Electronic technology is an emerging technology that began to develop at the end of the nineteenth century and the beginning of the twentieth century. It developed the fastest and most widely used in the twentieth century and became an important symbol of the development of modern science and technology.

The first-generation electronic products were centered on electron tubes. At the end of the 1940s, the world’s first semiconductor triode was born. It was quickly used in various countries for its compactness, light weight, power saving, and long life, replacing electron tubes in a wide range. In the late 1950s, the world's first integrated circuit appeared. It integrated many electronic components such as transistors on a silicon chip, making electronic products more compact. Integrated circuits have rapidly developed from small-scale integrated circuits to large-scale integrated circuits and very large-scale integrated circuits, so that electronic products are developing in the direction of high efficiency, low consumption, high precision, high stability and intelligence. Therefore, it is believed that the development of electronic computers has gone through the above four stages.
