A high fidelity prototype closely resembles the final product. A low fidelity prototype would never be mistaken for the final product.

What will be an ideal response?

a. It is easy to build.
b. It is not necessary to wait for the developers to create a computer-based prototype.
c. It is fast to change. Erasing one link name and writing in another is far quicker with a pencil than with any web-authoring tool.
d. It maximizes the number of times the design is refined before anything is committed to implementation.
