who invented tv and computer
Answers
Answer:
TV;
Philo Taylor Farnsworth (invented but not built until 1927 and proved via a back-dated 1922 patent ruling).
John Logie Baird (independently built and via a different method in 1925).
TV’s today use the system of Farnsworth not Baird (or did until the flatscreen era etc anyway).
Radio;
Nikola Tesla (devised by Guglielmo Marconi via a machine that Tesla had built for another purpose)
Marconi (built)
Tesla wanted his machine to transmit electrical power (which ultimately it couldn’t do) not merely transmit electrical signals (which it could easily do). So he was uninterested when Marconi suggested that alternative for it. So Marconi went ahead without him and was credited with being the `inventor’ - though less so these days given that Tesla’s role is better known now.
Computer;
The abacus (inventor unknown but certainly at least as far back as the Sumerians in Asia. 2700 – 2300 BC).
(Charles Babbage and Alan Turing etc notable but their devices were largely or wholly mechanical)
All electronic computer - ENIAC (financed by United States Army and built at the University of Pennsylvania by many employees there - so there was no sole "inventor" as such)
Since “failure is an orphan and success has many fathers” there are still arguments about who invented all 3 - but that is as simple as I can make it.
Step-by-step explanation:
However, many people credit Philo Farnsworth with the invention of the TV. He filed a patent for the first completely electronic TV set in 1927 He called it the Image Dissector. Another inventor, Vladimir Zworykin, built an improved system two years later.
