Characteristics of computer software

(1) Intangible, no physical form, functions, characteristics and quality can only be understood through operating conditions.

(2) Software penetrates a lot of mental work, and people's logical thinking, intelligent activities and technical level are the keys to software products.

(3) Software will not age and wear out like hardware, but there will be defective maintenance and technical updates.

(4) The development and operation of software must depend on a specific computer system environment and dependence on hardware. In order to reduce dependence, software portability is proposed during development.

(5) Software is reusable, and software developed can be easily copied to form multiple copies.
