Can you imagine the modern world without computers? I'm not, because every step is connected with computers. This story began in the distant 40s when the world began to learn about the creation of the first "computer" (electronic computing machines).
The history of the creation of the world's first computer
In 1942, the John Mochley project gave impetus to create the first computer, although the project itself was not fulfilled at the beginning. Once he became interested in one of the laboratories of the US Army, and in 1943 the first steps were made to create a car, called "Eniac". Money for the creation gave the Pentagon (who had to create new guns), and left a little less than $ 500,000.
By the way, ENIAC in terms of electricity turned out to be very voracious when it turned on - the lights of the nearby city every time tusknel. ENIAC (Electronical Numerical Integrator and Calculator) is a truly first computer that could be programmed.
Technical characteristics of the first computer:
- Weight reached 27 tons;
- Power - 174 kW - so much about spending a huge shopping center on a day off;
- Contained 18,000 electronic lamps, because there were no transistors and processors at that time;
- Memory - 4 kilobytes;
- He had an impressive size - occupied 135 sq.m.
- Performed up to 5,000 a second.
The most amazing is kilometers of wires that the computer was wrapped. It was programmed as a telephone communicator serviced by telephones.
Later, it began to be used not only to analyze cosmic radiation, but also to create a hydrogen bomb. While the computer was created, the war was over, but the studies did not stop and in 1945 held the first official test, which he stood. At the same time, about 1 000 000 IBM perflotes were processed. Despite the huge size and weight, the computer worked for about 10 years.
After 5 years, a transistor was invented, which marked the beginning of a decrease in computers.
Where and when did the first personal computer sold?
The concept of a personal computer has changed little over the next two decades. The introduction of the microprocessor has accelerated the process of creating a computer. IBM back in 1974 tried to create his first computer, but the attempt failed and sales were very low. IBM5100 - had cassettes as media, quite small weight and serious cost of $ 10,000.
He could also independently execute programs written in such programming languages \u200b\u200bas Basic and APL (it was created in IBM). Displayed 16 lines of 64 characters, the memory is about 64 KB, and these cassettes were similar to the audio stereo cassettes. But sales did not go, because there was no normal interface and the price was overestimated.
And you wondered - what will be the computers in 10 years?
IBM recently introduced its new mega-computer "RoadRunner". Its power is 1,000,000,000,000 (1 quadrillion) operations. It was created for the US Department of Energy, and consists of 6480 2-nuclear processors, and 12,960 IBM processors called. It includes 278 huge wardrobes, 88 kilometers of cables, weight - 226 tons, covers an area of \u200b\u200b1100 m², power consumption 3.9 MW, and costs amounted to $ 133,000,000.
