But it was born because of war.
In 1943, in order to decipher the German password, British mathematician Alan Turing designed the first electric mechanical computer called "Giant". Although this is just a hypothetical computer for decoding,

1959, the integrated circuit computer was born; in
1970, the large-scale integrated circuit computer was produced; in
, the new generation of microcomputers emerged in the 1980s.
On this basis, human beings usher in a new era of the Internet. 1957 Satellite In the Soviet Union on October 4, 1957,
