It's big, and it's going to fill a big room. Born in the United States in 1946 by Von. Neumann proposed and designed.

The first computer was designed by the British mathematician Charles Babbage in the 19th century and was called the "Babbage Giant Computer Annihilation", but due to technical constraints and financial problems, the computer was never fully built. The first real computer was a spinal sail called ENIAC designed and built by John Bickner and John Presper of the University of Pennsylvania in the United States in the 40s of the 20th century.

So far, more than 50 years have passed, and the speed of development is rare in the history of modern science and technology. However, today's computers still leave much to be desired.
The computing speed of the computer is still very slow to solve some problems, such as long-term weather forecasting, global environmental simulation, ****, plasma nuclear fusion research and other problems, and the use of current computers is still somewhat insufficient.
At present, computers can only work strictly according to the programs set by people, so they are not good at solving, and cannot fundamentally solve some intelligent problems, such as language potato recognition, image recognition, expert systems, etc., because people cannot translate their own understanding into strict machine instructions.
In addition, the "cell" of the computer, the integrated circuit, cannot continue to develop indefinitely.
People and grandchildren have no foresight to change their pretenses, and there must be near-term worries. Today, when computer technology is booming, scientists have also begun to open up new ways to research and develop a new generation of computers.

In March 1978, *** made a decision on behalf of *** that the 100 million times supercomputer would be built by the National University of Defense Technology. Tzu Yun Gui served as the commander-in-chief and chief designer of this task. They made full use of the favorable conditions of opening up to the outside world to design an overall plan for China's 100 million times giant aircraft that is not only in line with China's national conditions but also compatible with the international mainstream giant aircraft.
Organize elite soldiers to tackle key problems, and finally make it possible in the exploration of new technologies, new processes, and new theories"Milky Way"Compared with the international mainstream giant machine, the 100 million times giant machine has made creative development in 10 aspects, filling the gap of the domestic giant machine, making China one of the few countries in the world that has developed a giant computer, and is widely used in oil exploration, meteorological forecasting, engineering physics research and other research fields. He was the first to advocate the research of intelligent computers in China, responsible for the establishment of the intelligent computer professional group of the China Computer Federation, and successfully presided over the international academic conference on the new generation of computer systems.
On December 22, 1983, China's first "Galaxy" supercomputer, which operates more than 100 million times per second, was successfully developed in Changsha by the Computer Research Institute of the National University of Defense Technology. It fills the gap of domestic supercomputers and marks China's entry into the ranks of the world's development of supercomputers.
In April 1957, China ordered the M-3 computer and computer drawings through the first channel. On the basis of the investigation and the acquisition of drawings, the development work began. Headed by Zhang Zichang and Mo Gensheng, the M-3 (code 103) computer engineering group was organized.
Through the efforts of all the research and development personnel and the close cooperation of the Beijing Cable Power Plant, China's first digital electronic computer was successfully developed on August 1, 1958. This tube computer, with an operation speed of 30 times per second, fills the gap of modern electronic computers in China.
On August 1, 1958, the developers of the 103 computer part gathered in front of the machine to celebrate the birth of China's first digital electronic computer.
On August 1, 1958, China's first digital electronic computer, the 103 machine, was born, with an average operation speed of 30 times per second. With the improved configuration of core memory, the computer's computing speed has been increased to 1,800 operations per second. The Beijing cable power plant produced 36 units, designated as DJS-1 computers.

China's first semiconductor mainframe computer 103 (fixed-point 32 binary bits, 2500 times per second) was born in the Institute of Computing Technology of the Chinese Academy of Sciences and was delivered in 1958.
In 1985, the world's first laptop was born. In the 10 years since, laptops have slowly entered the field of vision of Chinese users. In 1996, laptops accounted for less than 1% of the total PC market in Chinese mainland.
There is no specific time.
M8 is China's first smart phone, carrying too many Chinese people's expectations for independent intellectual property rights of mobile phones, from 2007 to 2009, after many ups and downs, M8 was officially launched on February 18, 2009.
