Final answer:
A hierarchy chart, also known as a structure chart, outlines the structure of a program by displaying functions and their relationships, but it does not detail the steps within a function, for which flowcharts are used.
Step-by-step explanation:
The question revolves around the characteristics of a hierarchy chart in the context of programming or system analysis. A hierarchy chart, also known as a structure chart, is used to visualize the overall structure of a program or system by illustrating the various functions or modules and their relationships. However, it is important to note that a hierarchy chart does not show the actual steps taken within a function; it simply represents the function's existence and possibly its inputs and outputs, as well as its relationship to other functions. For understanding the steps taken inside a function, one must refer to the detailed design or flowcharts that lay out the logic of the function in a step-by-step manner.
