POP - GCSE Computer Science Definition

POP (POP3), which stands for Post Office Protocol version 3, is a method used for retrieving emails from a mail server to your computer or device. When you use an email application that supports POP3, it connects to your email server, downloads your messages, and then stores them on your device so you can read them even if you are offline. One important thing to know about POP3 is that it typically removes the emails from the server after they are downloaded, which means you won't be able to see those emails from another device. This protocol is simple and useful if you want to keep your emails saved on one device.
