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. It would have the ability of formal reasoning, association, learning, and explanation to help people make judgments, make decisions, explore unknown areas, and obtain new knowledge. With the development of the Internet age, computers were interconnected with the popularity of the Internet. Cloud computing, big data, artificial intelligence, and other emerging technologies were driving the continuous development of computers. Computer technology was still constantly being innovative. Research in cutting-edge fields such as quantum computers and biological computers was also exploring more possibilities for future computers.

A brief introduction to the history of Beiqi
Northern Qi (550 - 577) was the Northern Dynasty regime established by Gao Yang during the Northern and Southern Dynasties of China. Because the emperor was Gao, it was also known as Gao Qi. It had six emperors and ruled the country for 28 years. At the end of the Northern Wei Dynasty, Gao Huan became a powerful minister of the Northern Wei Dynasty after he took over the Xianbei forces in the six towns. After the Northern Wei split, Gao Huan was granted the title of King of Qi by the Eastern Wei Dynasty and defended Jinyang for a long time. In the seventh year of Wuding (549 years), Gao Huan's second son, Gao Yang, presided over the government affairs after his father and brother passed away one after another. In the following year, he forced Emperor Xiaojing of the Eastern Wei Dynasty to abdicate and establish Qi as emperor. During Gao Yang's reign, he strengthened the central power internally and sent troops to repel the Khitan, Worm, Shanhu, Kumoxi, Turkic, Southern Liang and other forces, expanding the territory of Northern Qi and strengthening its national strength. After Gao Yang's death, his younger brother Gao Yan killed his son Gao Yin and usurped the throne. In the second year of Huangjian (561), Gao Yan passed away and passed the throne to Gao Zhan. During the reign of Gao Zhan and his son Gao Wei, they favored the forces of He Shikai and excluded the Han scholars and dignitaries. The bureaucracy was complicated, the people were heavily enslaved, and the national strength weakened. Gao Wei also killed the general and the king of Lanling Gao Changgong because of suspicion. In the first year of Longhua (576), the Northern Zhou attacked the Northern Qi. Gao Wei wanted to flee to the Turks but failed to abdicate to the eight-year-old Crown Prince Gao Heng. In the second year of Longhua (577), Jingdou Ye City was captured by the Northern Zhou army. Gao Heng and Gao Wei were captured while fleeing, and Northern Qi was destroyed. In the same year, the Northern Zhou Dynasty sentenced Gao Wei, Gao Heng, and others to death under the name of Gao Wei's involvement in rebellion. The rulers of Northern Qi were mostly dissolute, tyrannical, and mentally unstable. There were cases of fathers and sons having wives, brothers having wives, and other things that violated human relations. Thus, they were called the "Beast Dynasty." However, the rulers of the Gao family were mostly handsome, such as Gao Changgong, the King of Lanling.
