The term "dependent logical unit" refers to a set of instructions that rely on the output of another set of instructions to function properly. Synonyms for this term include "subroutine," "subprogram," and "procedure." These terms all refer to a small section of code that performs a specific task and can be called upon by other sections of code. Another synonym, "module," refers to a larger section of code that may contain multiple subroutines or procedures. In object-oriented programming, the term "method" is often used to refer to a function or procedure that is part of a class and can only be called through an instance of that class.
