What was the abbreviated name of the first electronic computer
The abbreviated name of the first electronic computer was ENIAC.
The U.S. Department of Defense used the ENIAC for ballistic calculations.The ENIAC was a behemoth of a computer, using 18,000 electron tubes, covering an area of 150 square meters, weighing 30 tons, and consuming about 150 kilowatts of electric power, and capable of making up to 5000 operations per second, which seems insignificant now but was groundbreaking at the time. the ENIAC used electron tubes as components, so it was also known as the electron tube computer, the first generation of computers. Because of the large size of the tubes they used, ENIACs consumed a lot of power and were prone to heating up, so they couldn’t work for too long.
With the change of physical elements and devices, not only the mainframe of the computer has undergone a renewal, its external equipment is also constantly changing. For example, external memory, from the initial cathode ray display tube to the development of magnetic cores, magnetic drums, and later developed into a general-purpose disk, and now there is a smaller, larger capacity, faster read-only CD-ROM (CD-ROM).
What is the first generation of electronic computer acronym?
The world’s first generation of electronic computers is the birth of the first general-purpose computer acronym “ENIAC” was born in 1946 at the University of Pennsylvania. The United States used it for ballistic calculations.
It is a behemoth, with 18,000 tubes, covers an area of 170 square meters, weighing 30 tons, power consumption of about 150 kilowatts, 5,000 operations per second.
The ENIAC used electron tubes as components, so it was also known as the electron tube computer, the first generation of computers. Tube computers can’t work for too long because the tubes they use are very large, consume a lot of power, and are prone to heating up.
What was the name of the world’s first computer?
The world’s first recognized general-purpose electronic computer is the ENIAC (ENIAC), which was manufactured in the United States in 1946, and is an acronym for “Electronic Numerical Integrator And Computer” (ElectronicNumericalIntegratorAndComputer)。 ElectronicNumericalIntegratorAndComputer).
ENIAC – Electronic Numerical Integral Computer
ENIAC is a huge thing, covering an area of 170 square meters;
according to 30,000 square feet of housing prices, you have to take more than 5 million to put it.
ENIAC weighs 28 tons;
Sun Wukong’s golden rod is only 6.75 tons, which computes to more than the weight of four golden rods.
The ENIAC is very power-hungry, at 150kW, 150 kWh an hour, and a large portion of the power consumed is converted to heat — feel free to keep it hot.
The ENIAC includes 18,600 tubes inside, which can only work steadily for a few hours, and even then, the tubes still go bad very quickly, 19,000 tubes in the first year – nothing wrong with that, some tubes go bad over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over again.
The ENIAC used decimal for arithmetic, rather than the binary that computers use today.
The ENIAC could do 5,000 additions a second, which was 1,000 times faster than other computers of the time. But ENIAC did not store programs on its own, having only 20 storages, and it took hours or even days to prepare programs for it, even though calculations took only a few minutes.
From an engineering point of view, ENIAC was not a success:
R&D overruns of more than three times the budget – $150,000 was budgeted for and $486,800 was actually spent, but it was a national project, so money was not an issue;
Schedule was also greatly delayed – the ENIAC was built in 1943, but it had to be built in a few years. But ENIAC went on to play a huge role, and was used for nearly a decade for ballistic calculations, atomic bomb calculations, hydrogen bomb calculations, weather forecasting, cosmic ray research, wind tunnel design, and many other things, reflecting its value as a “general purpose computer”.
