What is the biggest difference between electronic computers and other mechanical equipment?

The biggest difference between a computer and other machines is that it is a machine that can execute programs, which determine the behavior of the machine. All tangible parts of a computer, such as components, circuit boards, power supplies, etc. , called hardware. Only the hardware machine is called "bare metal", and nothing can be done. Only by loading the program into bare metal can it show its vitality. Because the program is intangible and plastic, it is called software. Hardware and software can form a complete computer, and both are indispensable. Hardware is the "driver" of computer, and software is the "soul" of computer. If only simple software is installed, the computer is like a "moron"; The same hardware, excellent software, become brilliant.
