IM can be used if the people involved in the conversation are all online at one time. Instant messaging is just that, typing usually short messages to each other and instantly sending them in a 'chat' window. Some popular programs for this include Windows Live Messenger, and even FaceBook chat.
Electronic mail! Email has the same principle as IM, sending messages to each other but the people involved do not need to online at the same time. Messages are displayed in an inbox for the user to view and email is considered to be more formal as it is used more for business related topics also.
