The telephone one of the best.

The telephone one of the best. The telephone is one of the most used inventions ever invented. It is used world wide connecting people from one side of the world to the other side. They send speech over long distances by using electric currents, laser light or radio waves. The telephone was invented in 1876 by a Scottish engineer called Alexander Graham Bell who lived from 1847-1922. He had been working in the United States on improving the telegraph, which used Morse code which used dotes and dashes to send the messages to other users but it was limited, but so were the early phones. By 1880, the first public telephone system were in use, although they had hardly any subscribers. Early telephones were connected by wires to a telephone exchange, where operators would connect the two wires by hand which was very hard when the invention got bigger and more people were using it. The invention of automatic switches in the 1890s allowed the exchanges to connect calls without going though an operator, where there could be problems or mistakes which all lost time. Modern telephone systems change the varying electrical signal of older phones into a digital signal made up of electrical pulses that are handled by computerized exchanges, getting rid of the old fashioned mechanical ones of lots of people playing with wires. A telephone handset works with a mouthpiece and an earpiece,

Verbal and Non - verbal Communication

Introduction Communication is the study of the transfer of meaning (Eunson, 2005, p.2). This consists of verbal communication, which is the exchange of ideas through written or spoken words and non - verbal communication, which is conveying a message through cues such as facial expressions (a smile), head movements (shaking left to right), proxemics (closeness in proximity) and eye messages (a stare). It is virtually impossible to not communicate, as further proved by the axiom - "You cannot not communicate". There can also be considerable misunderstanding due to the noise factors that obstruct easy flow of communication, which can be dismissed if the misconceptions are understood and remedied. Verbal cues can be easily controlled; where as the non - verbal cues have little or no control as they are exhibited by the speaker more or less without his or her knowledge. These are more spontaneous and the individual has less control over them, thus making it more genuine and real. Consequently, at times when the verbal cues and the non - verbal cues are contradicting, it is the general practice for the listener to perceive the message displayed by the non - verbal cue. In a face to face conversation or verbal exchange, the words take only 7% of the effectiveness of delivering the proper message, where as the tone of voice and non - verbal communication consists of 38% and 55%
