Suppose you have an important message to send to a friend in another city, and you can use the telephone, email, real-time teleconference, fax, or overnight mail service. Discuss the advantages and disadvantages of each. See if you can think of a situation for each of the five options in which that particular option is the most appropriate choice.

 With using a telephone: Whoever it is that you call, will be able to hear your voice, and have a complete conversation with you: making sure that no information is left out. Unfortunetly, sometimes people do not answer their phone, which can stop you from telling them the important information.

With email, any one with internet access can contact anyone (who has an email). With using emails, proximity can be an issue.

Real-time teleconference is a great solution for when you need to  be  face-to-face with somebody, but really can't be because of issues with location, and more. A set back of real-time conferencing is that it is very possible for users to have issues with connection.

With fax: Anyone can send hard copies of any information to whoever. The only thing is that sometimes, faxes do not go through and if they do the information they sent may not be clear.
