Final answer:
The difference between POP3 and IMAP lies in the protocol they use for email communication. POP3 is used to download emails to the local storage, while IMAP allows accessing and managing emails directly on the mail server.
Step-by-step explanation:
The difference between POP3 and IMAP lies in the protocol they use for email communication.
POP3 (Post Office Protocol version 3) allows users to download emails from a mail server to their device's local storage. Once downloaded, the emails are typically removed from the server.
IMAP (Internet Message Access Protocol), on the other hand, allows users to access and manage their emails directly on the mail server, without downloading them. This allows for synchronization across multiple devices and enables users to view the same emails from different devices.
