1951univac-1-The first commercial computer system was born, designed by J. Presper eckert and John Moakley. It was used by the U.S. Census Bureau for census, which indicated that computers entered the era of commercial application.
Because UNIVAC- 1 is a computer using transistors, UNIVAC- 1 is the representative of the second generation computer. Computers have now developed to the fourth generation.
1950, Dr. von Neumann designed the world's first computer EDSAC with the function of storing programs. Its main feature is that it uses binary and mercury delay line as memory, and instructions and programs can be stored in the computer.
1951March, the first universal automatic computer UNIVAC-I designed by the main designers of ENIAC, Mochili and eckert, was put into use. It can not only do scientific calculation, but also do data processing.
For the first time, UNIVAC- I used tape drives as external storage. Firstly, the reliability of the system is improved by using parity check method and double operation circuit, and the automatic programming experiment is carried out for the first time.
