This computer has more than 18,000 shared power in the tubes, an area of 170m2, the total weight of 30t, power 140kw, computing speed of the 5000 additions per second, 300 times multiplication.
In just 50 years after the tubes, transistors, integrated circuits (IC) and ultra large scale integration (VLSI) four stages of development, computer has become smaller and smaller, more powerful, more and more widely，and its price is also getting lower and lower, currently moving intelligence (fifth generation) computer direction.
1. The first generation of computer
The first generation of electricity in the computer is from 1946 to 1958. They are larger, lower operation speed, storage capacity is small and expensive. Not easy to use, in order to solve a problem, the complexity of programmed elusive. This generation is mainly used for scientific computing, scientific research only in the key sectors or departments.
2. Second-generation computer
Second-generation computer is from 1958 to 1965, they all use the transistor as an electronic device, the operation speed than the first generation of faster computers in recent times, the volume of several one-tenth of the original. In terms of software to start using computer algorithms language. This generation not only for scientific computing, but also for data processing and transaction processing and industrial control.
3. Third-generation computer
The third generation of computer is from 1965 to 1970. The main characteristics of this period is, the small-scale integrated circuits for electronic devices, and operating system appears to make more powerful computers, applications and more wide.
