Learn in the textbookMail, File, and Operations Protocols
DefinitionIMAP is a receiving protocol for reading and organizing mail from a device while the mail stays on the server.
ExplanationThe widely used version is IMAP4. The device connects to the server mailbox each time mail is read, and works with the mail without copying all of it locally.
AnalogyIt is like leaving your photos in your own online album and opening it from whichever device you have at hand to view and sort them.
Memory hookFocus on "Access" in Internet Message Access Protocol. You do not take the mail home; you go and access it where it sits on the server.
