The origin and development history of computers
The development of computers had gone through a long process: ** I. Early Exploration and the Era of Mechanical Computer (1623 - 1945)** 1. ** Early exploration ** - In the 17th century, mathematicians and inventor began to use mechanical devices to calculate. In 1623, the German mathematician Wilhelm Schick designed a mechanical calculator that could perform addition, multiplication, and division operations. Although it was not widely used, it laid the foundation for the development of computers. 2. ** The development of mechanical computers ** - In 1642, French mathematician Blaise Pascal invented the world's first mechanical computer, the Pascal calculator, which could perform addition and substitution operations. - In 1822, the British mathematician Charles Babbage proposed the concept of the difference engine and designed the analytical engine based on it. It was considered the prototype of the first general-purpose computer, but it was not fully realized due to technical and financial problems. ** II. The Birth and Initial Development of Electronic Computers (1945 - 1958)** 1. ** Electronic Numeric Integration Computer (ENIAC)** - In 1946, John Mochley and Presbo Eckart of the University of Pennsylvania developed the world's first electronic digital integral computer (ENIAC). It used about 18,000 vacuum tubes and 70,000 resistances, covered an area of 170 square meters, weighed 30 tons, and could perform about 5000 addition operations per second, marking the beginning of the electronic computer era. 2. ** Initial development and application ** - In 1949, the first stored-program computer, Edvacs, was born. It adopted the concept of "stored-program" proposed by van Neumman, which meant that programs and data were stored in the computer's memory, and the computer could automatically access instructions and execute them. This had a profound impact on the development of subsequent computers. ** 3. The Age of Transcendence Computer (1958 - 1964)** - With the advancement of science and technology, the transistors replaced vacuum tubes as the main components of computers. The advantage of the crystal was its small size, low power consumption, and long lifespan. Before ENIAC, humans had also developed mechatronics computers, such as the Harvard Mark I computer, which was manufactured and debugged in 1943 - 1944. It was a relay computer with both mechanical and electrical characteristics. It was the earliest prototype of modern computers. Before the invention of the computer, humans had also experienced the process of counting with their fingers and using tools such as stones and ropes to assist in counting. The development of these counting methods also provided a certain foundation for the invention of the computer. "A Short History of the Future: Legends of the Intelligent Era" was equally exciting.

A brief introduction to the history of computers
The history of computer development can be divided into the following stages: 1. ** The first generation of vacuum tube computers (1946 - 1957)**: Using vacuum tubes as the main components, it was featured by its huge size, high power consumption, slow speed, small storage capacity, poor reliability, difficult maintenance, and expensive. It used machine language and was mainly used for scientific calculations. For example, the world's first electronic digital computer, ENIAC, used 18000 tubes, occupied an area of 150 square meters, weighed 30 tons, consumed about 150 Kilowatts of power, and could perform 5000 operations per second. It used a magnetic drum and a small magnetic core as a storage device. The storage space was limited, and the input/output device was simple. It used punched paper tape or cards. The famous term "Bug" came from the first generation of computers. It originated from a small bug that drilled into a vacuum tube and affected the computer's work. 2. ** Second-generation transistor-based computer (1958 - 1964)**: Based on transistor-based devices, transistor-based computers are smaller in size, lighter in weight, longer in lifespan, more efficient, less heat-generating, and lower in power consumption than electronic tubes. The overall performance was improved compared to the first generation, the computing speed was greatly improved, and the weight and volume were significantly reduced. Advanced computer languages such as Fortrana, Cogol, Algo160, etc. were used for scientific calculations, data processing, and process control. 3. ** The third generation of integrated circuit computers (1964 - 1970)**: With the development of the semiconductor technology, integrated circuits became the main components of computers, further reducing the size of computers and reducing computing power consumption. 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. ** The fourth generation of large-scale integrated circuit computers (after 1970)**: The scale of integrated circuits further reduced the size of computers and further improved their performance. The software system engineering, theorization, and programming automaton involved the use of network operating systems and object-oriented programming. The application of microcomputers was almost everywhere. 5. ** Fifth generation artificial intelligence computer (in development)**: Its research fields generally include artificial intelligence, system architecture, soft engineering and support equipment, as well as the impact on society. It 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.

These early computing devices laid the foundation for modern computing devices. 2. ** Vacuum tube computer stage **: - From 1937 to 1942, John Vincent Atanasov, an associate professor in the Department of Physics at the University of Pennsylvania, and his collaborator, Cleverford Bailey, successfully developed the ADC machine. It used 300 electron tubes and adopted the idea of binaries, but it was not programmed. It was only used to solve linear equations, and its storage function was weak. - In 1943 - 1944, British engineer Thomas Harold Flowers led the development of the Giant Machine. There were two types (Mark 1 and Mark 2), which were used to decipher German intelligence. Based on the Turing method and binary-system, the programmer was achieved by switching, turning, and connecting boards. - From 1943 to 1946, with funding from the U.S. Army, Presbo Eckart, a graduate student at the Moore School of Electric Engineering at the University of Pennsylvania, and John Mochley, the head of the Physics Department at Ursinas College, jointly led the development of ENIAC. It was born at the University of Pennsylvania on February 14, 1946. It was the first general-purpose programmed computer. It used the decimal system and had no storage function. It was mainly composed of a large number of tubes. It was huge, covering an area of 150 square meters and weighing 30 tons. It consumed about 150 Kilowatts of power and could perform 5000 operations per second. The input/output equipment was simple. It was mainly used for scientific calculations, such as the trajectory calculation of the US Department of Defense. - From 1945 to 1949, Morris Wilkes of the University of Cambridge, England, borrowed the ideas of the manuscript of van Neumman and developed the world's first storage electronic computer, Edsac, in May 1949. The real Edvac-based computer was only successfully developed in August 1949. 3. ** Crystalline computer stage **: Since 1956, the use of the crystal in computers, and the crystal and magnetic core memory led to the creation of the second generation of computers. Compared with the electron tube computer, the crystal computer was smaller, faster, lower power consumption, and more stable. In the early days, it was mainly used for large amounts of data processing in atomic science. 4. ** Integrated circuit computer stage **: Faster computer speed (millions of times per second to tens of millions of times per second), significantly improved reliability, lower prices, products moving towards unitization, serialization, and standards, and applications entering the field of word processing and graphics and image processing. 5. ** Large-scale and ultra-large-scale integrated circuit computer stage **: Since 1970, large-scale and ultra-large-scale integrated circuits (LSIs and VLSIs) have been used for logic components. In terms of software, there were database management systems, network management systems, and object-oriented languages. In 1971, the world's first microchip was born in Silicon Valley, creating a new era of microcomputers. "A Short History of the Future: Legends of the Intelligent Era" was equally exciting.
