With the rapid development of computer technology, our life has undergone earth-shaking changes. This paper will discuss the development of computer science and technology from the aspects of computing speed, volume, input and output, environmental friendliness, failure rate and physical composition, so as to help readers better understand this field.

A huge leap in computing speed

The speed of the computer jumped from 5000 times/second to one million times/second, which greatly improved our calculation efficiency.

Volume slimming

Computers have become small and exquisite from once behemoths, and easily integrated into our daily life.

The Great Revolution of Input and Output

From paper tape to mouse and keyboard, from printer to high-definition display, the way of computer interaction has changed greatly.

Environmental friendliness

The emergence of industrial computers has greatly reduced our dependence on the environment and paid more attention to environmental protection.

Reduce the failure rate

Modern computer equipment is almost zero failure, saving time, effort and worry.

Upgrade of physical composition

From fragile electron tubes to stable transistors, modern computers have a longer life and a lower failure rate, which makes our work and life smoother.
