OK - For our week 1 questions - feel free to comment on one (1) or more of these questions or make up your own question (remember to also answer your question) (NEW THIS SEMESTER - NO DUPLICATE SUBMISSIONS - each student must submit new material so read the other student submissions before submitting yours - you can comment on someone else's submission as long as you are adding new material with a new citation: 1. Describe in detail the two agile methods and when you should use each method. 2. What are the disadvantages of each of the three system development methods? 3. Conduct some Internet research and look for examples of new approaches to systems development approaches. 4. Discuss when security issues need to be included in the systems development life cycle.

As you study the lecture slides and do the various exercises each week please comment on your experiences and new discoveries. Each student will be expected (which also means graded) to contribute at least two (2) separate relevant postings each week during the semester. You can start your own statement or add a comment to someone else's. Don't forget to include a citation in APA format from where you found your supportive information when answering these questions. This requirement is graded weekly and must be completed by the end of the day each SUNDAY beginning 29 JAN for WEEK 1 discussion board. I will start the discussions each week by posting one or more questions. So that's two (2) statements each week worth 4 points (2 points for each separate statement) a week.
Jaleah, I looked into the referenced text because hardware is one of my favorite components in CIS. So I wanted to look into the how the decisions on hardware components were made so I looked into Gordon Moore's law (Moore's Law) to see how it has been applied the determination is based because it's hard to keep up in this day and age with of the new technologies that are surfacing.
Computing power can be measured in many ways. You can take the amount of computing power a single pc has, or the total computing power in the world, etc. Moore 'normalized' his statement in terms of pricing. He argued that computing power for 'minimum component costs' would double. Roughly this means that for the same price, in 2 years you can buy a computer with twice the processing power or, in 2 years the same processing power will cost you half.
But if you look at the total computing power in the world, we are more than doubling. First of all, we are connecting computers together into clusters. 10 clustered machines have more computing power than each of them individually.
The second reason we are more than doubling is that the size of computers is becoming smaller and smaller, which makes it possible to add embedded computers to almost anything. Phones, tv's, dvdplayers, games, watches, dishwashers, almost anything has a microprocessor these days. So probably in the future the total amount of available computing power will increase faster than Moore's Law predicted
