Final answer:
A virtual prototype is a software model that emulates a physical server's features, used extensively in design and development to simulate and test hypotheses before physical creation.
Step-by-step explanation:
A virtual prototype is a software construct that mimics the characteristics of a physical server. A virtual prototype is a software model that emulates a physical server's features, used extensively in design and development to simulate and test hypotheses before physical creation.
Both virtual and physical prototypes are important in the development process as they help in understanding and improving a design before it is implemented. The use of a computer-aided design and drafting (CADD) program allows the creation of a virtual prototype, which can simulate many aspects of a physical system, helping designers to identify potential flaws without the expense and time required to create a physical prototype.
Moreover, both types of prototypes should be developed around a hypothesis and have the capability to test this hypothesis, which is crucial in the iterative process of design and engineering.
