Communications

Networks have allowed easy communication from one person to another. Electronic mail (e-mail) has revolutionised the ease and frequency of communication within an organisation as well as nationally and internationally. It is now very convenient to drop a quick note to a colleague (anywhere in the world) to clarify a point or get an opinion without leaving your computer.

Because of its nature, e-mails can be sent at any time of the day and to any address in the world. If the intended recipient lives in another time zone, such as the other side of the world, one party does not have to be woken in the middle of the night unlike with a telephone call, and unlike faxes, a machine does not have to be always on and loaded with paper at the recipient’s address. This means that communication is very easy but also that it is tempting to send many more e-mails than may be necessary.
