The History of Computer Development
The history of computer development could be divided into several stages. In the era of mechanical computers (1623 - 1945), early calculation tools developed from two-handed chips to abacuses, and French mathematicians invented the adder. In 1946, the world's first general-purpose electronic computer, ENIAC, was born, starting the era of vacuum tube computers (1945 - 1958). It used vacuum tubes and was large in size. Then, the era of the transistor-based computer (1958 - 1964) came, and the size of the computer shrank. In the era of integrated circuit computers (1964 - 1980), computers were further optimized. From 1980 to the present, it was the era of microcomputers. Personal computers were popularized and gave birth to many emerging technologies.

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.

I recommend The Path of Cultivation for a programmer. This novel was super interesting. A programmer transmigrated to the cultivation world and programmed cultivation. It was as if his dantian had become the CPU and his spiritual root was the power source. In the book, Reiki was treated as 0 and 1, the cultivation process was like a computer, and the casting of spells was like a program. It combined Yin Yang, Tai Chi, and Eight Trigrams culture with the computer in a particularly wonderful way. The way Dao Shengyi used the programmer's thinking to interpret it was cool. Moreover, the setting was strict and not made up. It could be seen that the author had put in a lot of effort. He had collected 14 computer books and even read 4 of them. The first 33 and 66 chapters were super cool for the protagonist to write the algorithm optimization method. The latest storyline was also very cool for the protagonist to witness the changes in mathematics. Although the update might be slow and could be interrupted, as long as it was bearable, it was worth watching. This creativity was really amazing.
