In which year did the invention of computer go through several stages and characteristics?

1. When was the computer invented? 1946. The first real electronic computer in human history came out at the University of Pennsylvania on February 1946. The first electronic computer was developed in Oberding Weapon Test Range, USA, to meet the needs of trajectory calculation.

2. With the progress of science and technology and the rapid development of various computer technologies and network technologies, the development of computers has entered a fast and brand-new era. Computers have developed from single function and large volume to complex function, small volume and networked resources.

3. The development of computer has gone through several stages and features:

The first stage of development is electronics.

The era of computer management is from 1946 to 1956. 1946, the first electronic computer came out in the University of Pennsylvania. Designed by Neumann, it covers an area of170m2, 150KW. The operation speed is slower than others, which is a milestone in the history of computer development.

The second development stage is the computer age of transistors, from 1956 to 1964.

The third development stage is the computer age of integrated circuits and large-scale integrated circuits, from 1964 to 1970.

The fourth development stage is the computer age of VLSI, from 65438 to 0970.
