Stages of development of computers:

Four stages of development:

The first stage of development: 1946-1956 in the era of tube computers. In 1946, the first electronic computer was introduced to the University of Pennsylvania.

It was designed by von Neumann. It covers an area of 170 square meters, 150kw. The computing speed is slow, and no one is fast yet.

It is a milestone in the history of computer development. The full name of (ENIAC) (Electronic Numerical Integator and Calculator) is "Electronic Numerical Integator and Calculator".

The second stage of development: the computer age of transistors in 1956-1964: the operating system.

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

The fourth stage of development: 1970-present: the computer age of VLSI circuits.

Brat.. You're taking the exam. Engage in fraud, huh?

There are a total of 5 stages of development:

The first stage of development was the era of tube computers. In 1946, the first electronic computer was introduced at the University of Pennsylvania in the United States, and it was designed by Mowkeley Eckert. It covers an area of 170 square meters, 150kw.

The speed of computing is not as fast as anyone else, which is a milestone in the history of computer development.

The second stage of development is the computer age of transistors.

The third stage of development is the computer age of integrated circuits and large-scale integrated mode inspection circuits.

The fourth stage of development is the computer age of VLSI circuits.

The fifth stage of development is the era of intelligent weighing and limb computers, which combine the collection, storage, processing, and communication of information with artificial intelligence.

Hello, the development of electronic computers has gone through a total of 4 stages, and I will explain each stage separately.

The first generation: Tube digital machine Keizao (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.

The 4th generation: Large-scale integrated electric escort hitchhiker (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 calculation, transaction management, and process control to the family.
