It is not just in business that computers have affected us so profoundly;
communication has been revolutionised totally. Firstly, whereas before, people
wrote letters, which would often take weeks to reach their destinations, or
speak on the phone, which was terribly expensive, now they e-mail. For
instance, instead of waiting weeks for a letter now, we can read it instantly,
seconds after it’s been written. Secondly, many people use computers to
communicate with people all around the world using chat rooms and chat
programs, this was impossible before the computer became widespread. As a
result, now people who live thousands of kilometres away from each other can
communicate as much as they want and whenever they want using e-mail
and/or chat rooms.
