The history of the development of computers, the history of the development of computers

Bogu Tongjin is a popular science fun created by the small code king**,From when did the computer appear in history to the current smart home,From the binary principle executed inside the computer to the encoding and decoding of files。 Let the children learn to code and understand some deep things around the computer.

The birth of the computer was a long time in the making. In February 1946, the first electronic computer, ENIAC, was launched in California, USA, using 18,000 tubes and 86,000 other electronic components, the size of two classrooms, but the speed of operation was only 300 various operations per second or 5,000 additions, costing more than $1 million. Although ENIAC has many shortcomings, it is, after all, the ancestor of the computer, which opened the prelude to the computer age.

And today's computers are getting more and more advanced, and they have reached the last calculation per second!

The first electronic computer ENIAC

Then computers, microcomputers, computers, notebooks, optical brains.

Introduction: The history of the development of computers.

Yes, that's not a problem.

The first generation: tube digital machine (1946-1958).

Features: large size, high power consumption, poor reliability. Slow (typically thousands to tens of thousands of operations per second), expensive, but laid the foundation for future computer development.

The second generation: transistor digital machines (1958-1964).

Features: Reduced size, reduced energy consumption, improved reliability, increased computing speed (generally 100,000 times per second, up to 3 million times), and greatly improved performance compared to the first generation computer.

The third generation: integrated circuit digital machine (1964-1970).

Features: Faster speed (generally millions to tens of millions of times per second), and reliability has been significantly improved, ** further declined, and the product is moving towards generalization, serialization and standardization. The application field began to enter the field of word processing and graphic image processing.

4th generation: LSI machines (1970 to present).

Features: In 1971, the world's first microprocessor was born in Silicon Valley, ushering in a new era of microcomputers. The application field has gradually moved from scientific computing, transaction management, and process control to the home.
