Usage notes 
- (any of various data structures): The exact usage of the term array, and of related terms, generally depends on the programming language. For example, many languages distinguish a fairly low-level "array" construct from a higher-level "list" or "vector" construct. Some languages distinguish between an "array" and a variety of "associative array"; others have only the latter concept, calling it an "array".
Derived terms
