What are the advantages of using computer-generated visual aids? What are the drawbacks?

What will be an ideal response?

1. You can produce high-quality, sophisticated visuals and present them imaginatively; you can

easy to learn and to use. 2. It is tempting to make too many visual aids; your software might not match
the delivery system; the technology might fail.
