Software design uses patterns. Research software design patterns. Note that these are not software development methods. They are patterns used in the actual software itself. Give examples of common software design patterns. Discuss the benefits of software design patterns. Design patterns typically focus on a specific area. There is another pattern, however, that is very general and all encompassing. Because of its broad applicability, I call it the Primary Pattern. It is most often referred to as the Input-Process-Output (IPO) pattern. This pattern presents a system/program as a sequence consisting of the following steps: Input Process Output Discuss why this pattern has such broad applicability. Give examples of this pattern in the business world. Give examples of this pattern in computer hardware. Discuss the kinds of actions that may be performed by each of its 3 steps.
