Telephone: The Technology of the Voice1. Introduction:The invention of telephone is the most wonderful innovation considered in the world. We often consider our society saturated with technologies of various types. The telephone is classified among information and communication technologies. Today it is considered one of the main sources of communication. It precisely shapes and works the challenges of interaction between two separate parties: long distances are overcome instantly, and any phone in the world can connect to different places via networks. In this material I would like to focus on the remarkable, persistent and essential contribution of the telephone and its impact on modern social, political, economic and engineering practices.2. What is the telephone? The telephone, often called a telephone, is a telecommunications device designed to transmit and receive the human voice simultaneously (Colins 1977). This device encourages people separated by large distances to communicate without losing contact with their business and some social responsibility.

Wilson, demonstrated the first working telephone.

ConclusionSo far the invention of the telephone has provided a means of development. It is a key contributor to engineering and technological progress. The telephone has played a vital role in the development of engineering, medicine and social welfare. Today, people separated over a long distance under network coverage can still be in contact with the help of this device. However, the phone has also been reported to be used by young people for illegal purposes such as bullying and distribution of child pornography. It has been reported that prolonged contact with cell phone could cause brain tumors, etc. due to the emission of radiation from it.
