Communications is an important part of our day-to-day daily lives. As people, (and others such as animals) we need to be able to interact and express ourselves among eachother in order to get something across (i.e. ideas and opions) and just to be able to do anything in this world. Up unitl this technological era, which I happened to grow up in, there have been only two common types of communication: oral and written. Now, there is a new type that emerged: electronic. So, it is practically a necessity for us.
