The POP protocol, by default, is set to download all the messages from the e-mail server onto your computer. This means that all the actions performed on the messages such as reading, moving, or deleting will be performed on one's computer. Because everything is kept on the user’s computer, the user will not be able to reopen messages from any location other than the computer where the messages have been downloaded. Whereas the IMAP protocol, by default, allows the user to keep all messages on the server. It constantly synchronizes the e-mail program with the server and displays what messages are currently present. All the actions performed on the messages will be done directly on the server which means that the email account can be accessed from any computer that can access the server.
