A brief history of computer development
The development of computers could be traced back to the early days of computing tools. At first, people used their hands and chips to calculate, and there were also methods such as "knotting ropes." The abacus, which originated in China, had a history of more than 2600 years. It was a manually operated calculation aid. In 1642, the French mathematician Blaise Pascal invented the adder, and then the difference engine that could perform the four arithmetic operations appeared. In 1837, Charles Babbage proposed the concept of the analytical engine, which was the prototype of the first general-purpose computer. In 1906, the American engineer DeForest invented the three-pole vacuum tube, laying the foundation for the birth of the tube computer. During the Second World War, there was an urgent need for computing speed. From 1943 to 1945, Mochley and Eckert of the Moore School of Electric Engineering at the University of Pennsylvania designed and manufactured the ENIAC. On February 14, 1946, the ENIAC was born. It was the world's first operational electronic digital computer. It used 18000 vacuum tubes, occupied an area of 150 square meters, and could perform 5000 operations per second. It was mainly used for scientific calculations. It used magnetic drums and small magnetic cores as storage. The input/output device was simple, using machine language and no system software. In 1943, the Mark I computer designed by Aiken of Harvard University and manufactured by BMW was debugged. In 1944, it was named the BMW Automatic Sequence Control Computer (Harvard Mark I). It was a relay computer, 51 feet long, 8 feet high, with 750,000 components inside. The manufacturing cost was about 400,000 to 500,000 US dollars. During the 1958 - 1964 crystal-based computer era, the invention of the crystal led to the reduction of computer size and energy consumption. The representative computers were the iPhone 7090 (1959) and the ADC SPD- 1 (1960). They were small in size, light in weight, long in life, low in heat generation, low in power consumption, and high in computing speed. In the era of integrated circuit computers from 1964 to 1980, integrated circuits became the main component with the development of semiconductor technology. The representative computers were the iPhone System/360 (1964) and Intel 4004 (1971). The size of the computer was further reduced, the power consumption was reduced, and the speed and reliability were improved. From 1980 to the present, it was the era of microcomputers. The computer was further miniaturized into a personal computer (PC). The representative computers of this era were the iPhone PC (1981), the Apple iPhone (1984), and the iPhone Thinkpad (1992). The popularity of personal computers expanded the scope of computer applications, giving birth to emerging technologies such as the Internet and mobile computing.

A brief history of computer development
The history of computer development can be divided into the following stages: The first generation was the electron tube computer. In 1946, the Moore Institute of Electrotechnical Engineering at the University of Pennsylvania created the world's first electronic digital computer," ENIAC," which was used to calculate trajectories. However, it was huge, costly, and inconvenient to use. However, the earliest electronic digital computer was actually the research result of John Atanasov, an associate professor in the Department of Physics, and his graduate student assistant, Cliff Barry. Mokley of the " ENIAC " research group plagiarized the result in 1941. This error was corrected in 1973. In 1990, John Atanasov was awarded the highest technology award in the United States, the " National Science and Technology Award." The first generation of computers used vacuum tubes as the main logic components. The arithmetic unit and controller used vacuum tubes. The main memory used mercury delay lines or magnetic drums. The external memory used magnetic drums and tape. It was mainly used for complex scientific calculations. The second-generation was a crystal-based computer, which was born in 1956. Compared to the first-generation computer, it was smaller in size and could be stored in a few larger cabinets. Its computing speed was also greatly improved. The third generation was the integrated circuit digital computer, which appeared in 1959. The fourth generation was the large-scale integrated circuit computer. In addition, there were also different types of computer development results. The abacus could be regarded as the earliest calculation tool, and the abacus was the earliest algorithm. The biocomputer used the protein molecules produced by bioengineering technology as the main raw material to make biochips to replace the semiconductor chips. The computing speed was 100,000 times faster than the latest generation of computers. It had strong anti-electromagnetic interference ability, automatic repair of faults, and the ability to imitate the human brain mechanism. The optical computer was composed of lasers, optical mirrors, lenses, and optical devices, which were used to perform digital operations, logic operations, information storage, and processing. Quantum computers were physical devices that followed the laws of quantum mechanics to perform high-speed mathematical and logical operations, store, and process quantum information. The concept originated from the study of irreversible computers, with the goal of solving the energy consumption problem in computers. And researchers have proven that classical computers can keep up with and surpass quantum computers through algorithms, but classical computers are prone to losing information.

A brief history of computer development in China
I recommend The Path of Cultivation for a programmer. The author, Skeleton White Rabbit, had a great imagination. He combined cultivation and programming. The main character programmer transmigrated to the cultivation world and programmed the cultivation world, like the dantian was the CPU and the spiritual root was the power source. The spiritual energy was divided into Yin and Yang like 0 and 1, and he could also use his mana to program his own spells. The book combined Yin Yang, Tai Chi, Eight Trigrams culture, and computer knowledge. It also had a programmer's interpretation of Tao begets one. The story was set strictly and logically. Although some of the content might be difficult for liberal arts students to read, it was very creative. It was obvious that the author had worked hard. It was worth reading even if the update was slow. Then he pushed Plutonium Dragon Domain. In a light novel written by Black Smoke, the male protagonist, Shilon Soderberry, was a dragon. After he transmigrated, his Silver Dragon mother, who was more than 200 years old, swore to use the Nuclear Peace Breath to bring peace to the world. When people had conflicts, they would play the Legend of Heroes card game instead of fighting. The main character was extremely powerful. This was a story about the growth of a dragon. Although the writing style was childish, it had a big imagination. It was a novel that transformed into a dragon. There were other similar dragon novels, and they were at the level of food. There was also 'The Man Standing at the Top of Ninja Realm'. This was a light novel written by Rain Duchen. The main character transmigrated into Nagato, and the story revolved around various assumptions such as if Nagato went to Moha. For example, if Yahiko did not die, there was a lot of room for imagination. It was just that the update was a little slow.

