Discussion Questions
Chapter 6
- Given current trends in technology, what kind of system can you imagine upgrading to or buying new in 10 years? Which components would change the most? Which components would need to stay the same, if any? What do you imagine the entire system would look like?
- We are constantly being bombarded with new technology. We hear of new tools and system improvements from our friends, relatives, and advertisements almost daily. This chapter talks about upgrading current systems so that we can take advantage of some of the newer technology. Some improvements we absolutely need (more RAM, perhaps), whereas others we may just really want (such as a Blu-ray burner). What do you think are the societal, economic, and environmental impacts of our wanting to have the latest and greatest computers? Do you think the push toward faster and more powerful machines is a good thing?
- Mercury in screens and switches, cadmium in batteries and circuit boards, and the four to eight pounds of lead in CRT monitors are all toxic. Discarded machines are beginning to create an e-waste crisis. Who do you think should assume the cost of recycling computers? The consumer, the government, or the industry? What other options are there besides just throwing older computers away?
