The development of computers could be divided into the following stages: 1946 - 1957 was the first generation of vacuum tube computers. They used vacuum tubes as the main components. They were large, consumed a lot of power, and were slow. They were mainly used for scientific calculations. The software was a machine language, represented by ENIAC. 1958 - 1964 was the second generation of the transistor-based computer. The transistor-based computer replaced the electron tube, and its performance improved. It began to use high-level languages, and its applications expanded to data processing. 1964 - 1970 was the third generation of integrated circuit computers, which further reduced the size and power consumption. After 1970, it was the fourth generation of large-scale integrated circuit computers. Its performance continued to improve, and its applications were almost everywhere. Now, it was developing towards the fifth generation of artificial intelligence computers. " A Short History of the Future: Legends of the Intelligent Era " was equally exciting.

The history of computer development can be divided into the following stages: 1. ** Vacuum tube computer (1946 - 1957)**: This was the first generation of computers, with vacuum tubes as the main components. The world's first electronic digital computer, ENIAC, was born on February 14, 1946. It was mainly composed of a large number of tubes and was huge in size. For example, ENIAC used 18000 tubes, occupied an area of 150 square meters, weighed 30 tons, consumed about 150 kilograms of power, and could perform 5000 operations per second. This type of computer was mainly used for scientific calculations. It used machine language and had no system software. It used a magnetic drum and a small magnetic core as storage. The storage space was limited, and the input/output device was simple. It used punched paper tape or cards. 2. ** Crystalline computer (1958 - 1964)**: The second generation of computers used the crystal as the basic component. Compared to electronic 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. This improved the overall performance of the computer, greatly increased its computing speed, and significantly reduced its weight and size. The programming language began to use high-level computer languages, such as Fororan, Cogol, Algo160, etc. The computer began to be used in data processing and process control while performing scientific calculations. 3. ** Integrated Circuit Computer (1964 - 1970)**: With the development of semiconductor technology, integrated circuits became the main components of computers. The size of computers was further reduced, and the computing power consumption was reduced. In terms of software, they began to use a standardized programming language and the human-computer conversational Basic language, further expanding the application field. 4. ** Large-scale integrated circuit computer (after 1970)**: The scale of integrated circuits has further reduced the size of computers and further improved their performance. The application of software system engineering, theorization, programming automaton, software for network operating system and object-oriented programming, the application of microcomputers further expanded to almost all fields. 5. ** Artificial Intelligence Computer (Fifth Generation, under development)**: Its research fields generally include artificial intelligence, system architecture, soft engineering and support equipment, as well as the impact on society. This generation of computers 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 course of computer development, the hardware had gradually changed from huge, expensive, and limited performance to miniaturized, high-performance, and low-cost. The software had evolved from simple machine language to various high-level languages, and its functions had become increasingly complex and diverse. With the continuous advancement of technology, the application of computers in various fields also continued to expand. For example, from the early days, it was mainly used in scientific computing and military fields, and gradually expanded to business, industry, home, and now cloud computing, big data, artificial intelligence, and many other emerging fields.

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.

The development of computers could be divided into the following stages: 1. ** Mechanical computer era (1623 - 1945)** - [Early calculation tools: At first, people used their hands and simple chips to calculate. There were also methods such as "knotting ropes to record things".] The China abacus had a history of more than 2600 years and was a manually operated calculation aid. - [Important invention: French mathematician Blaise Pascal invented the adder, and then the difference engine that could perform the four basic operations appeared. Charles Babbage proposed the concept of the analytical engine (the first general-purpose computer prototype).] Representative models included the Pascal calculator (1642), the difference engine (1822), and the analytical engine (1837). 2. ** Vacuum tube computer era (1945 - 1958)** - ** Backstory **: During World War II, the United States developed electronic computers for military needs. - ** Representative computer and features **: In 1946, the University of Pennsylvania in the United States produced the world's first general-purpose electronic computer, ENIAC. It used vacuum tubes as logic components, large volume (covering an area of 170 square meters), high power consumption (power consumption of 150 Kilowatts), poor reliability, slow speed (5000 addition or 400 multiplication operations per second), used machine language, no system software, used magnetic drums, small magnetic core storage, simple input/output equipment (punched paper tape or card), mainly used for scientific calculations (such as the US Department of Defense's ballistic calculation). 3. ** The Age of Transcendence Computer (1958 - 1964)** - [** Backstory **: The invention of the transistor replaced the electron tube.] - ** Representative computers and features **: For example, the iPhone 7090 (1959), the ADC SPD- 1 (1960), etc. This type of computer was small in size, light in weight, long in life, low in heat generation, low in power consumption, and high in computing speed. Computer software had been greatly developed, with the emergence of high-level languages such as Fortrana and Cogol, and the use of monitoring programs (the prototype of the operating system). 4. ** Integrated Circuit Computer Era (1964 - 1980)** - ** Backstory **: The development of semiconductor technology has made integrated circuits the main components of computers. - ** Representative computers and features **: There are the iPhone System/360 (1964), Intel 4004 (1971), etc. The size of the computer was further reduced, the power consumption was reduced, and the speed and reliability were improved. 5. ** Microcomputer era (1980-present)** - ** Backstory **: The computer has been further miniaturized into a personal computer (PC), and the popularity rate has greatly increased. - ** Representative computers and their characteristics **: For example, the iPhone PC (1981), the Apple iPhone (1984), and the iPhone Thinkpad (1992). The popularity of personal computers further expanded the scope of computer applications, giving birth to emerging technologies such as the Internet and mobile computing.

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.
