POP3 downloads emails to one device and deletes them from the server, while IMAP syncs emails across devices and keeps them on the server.
Explanation
The primary difference between these two email retrieval protocols lies in how they manage message storage and synchronization.
POP3 (Post Office Protocol version 3): Typically downloads emails from the server to the client device and then deletes the copy from the server, meaning the email is only stored locally on that one specific device.
IMAP (Internet Message Access Protocol): Keeps emails stored on the server, allowing them to be synchronized and accessed across multiple devices simultaneously.
The functional relationship can be summarized as:
POP3⟹Local Storage (Delete from Server)
IMAP⟹Server Storage (Sync across devices)
Therefore, the correct option is (a).
