Electronic technology is a new technology developed in western countries such as Europe and America at the end of 19 and the beginning of the 20th century. It was first invented by American Morse in 1837, American alexander bell in 1875 and British physicist Fleming in 1902. Electronic products developed most rapidly and were widely used in the 20th century, and became an important symbol of the development of modern science and technology.
The first generation of electronic products centered on electron tubes. In the late 1940s, the first semiconductor transistor was born in the world. It has been adopted by many countries because of its small size, portability, power saving and long service life, and has replaced electron tubes in a large range.
At the end of 1950s, the first integrated circuit appeared in the world, which integrated many electronic components such as transistors on a silicon chip, making electronic products more miniaturized. Integrated circuits have developed rapidly from small integrated circuits to large-scale integrated circuits and ultra-large-scale integrated circuits, thus making electronic products develop in the direction of high efficiency, low power consumption, high precision, high stability and intelligence.
