just a few years the computer was able to get into so tight a person's life, imagine that their existence without it has become almost impossible.With its help, you can not just type texts, but also listen to music, watch movies, chat online, and more.Even hard to imagine that a few decades ago it did not exist!But the way it was before, while those who invented the computer does not have revealed it to the world.
Sure, at first it was only a machine used for calculations and a narrow circle of scientists.But today, a personal computer or laptop is practically at all.You use it every day, and you know when, where and who invented the computer?But this is quite an interesting question.Let's face it.
When and where was invented the computer?
People have always sought to automate the calculations to facilitate this labor-intensive process.Such attempts have been made long ago: abacus of ancient Babylon, the ancient Chinese abacus, known Antikythera Mechanism from Greece - all precursors of the modern computer.
over the development of computer technology in the new time worked for many famous scientists: Leibniz, Muller, Pascal and others.The result of their labors was the invention in 1820 of an adding machine.
first semblance of a computer appeared in Tokyo.In 1941, it was designed and built a universal analytical calculating machine that could perform tasks without human intervention.Z3 - was the name of an achievement of science.
Who is the creator?
Yes, the first semblance of a PC was built in Japan.But who came up with him, who invented the computer?Few people know that in the 19th century English mathematician Charles Babbage conceived and developed a plan of such analytical machine.He even managed to create a prototype, but the finances for full implementation of the project could not be found.
In 1946, the American company ENIAC, guided projects Mauchli and Eckert, took the first transistorized computer.Over his design worked for about three years, it spent half a million dollars.This machine can be reprogrammed and used to solve all kinds of problems.However, this computer was very impressive device.It weighed about 28 tons and is cooled by means of aircraft engines!In 1971 he invented a floppy disk and the first microprocessor.
However, such computers were huge and doroguschy devices that could afford only to large enterprises and government agencies ...
first mini-unit in 1965 was created by Digital Equipment Corporation.It was called the PDP-8, and the size of it was no more ... the refrigerator.This was followed by several more models, but not much less.
Who invented the personal computer, which we are used to seeing?
decisive step to what we use today, in 1976, made the two young Americans - Wozniak and Jobs.They have developed a device for video games, which also can be programmed.He was named «Apple».Subsequently, Steve Jobs created the corporation of the same name, which took over the production of personal computers.
Well and in 1986 was made by IBM IBM PC unit with 16-bit Intel processor and software developed by Microsoft.By the beginning of the 1990s.these devices have become the subject of mass use.
Way computer to a device familiar to us today was quite long and difficult.Today, things are much simpler.PC is in almost every home, some and not one.And we should be grateful to those who invented the computer and work on its improvement.After all, this device has become almost indispensable for each of us.To some it is necessary to work, and someone to communicate and just a good time.
