the telephone, email, real-time teleconference, fax, or overnight mail service. 


Each of these methods had an important role in communication today. People generally use the telephone as main means of communication today. It has the advantage of a person being able to heard another person instantly. But it also has the disadvantage of the users not being able to see each other. 


And this is where real-time teleconference comes into play. This allows you to be able to see the other person. A disadvantage of this is that people such as sex offenders can abuse. 


Fax and email are similar means of communication. They both allow typed messages to be sent. An advantage of fax, is that it allows a person to scan anything and send it. This is also true for email. A disadvantage is that fax requires a phone line. Email can be access from anything that can access internet.


Overnight Mail Service is an extremely useful service meant mainly for getting items from point A to point B as soon as possible. This advantage is slightly marred by the fact that this service is fairly expensive. Minimum prices are approximately thirty dollars.
