Using the South University Online Library or the Internet, research on hierarchy charts. Based on your research and using one of the appliances that you chose in W1 Assignment 2, complete the following tasks: Using Microsoft Word, Microsoft PowerPoint, or Microsoft Visio, create a hierarchy chart that reflects the appliance’s modules and how the modules call each other. Keep in mind that a hierarchy chart is different from a flowchart or pseudocode. In about two paragraphs, describe what your hierarchy chart represents. Support your responses with appropriate examples.
