History of the development of computer

When you use a computer or send e-mails, this solution requires the computer to solve several hundred.

Mathematical equations rapidly, it does not take only parts of a billionth of a second.

The first generation of computers: the first was the ability of computers solve complex equations, but time consuming; where computer scientists then face real challenges in converting images to computer formats can be addressed, in addition to huge sizes of computers and high material cost to memory.

The sizes of computers was very large, they contain a lot of wires and transistors, and the speed of the passage of electric current does not exceed two-thirds the speed of light, and because of the length of the wire it is necessary to power a long period of time passes by. 

Memory: The memory industry in the first generation is very expensive, and it is known that the increased memory capacity makes computer work faster, industry has memory capacity of 1 byte was requires 8 electrical circuits, and this means that the industry of memory 1024 byte (1 Kb) - a capacity is very low In the present day - needs to 8192 circuit.

And is interesting to note that computer capacity that was aboard the Apollo space and landed on the surface of the Moon did not exceed 64 Kb.

And in 1960 a group of scientists invented the integrated circuit, which helped to reduce the size of computer circuits and cost too much, and the small size of the computer with increased capacity.

And them make transistors chip sizes too small, also reduced the size of the computer, and say the price, so that the mobile phone has a much larger computing techniques of the giant central computers that were used in the seventies of the last century.
