The invention of telephone
The
telephone is one of the greatest inventions in history. Early telephones were nothing like the ones we have today . Telephone is the Greek word for “far sound .”
Before the invention of telephone, people used fax, postal letters and birds to communicate.
Alexander Graham Bell was an eminent scientist, inventor , engineer and
innovator who intented the first telephone. His mother and his wife were both deaf and that was the main reason which caused his interest to hearing devices . Bell invented the telephone by accident when he
was trying to invent a device that could send more than one telegram at the same time.
His
research on hearing and speech further led him to experiment with
hearing devices which eventually culminated with the telephone in
1876.

The invention of the telephone The invention of the telephone is the culmination of work done by many individuals. The presumption for the development of the telephone goes back to the year 1833 were Carl Friedrich Gauss and Wilhelm Eduard Weber invented the electric transmission of signals in Göttingen which set the fundamental basis for the technology. This invention is recognized to be the first electromagnetic telegraph of the world. (The development of the modern telephone involved an array of lawsuits founded upon the patent claims of several individuals.) Some of the inventors who gave their contribution for inventing the telephone are: Innocenzo Manzetti - Innocenzo Manzetti considered the idea of a telephone as early as 1844, and may have made one in 1864. He is considered by many Italians as the inventor of the telephone. Johann Philipp Reis - In 1860 Reis was the first who produced a functioning electromagnetic
marker at the doorstep, marking it as Alexander Graham Bell's birthplace. He had two brothers: Melville James Bell (18451870) and Edward Charles Bell (1848 1867). Both of his brothers died of tuberculosis. His father was Professor Alexander Melville Bell, and his mother was Eliza Grace (née Symonds). Alexander Graham Bell was an eminent scientist, inventor, engineer and innovator who is credited with inventing the first practical telephone. Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils and aeronautics. In 1888, Alexander Graham Bell became one of the founding members of the National Geographic Society. He began teaching at a deaf school in Boston, and lodged with Thomas Saunders, and met Gardiner Hubbard, whose daughter, Mabel, had been deaf since the age of five. Quite unable

Unfortunately this technology has been relegated in a niche market due to several factors such as proprietary standards, high price tag, limited integration with existing telephony environments. However in the last couple of years the situation changed dramatically since some open source tools such as asterisk as well as low-cost VoIP telephone adapters and services become available. In fact, today it is quite common for
or mass audiences. The most important are probably Television, Radio, the Press and Internet. The English-speaking peoples have always allowed more freedom of speech and of the press than most other countries. This gave them an advantage from the start in communications. The ground work for mass communications in the 20th century was laid in the 19th century by two inventions which allowed people to communicate by wire. These were the electric telegraph and the telephone. The telegraph was invented in Britain in 1837. They were being used in the Civil war. It allowed messages to be sent electrically over telegraph wires. This was much faster and more reliable than sending messages by horse messenger. the telephone was invented In 1876 by Alexander Graham Bell. The first radio broadcasts were transmitted in the USA in 1916. Radio is generally the first of the news media to report a local story.
Mass Media Mass media is a term used to describe those means of communication which can reach large or mass audiences. The most important are probably Television, Radio, the Press and the Internet. Britain and America invented a lot of the technology used by the various modern communications media. In 1829, the typewriter was invented in America. In 1837, the telegraph was invented in Britain. In 18 76, Alexander Graham Bell invented the telephone in America. This made it possible to talk to people thousands of miles away. The telephone is a telecommunications device, which is used to transmit and receive sound. It's one of the most common household appliances in the world today. The English-speaking peoples have always allowed more freedom of speech and of the press than most other countries. This gave them an advantage from the start in communications. Book-publishing grew rapidly in early modern England and America. So did
information will need careful planning and organizing. · Correct Grammar and Spelling Train yourself to check for major grammatical errors, words which are commonly misspelt and sentences which are incomplete. · Suitable Style and Tone The style and tone must match the message and its reader. You cannot, for example, write a memo to a colleague in the same style and tone as you might use when speaking on the telephone to a friend. · Logically Connected Ideas Finally, your ideas must be suitably connected so that the reader can identify related ideas while reading through and gradually understanding the message. Text 1 and Text 2 below clearly show these five aspects of writing in the business world. Evaluation Exercise 1 In the Field Services Department of the Melbourne Construction Company (MCC), a problem
The Use of the Telephone in Relation to Customer Service **Telephone skills are the most important aspect of being successful in a call center job. When you work on the phone all day as a customer service representative, the telephone is the one and only tool that will make or break your success. The phone is probably the most used tool in modern business. **Answering the phone professionally The rules for answering a telephone are simple but they need to be continually reviewed and practised. Following are the most basic ones, which should always be employed. 1. Use the four answering courtesies: · Greet the caller · State your organisation (or department) · Introduce yourself · Offer your help "Good afternoon, Accounts, Andrew Batt speaking. How may I help?" 2. Show enthusiasm when you answer. Help make the caller feel welcome
SCIENCE AND TECHNOLOGY A century ago communication across any distance was dependent upon the telegraph or letters. No jets crossed the ocean, no television pictures enabled us instantly to see events in any part of the world, there were no worldwide telephone networks and no computers. It is just a short lifetime since humanity first travelled into space and discovered how fragile our planet looks. FROM FIREWORKS TO THE MOON At first glance you might think that there couldn't possibly be anything common between a 13 th century festival in China and the Apollo 11 moon landing in 1969. However, there is a link and that is that they both relied on the use of rockets.
