The first history computer in the world the Eniac

the history of computing: Eniac

Hello, welcome to the blog: Techipii. I am Rafiq, you are on the Computer and Technology blog.
We are starting a new section called Did you know each time offers an update on a specific subject, and has, of course, as the main theme electronics.

So Today we are interested in Eniac, which is the acronym for electronic numerical integrator, and computer. It was in its time the first fully electronic computer. It could be reprogrammed to respond in principle to all computational problems.

It had been advanced ahead of the Germans, but he was electromechanical there was also the British colossus, we realize his name was called colossus, so he was not called to a very great future, this brave British computer.

History of the world's first computer Eniac.

The ENIAC has been financed since 1943 and received a project. px, it was operational from February 1946, so this computer was not really the state of the art of its time, because it had to be rewired each time to run a new program.

While For example, the Z3 calculator (Zuse 3) and the colossus computer did not have this drawback, and, indeed, we are far from imagining everything that had to be done, it was almost feet and hands at the time to program and reprogram a machine, whereas today by pressing the buttons and the button of his house and that one manages to do really very great things.

Eniac's first computer.

Look at this imposing machine, it consisted of 18,000 tubes, 1500 relays, 70,000 resistances, 10,000 capacitors, occupied a surface of nearly 170 m 2, and consumed 200 kilowatts.

Another feature is that the faults were frequent for this kind of machine. Obviously, the machine was still not super reliable, but one of the frequent causes of failures was the combustion of an insect on a hot tube, which broke the glass bulb, and these incidents were named bugs, which means insect in English, this brave ENIAC worked until 1955.

1 - How long did it take to calculate the power of the ENIAC computer?

It is good to calculate the trajectory of the shooting table to give you an idea of the power of this calculation. Men need on average 2.6 days, but at ENIAC this operation was performed in 3 seconds.

The ENIAC and well from 1947 was and began to be really terribly outdated since the invention of the transistors in the laboratories of the company indeed it's finally the knell of this machine and the technique of the tubes etc since the transistor He was smaller, lighter. more robust.

2 - When did the ENIAC computer stop working?

The ENIAC from 23/12/1947 was and began to really be terribly outdated, since the inventor of the transistor in the laboratories of the company DELL, and well finally rang the life of this machine and the technique of the tubes ... since the transistor was smaller, lighter and more robust.

3 - Why computer is called by the name computer?

The computer name comes from the verb: it means calculating, that is to say, calculating in English. Therefore, for the first time, using the term computer system refers to a team of 80 beautiful young women who occurred during the Second World War. Complicated American military trajectory calculations using a large analog mechanical computer.

From 1945 six of these women were chosen for the programming of the ENIAC.
