Telephones
Telephones are among the most popular and convenient devices ever invented. Since their invention， they have provided much convenience in all kinds of life. They enable a timely exchange of information， however far apart people may be from each other. Telephones help save not only time， energy， but money as well. So they are welcomed by more and more people.
Telephones have been useful in many ways. They may help you obtain information in a comparatively quick way. The timely information will place you in an advantageous position in a world of competition when it comes to decision making related to your business. Besides， if you want to make an appointment with others， you might wish to use a telephone to get it arranged beforehand， to avoid inconvenience caused by your unexpected arrival.
However， the telephone can be annoying sometimes. Just imagine you are sound asleep when you are startled awake by the telephone rings only to find it is a wrong call. Nothing is more annoying than that. You have to answer one call after another， whether it is necessary or not. Nevertheless， all these are unimportant， compared with the convenience telephones provide.
