Portable computing devices, when they first appeared, were very skeptical. The very first computer was created after World War II, on February 14, 1946, by American developers. It was extremely massive and consisted of many components, and by its software and technical properties it was not far from the calculator.
Creating the very first ENIAC computer
ENIAC has carried out a long and rigorous work to create a portable device. Of course, their research was multifaceted. But even before them there were attempts to create a computer. So, for example, even before the creation of the multi-ton ENIAC, similar prototypes were tested, but because of technical flaws they could not be created.
Scientists all over the world were concerned about creating the very first computer. The year of completion of development falls on 1946. On February 14, in the democratic United States, the ENIAC computer was presented to the public. In size, it looked like a small house more than a modern PC. Its weight was about 30 tons, and the number of electronic lamps could illuminate a small city - there were 18 thousand.
A little bit about the first computer
With such huge dimensions, the computing power was 5,000 operations per second. ENIAC worked for a little over 9 years and went to recycling. This giant was created by a group of five engineers. Like Internet technology, the creation of the very first computer was an order from the military. After its development and preliminary testing, the finished product was handed over to the US Air Force.
The computer was 17 meters long, and its head part consisted of 765 thousand parts of various kinds. The amount of development was about half a million dollars. The height of the car was at around 2.5 meters. The device was at Harvard. However, the creation date of the first computer formally fell on 1944, when it was first tested.
The parameters of the apparatus of the American model
As noted earlier, the computer model of 1946 did not reach the level of current portable computers. But its parameters and main characteristics:
- The computer weighed more than 4.5 tons.
- The total length of wires in the case was 800 kilometers.
- The shaft synchronizing the calculation modules was 15 meters long.
- The simplest (addition and subtraction) mathematical operations of a computer took 0.33 seconds.
- The division accounted for 15.3 seconds, and he multiplied a little faster, in just 6 seconds.
Enormous resources have been spent on creating the very first computer. The year of this event is 1946.
The very first attempts to create primitive electronic computing devices
In 1912, a scientist from the Russian Empire A. Krylov was able to develop the first machine for calculating complex differential equations. Already after 15 years, in 1927, developers from America tested the first analog computer.
Even the Nazis were engaged in the development of computers. A year before the start of World War II, in 1938, the German scientist Konrad Zuse created a digital computer model with a programming component, it was given the name Z1. And in 1941, “Zet One” underwent a series of modernizations and received the final name Z3. This model was much more like a modern laptop computer.
Finalization of the ABC prototype
The developer John Atanasov from the USA in 1942 led the development of a computer model ABC. But he was drafted into the army, and the creation of a computer was suspended for some time. His model began to test with the aim of studying another group of developers led by John Mockley. As a result, he began his own work to create an ENIAC computer.
He first gave rise to the binary system of calculus, which is still used in our PCs. The original purpose of the computer was to help the military in solving certain problems. They contributed to the automation of calculations during the bombing of artillery and air forces.
Creation of the first computer in the USSR
The Soviet Union did not lag behind world trends. In the laboratory S.A. Lebedev developed the first computer model throughout Eurasia. The first success of the Soviet electronic computing structure was followed by other, less loud, but extremely useful for science.
Soviet scientists developed and tested a small electronic calculating machine, abbreviated MESM. It was a model of a larger overall apparatus for computing.
