What is Semantics (Computer Science)?

In computer science, semantics is the mathematical study of the meaning of different programming languages. One of the ideas in programming semantics is that linguistic representations (symbols) depict logical outcomes, while phrases and sets of words interpret different instructional formats for both humans and machines. More simply, semantics describes how different programming languages are interpreted and used by different types of developers or machine-readable systems. In contrast, programming syntax is used to describe the arrangement of words and phrases within a programming language.
