Telegraph History 1800 – 2020 Pdf Ebook – Full Version

Description

No. 2 Telegraph 1800-2020 is part of the Telecommunication Family is the exchange of signs, signals, messages, words, writings, images and sounds or information of any subject by wire, radio, optical or other electromagnetic systems. Telecommunication occurs when the exchange of information between communication participants includes the use of technology. It is transmitted through a transmission medium, such as over physical media, for example, over electrical cable, or via electromagnetic radiation through space such as radio or light. Such transmission paths are often divided into communication channels which afford the advantages of multiplexing. The Latin term communication is considered the social process of information exchange.

Early means of communicating over a distance included visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags and optical heliographs. Other examples of pre-modern long-distance communication included audio messages such as coded drumbeats, lung-blown horns, and loud whistles. 20th- and 21st-century technologies for long-distance communication usually involve the histories of 1 Electrical and Electromagnetic Technologies, such as this chapter 2 The Telegraph 1800-2020, 3 Telephone History, 4 Radio & Television, 5 Computer Laptop & iPads, 6 WWW, Optical Fiber and Communications Satellites.

Telecommunication Family 1 to 6, the next chapter in this series No. 3 Telephone History. Shows early examples of experimental Ideas, Invention & Design, using different methods of experimental and practical switching, to recording sound. In 1860 the Reis Transmitter, (all developed before A.G. Bell invented his telephone). Alexander Graham Bell was awarded the first U.S. patent for the invention of the telephone in 1876. Elisha Gray, 1876, designed a telephone using a water microphone in Highland Park, Illinois. Tivadar Puskás proposed the telephone switchboard exchange in 1876. A telephone (derived from the Greek “voice”, together meaning “distant voice”), or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user.

 

Another revolution is 4 Radio wireless plus Television communication began in the first decade of the 20th century with the pioneering developments in radio, see next chapter 4, communications by Guglielmo Marconi, who won the Nobel Prize in Physics in 1909, and other notable pioneering inventors and developers in the field of electrical and electronic telecommunications. Edwin Armstrong and Lee de Forest (inventors of radio), as well as Vladimir K. Zworykin, John Logie Baird, Charles Francis Jenkins and Philo Farnsworth (some of the inventors of television).

(5 Inventors of Computers) Charles Babbage, Paul Allen and Bill Gates, Steve Jobs and Steve Wozniak start Apple Computers. (6 Inventors the WWW) English scientist Tim Berners-Lee invented the World Wide Web in 1989. 1952, UK based physicist Narinder Singh Kapany invented the first actual fibre optical cable. Satellite communications play a vital role in the global telecommunications system.

All these technologies require each invention to progress to the next evolutionary stage and stand the test of time.
