Transcript of Communication Technology; The Past, Present and Future

Communication Technology; The Past, Present and Future The Introduction The Conclusion I am writing about communication technology in the past, present and future and it's uses.

In the past, the type of communication technology devices has evolved smoke signals, carrier pigeons to letters and telegrams. Nowadays, there are more efficient way to communicate such as through e-mails, fax machines, mobile phones and the list goes on. From my point of view, the differences of communication technology in the past and today are that it is more advanced and it involves face-to-face communication. In the past a traditional way of communicating has always been to write letters to other people as a means of communication. The Phoenician alphabet, the early postal system in China, the use of homing pigeons in Ancient Greece and there are lots of types of early communication as well as telegrams and suchlike.

Pen, paper, and postal (snail) mail was the usual way to send letters and correspondences. Mail would take 3-7 days to arrive to its destination. Express and overnight mail was an expensive option (continues to be). Fax was often another way to was also expensive and not always time/user friendly. Communication Technology; The Past Communication Technology; The Present Be able to send email with your own thoughts or brainwaves where ever you are. Like with paper checks, postal mail may become a thing of the past. Physical package delivery is likely to continue until the teleportation of merchandise is possible.

In the future we shall probably have micro-chips installed in our brain making it easy for us to communicate (and call) each other and search the web quickly finding out what you need. Communication Technology; The Future Communication technology will have a great impact on our life in the future, twice as much as it does nowadays. In the not-so-distant future we will be able to converse with people who are halfway across the world as if they were right next to you. Timeline from before 3500 BC - 1942
