Which protocol is used to retrieve email from a server, as described in the material?

• A. Post Office Protocol (POP)
• B. Simple Mail Transfer Protocol (SMTP)
• C. Internet Message Access Protocol (IMAP)
• D. File Transfer Protocol (FTP)

Answer: (A)

Retrieving email from a server is about downloading messages from the mail store to your device. Post Office Protocol (POP) is designed for that purpose: a client connects to the mail server, downloads the messages to your device, and can optionally delete them from the server after download. This makes it straightforward to read mail offline and keeps a local copy.

In contrast, Internet Message Access Protocol (IMAP) is built to manage and access messages while they remain on the server, supporting synchronization across multiple devices. Simple Mail Transfer Protocol (SMTP) handles sending mail, not retrieving it. FTP is used for transferring files and isn’t related to email retrieval.
