Final answer:
A system flowchart illustrates the overall data processing cycle and is not specifically about the logic used in a program, making the statement false.
Step-by-step explanation:
The statement 'A system flowchart describes the specific logic used to perform a process shown on a program flowchart' is false. System flowcharts and program flowcharts serve different purposes. A system flowchart illustrates the data processing cycle for a system, showing how data flows through the system and the various processes it undergoes. It also includes the hardware components that are used and their interconnections. On the other hand, a program flowchart is more specific and represents the logic behind an individual program or part of a system. When dealing with flowcharts, processes such as unit conversions typically follow the same logical steps, as shown in various figure references which illustrate this consistency.
