What is the development of computers in China?

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 development of computers is the improvement of hardware performance, the development of software technology, the popularization of network technology, the challenge of security issues, and the improvement of human-computer interaction.

1. Improvement of hardware performance.

With the continuous advancement of science and technology, the hardware performance of computers continues to improve. From the original supercomputer to the current microcomputer, the size of the mega scum computer is getting smaller and smaller, the performance is getting stronger and stronger, and the speed is getting faster and faster.

2. The development of software technology.

Software technology for computers is also evolving. From the initial assembly language to the current high-level programming language, the development of software technology has provided a more convenient and efficient means for the application of computers.

3. The popularization of network technology.

The development of computers is inseparable from the support of network technology. With the popularization of the Internet, the application range of computers is becoming more and more extensive. People can use computers to carry out various activities such as shopping, learning, and entertainment.

4. The challenge of security issues.

The widespread use of computers also poses security challenges. As hacking techniques continue to evolve, so does the security of computer systems.

5. Improvement of human-computer interaction.

Human-computer interaction is an important direction in the development of computers. With the continuous advancement of computer technology, the way of human-computer interaction is also constantly improving.

1. Fast calculation speed: the internal circuit of the computer is composed of various arithmetic operations at high speed and accurately.

2. High calculation accuracy: The development of science and technology, especially the development of cutting-edge science and technology, requires highly accurate calculations.

3. Strong logical operation ability: the computer can not only perform accurate calculations, but also have logical operation functions, which can compare and judge information.

4. Large storage capacity: The memory inside the computer has memory characteristics and can store a large amount of information, which includes not only all kinds of data information, but also programs that process these data.

5. High degree of automation: because the computer has the ability to store memory and logical judgment, people can incorporate the pre-programmed program group into the computer memory, and under the program control, the computer can work continuously and automatically without human intervention.

6. Cost-effective: almost every household will have a computer, which is becoming more and more common and popular, and the computer will become one of the indispensable electrical appliances in every household in the 21st century. Computers are developing rapidly, and there are desktops and laptops.

Hello, I hope my answer can help you.

1. 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.

2. The second generation: transistor digital machine (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.

3. 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.

4. The 4th generation: large-scale integrated circuit machine (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.
