Software is also called "soft equipment", broadly speaking, software refers to the collection of all documents. The term "computer" we usually refer to refers to a computer system that contains hardware and software.
The development of computer
From the birth of the world's first electronic computer has been just a few decades, computer technology has experienced rapid development. The average computing speed of electronic computers has reached millions, tens of millions, or even thousands or trillions of times per second. Marked by the logical components that make up computer hardware, 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.
