In just a few decades since the birth of the first electronic computer in the world, computer technology has experienced rapid development. The average computing speed of electronic computers has reached millions, tens of millions, or even thousands or tens of trillions of times per second. Taking the logic elements that make up the computer hardware as a sign, to summarize, the development of electronic computers has roughly gone through several stages such as tubes, transistors, small and medium-sized integrated circuits to large-scale ultra-large-scale integrated circuits.
