2nd RADIO by ummmm in ummm

3rd computer in 19 something by ummmm it was biger than a carA pioneer in the field of telecommunications, Alexander Graham Bell was born in 1847 in Edinburgh, Scotland. He moved to Ontario, and then to the United States, settling in Boston, before beginning his career as an inventor. Throughout his life, Bell had been interested in the education of deaf people. This interest lead him to invent the microphone and, in 1876, his “electrical speech machine,” which we now call a telephone. News of his invention quickly spread throughout the country, even throughout Europe. By 1878, Bell had set up the first telephone exchange in New Haven, Connecticut. By 1884, long distance connections were made between Boston, Massachusetts and New York City.

Bell imagined great uses for his telephone, like this model from the 1920s, but would he ever have imagined telephone lines being used to transmit video images? Since his death in 1922, the telecommunication industry has undergone an amazing revolution. Today, non-hearing people are able to use a special display telephone to communicate. Fiber optics are improving the quality and speed of data transmission. Actually, your ability to access this information relies upon telecommunications technology. Bell’s “electrical speech machine” paved the way for the Information Superhighway.

Guglielmo Marchese Marconi, Italian electrical engineer and Nobel laureate, known as the inventor of the first practical radio-signaling system. He was born in Bologna and educated at the University of Bologna. As early as 1890 he became interested in wireless telegraphy, and by 1895 he had developed apparatus with which he succeeded in sending signals to a point a few kilometers away by means of a directional antenna.

After patenting his system in Great Britain, he formed (1897) Marconi’s Wireless Telegraph Company, Ltd., in London. In 1899 he established communication across the English Channel between England and France, and in 1901 he communicated signals across the Atlantic Ocean between Poldhu, in Cornwall, England, and St. John’s, in Newfoundland, Canada. His system was soon adopted by the British and Italian navies, and by 1907 had been so much improved that transatlantic wireless telegraph service was established for public use.

Marconi was awarded honors by many countries and received, jointly with the German physicist Karl Ferdinand Braun, the 1909 Nobel Prize in physics for his work in wireless telegraphy. During World War I he was in charge of the Italian wireless service and developed short-wave transmission as a means of secret communication. In the remaining years of his life he experimented with shortwaves and microwaves.

Professor John Atanasoff and graduate student Clifford Berry built the world’s first electronic-digital computer at Iowa State University between 1939 and 1942. The Atanasoff-Berry Computer represented several innovations in computing, including a binary system of arithmetic, parallel processing, regenerative memory, and a separation of memory and computing functions.

Radio, Guglielmo Marconi, 1895.

Computer, John von Neumann, 1946.

Some books and web sites still claim that the computer originated with Charles Babbage’s Analytical Engine in 1837, or with Hermann Hollerith’s card tabulator in 1889, or with any of half a dozen other automatic calculating devices up to 1945. However all of these earlier machines were different from modern computers because their method of storing the program was quite different from their method of storing the data. Von Neumann realised the enormous extra flexibility of using the same storage method for both.

The importance of the 1939-42 Atanasoff-Berry Computer is that a judge cited it as “prior art” to deny a patent on electronic computing claimed by two later inventors.

the thing is his wife was deaf

the first fully intelligible telephone call occurred on

March 6,1876, when Bell, in one room, called to his assistant, Thomas Watson, in another room.

radio was invented second

In 1896, Guglielmo Marconi was awarded a patent for radio with British Patent

thn at last computer was invented by Charles Babbage
