What is computer system? |
Computer & it's history:
Thus, computer is a machine, but compared to other machines, its age is very short, it has also been invented by humans according to their needs, but unlike other inventions, computers have covered the whole world in a very short period of time.
Today, any country that is developing needs computers as much as possible.
Without computers in developed countries, there is no safe movement of trains, no flights of airplanes, no business of banks, and no computers for space travel.
He is also a great expert in calculation, no matter how difficult the calculation is, the computer solves it within a second. The memory of the computer is very fast, whatever you tell the computer, it remembers it exactly right and tells it immediately when asked without mistakes and delays.
Different stages of computer invention:
The beginning of the invention of the computer is very interesting and it has passed through many stages to become the owner of the present qualities.
It happened that one day in 1642, a young man named Blaise Pascal was sitting in his father's office in France doing calculations. The work was so much that he was tired of doing it.
He thought that he wished this work could be done by a machine. So how good is that young man who was full of ambition.
Finally, one day he invented a machine that could collect hundreds of thousands.
People were very surprised to see this machine.
What happened then, people took this machine with their hands. This second step in the invention of computer solved many problems of people.
Linus introduced the world to another new rule and mathematics through computer, which today you call swimming system. Actually the computer works under the same system.
As a result of this effort of Lions, the computer became famous all over the world. Then the scientists started day and night trying to somehow make this machine better and more useful.
During this time, Charles Bay Beach, a British mathematician, refined this machine further. After passing through this stage, the name of this machine came to be computer.
The miracle was that the machine could run very well without electricity. Two American scientists, John W. Mcliy and B.P Eckert, realized the capabilities of the computer and decided that it could be improved even further.
So both of them taught some special and new leaders of computer literacy and presented the computer in a better form than before.
He also exposed the computer to electricity and named the computer Anaic. Then the computer revolutionized the industrialized countries. The computer was originally developed by an American scientist, Bush.
Computer parts by nature of function:
The working process of computer is very interesting.
There are many parts inside, but nature of the work It has five main parts.
The input part, the second part is the calculation (Arth and Logic), the third part is the memory (Storage or Memory), the fourth part is the monitoring (Control) and the fifth and last important part is called the output (Out Put).
Through these important parts The computer demonstrates its capabilities. He tries to defeat the human mind in any way.
Although B is the creation of human mind. Early on, an American scientist said that:
‘‘If a computer became capable enough to mimic the human mind, it would be the size of a multi-story building and require as much electricity as Niagara Falls to run it.
It is produced and all the water of Niagara Falls will be needed to cool it”
but today the words of this American scientist have become meaningless because the computer has developed so much that instead of increasing its size, it is constantly decaying and this The performance is increasing day by day.
Now the computer is already quite small, while it can work at a very high speed, due to its ability, it can be said that the day is not far when the computer will surpass the human mind in some respects.