History of Computer Development
The history of computer technology can be traced back to the early 20th century. Vacuum tube computers: In the early 1940s, people began to use vacuum tubes to make computers. These computers were slow, required a lot of power, and were easily damaged. In the mid-1950s, people began to use the crystal to make computers. These computers were faster, more reliable, and did not require a lot of electricity. Integrated Circuit Computer: In the late 1960s, people began to use integrated circuits to make computers. These computers became more compact, faster, and easier to maintain. Personal computers: In the late 1970s, people began to manufacture personal computers. The emergence of these computers made it easier for people to process data and communicate. Internet: In the early 1990s, people began to use the Internet to transmit data. With the continuous development of the Internet, people can use the Internet to carry out a wider range of communication, learning, entertainment and other activities. As time passed, computer technology continued to develop and had a profound impact.
The History of Computer Development
The development of computers could be divided into several stages. Before 1946, there were relay computers, such as the Harvard Mark I, which was an mechatronics computer and the prototype of modern computers. 1946 - 1957 was the first generation of electron tube computers, represented by ENIAC. It used electron tubes, which were large in size, high in power consumption, and slow in speed. It was mainly used for scientific calculations. From 1958 to 1964, it was a transistor-based computer. The transistor-based computer replaced the vacuum tube and improved its performance. From 1964 to 1970, integrated circuit computers were introduced, and the size of computers was further reduced. After 1970, there were large-scale integrated circuit computers with higher performance. Now, it was still developing towards the fifth generation of artificial intelligence computers.

The History of Computer Development
The history of computer development can be roughly divided into the following stages: ** I. Early Prototype-Relay-Based Computer (1943 - 1944)** The relay computer was the earliest prototype of the modern computer. It had both mechanical and electrical characteristics. The Mark computer, designed by Aiken from the Harvard University Computer Laboratory and manufactured by iPhone, was the best example. In 1943, it was manufactured and debugged. In 1944, it was named the Harvard Mark I. It was very large, 51 feet long and 8 feet high. It was equipped with 750,000 various devices, such as binary-based switches, decimal-based switches, relaying, rotating wheels, and gears. The signal and power cables connecting the internal components were more than 500 miles long, and the manufacturing cost was about 400,000 to 500,000 US dollars. At this stage, the computer was powered by electricity, and digital calculations and information processing were completed through relay circuits. Compared to calculators in the pure mechanical era, the computing speed was faster and the functions were more powerful. ** Second, the first generation of vacuum tube computers (1946 - 1957)** In 1906, the American engineer DeForest invented the three-pole vacuum tube, laying the foundation for the birth of the tube computer. On February 14, 1946, the world's first electronic digital computer, ENIAC, was born at the University of Pennsylvania. Vacuum tube computers mainly used vacuum tubes as the main components. The computers of this period were huge, consumed a lot of power, were slow, had small storage capacity, poor reliability, difficult to maintain, and expensive. The software used was mainly machine language (the computer hardware could directly recognize the binary-code), mainly used for scientific calculations. The famous term "Bug" came from the first generation of computers. It was named after the small bugs that entered the vacuum tube and affected the computer's work. ** III. Second-generation transistor-based computers (1958 - 1964)** The transistor-based computer used the transistors as the basic components of the computer. Compared to vacuum tubes, the size of a crystal was smaller, the weight was lighter, the lifespan was longer, the efficiency was higher, the heat generated was lower, and the power consumption was lower. The overall performance was better than the first generation, the computing speed was greatly improved, and the weight and size were significantly reduced. The programming language mainly used high-level computer languages, such as Fororan, Cobol160, and so on. In addition to scientific calculations, computers were also used in data processing and process control. ** IV. Third Generation Integrated Circuit Computer (1964 - 1970)** With the development of semiconductor technology, integrated circuits became the main component of computers. This further reduced the size of the computer and reduced the power consumption during calculations. In terms of software, they began to use the standardized programming language and the human-computer conversational Basic language, further expanding the application field. ** V. Fourth-generation large-scale integrated circuit computer (after 1970)** As integrated circuits became larger, the size of computers became smaller and their performance improved. The software system was engineering, theoretical, and programming automaton. The software was for network operating systems and object-oriented programming. The application of microcomputers was further expanded, and they were involved in almost all fields. ** 6. Fifth Generation Artificial Intelligence Computer (Future Development Direction)** The research fields of the fifth-generation computer generally included artificial intelligence, system architecture, software engineering, support equipment, and the impact on society. Artificial intelligence would be the mainstream of information processing in the future. Therefore, the development of the fifth-generation computer would be closely integrated with artificial intelligence, knowledge engineering, and expert systems. It would have a learning mechanism that could simulate the work of the human visual nerve control system. It would have the ability to formally reason, associate, learn, and explain. It would be able to help people make judgments, make decisions, explore unknown areas, and obtain new knowledge. In the history of computer development, there were also some representative computer products, such as: the iPhone 726 was born in the late 1950s and was mainly used for large-scale data storage; the ICL2 was released in the late 1970s and was a model of commercial computers at that time; the Pilot ACE was one of the early general-purpose electronic computers that ran the first program in May 1950; the Control Data 6600 was the world's fastest computer from 1964 to 1969; There was also the HDI75 from East Germany and the EAI Pace, one of the earliest desktop computers. In addition, the CPU was also constantly developing, such as the Intel series, and the Intel series. "A Short History of the Future: Legends of the Intelligent Era" was equally exciting.
