POP (Post Office Protocol) is used to retrieve emails from a mail server. It downloads emails to the client device and typically removes them from the server, allowing offline access.
Key points
Definition:POP (Post Office Protocol): downloads emails from a mail server to the client and typically REMOVES them from the server.
Emails can be read offline after downloading.
Once downloaded and removed from the server, emails are only available on the device they were downloaded to.
Exam Tip:POP DOWNLOADS and REMOVES from server. IMAP KEEPS emails on the server. This is the key difference.
Common Mistake:Confusing POP with IMAP. POP = download and delete from server. IMAP = keep on server and sync across devices.
