Email, Fax, IM, letters. Can you pick the one that is not like the others?I will help you letters. These forms of data transfer can fall into two categories communication and information. There is a distinction between these things. Communication requires the other party to hear, listen and feel what the communicator is conveying. If you are informing someone then email, fax, IM are acceptable formats but they do not allow the intangible emotions, inflections and tones that talking to someone can afford. Letters are very formal and if you want to set an expectation with someone send a letter. Black ink against the white piece of paper provides permanence that electronic media cannot establish. If you want to communicate talk to someone. If you want to inform someone then use email, fax or im. If you want to establish something with someone put it in a letter. Remember the difference between communicating and informing.AH
