Computer Networks - II — Question 41

IMAP (Internet Message Access Protocol) is a standard protocol for accessing e-mail from local server. IMAP is a client/server protocol in which e-mail is received and held for the user by internet server. IMAP holds the email until the user actually deletes it. As this requires only a small data transfer this works well even over a slow connection such as a modem. Only if the user requests to read a specific email message, then it will be downloaded from the server.
