Software as an abstract entity
publish date: 2026/05/27 11:54:1.373492 UTC
Unlike a bridge or a car, software cannot be seen or touched directly. Its structure exists as code and data, not as a physical object.
Fill in the missing word: Software systems are (1) and intangible.
Correct Answer
(1) abstract
Explanation
