email as read or moving it to a folder, are reflected on all other devices linked to the same email account. This synchronization capability makes IMAP a preferred choice for people who need consistent access to their emails on various platforms. In contrast, POP3 (Post Office Protocol version 3) downloads emails from the server to the client device and typically deletes them from the server afterward. This means that once emails are downloaded on one device, they are not accessible from another device. SMTP (Simple Mail Transfer Protocol) is used for sending emails but does not handle receiving or syncing emails, and Telnet does not relate to email protocols but is rather a protocol for text-based communication over the internet.
