What are the characteristics of electronic computing compared with general computing tools?

Compared with general calculation tools, electronic computers have the following characteristics: (1) the operation speed is fast. A fast computer can perform more than one billion operations per second. A slow microcomputer can also perform 654.38+ million operations per second. (2) The calculation accuracy is high. The numerical value calculated by modern electronic computers can reach 64 bits. (3) Have the ability of "memory" and logical judgment. Electronic computers can record programs, raw data and intermediate results, and can also conduct logical reasoning and theorem proving. (4) It can be automatically controlled without manual intervention.

The application of electronic computers has rapidly penetrated into all aspects of human society. From the control of spacecraft and missiles, the research of atomic energy and artificial satellites, to industrial production, enterprise management and daily life, computers have been applied to varying degrees. It is asserted that there are traces of electronic computers in every activity in modern society.
