You said in class that the one reason why IT fails is because users don't accept it....what does that mean exactly? People just choose to ignore the implementation of the new IT system?

Between the two most common approaches to SA&D, object-oriented analysis and design and systems development life cycle, are both used equally or is one approach more popular than the other? It seems that the SDLC is more widely used because we're ignoring the object-oriented analysis, but I don't want to assume...

The second in-class excel demo seemed pretty easy. I like how you go slow over the new material, it helps to not get lost. I feel that the homework won't be too hard, just might take a little longer to do than the first one.

I really have nothing else to say about it.

We went over the first excel assignment and I learned a couple new things, such as the 2 components in the what-if analysis: goal seeking and scenario manager. I don't know a lot about excel, except for the few basic things we learned in the Business Stats course. So I know how to find averages, standard deviation, the mean, and some other formulas, but I never knew about this what-if analysis.

I feel that now that I know about this data tool, I will definitely use it more often, especially for later on in the future. It is so simple to use, but yet so effective.

Another new thing I learned in class was using the dollar signs (ie, $B$2) to tell excel that it cannot change to another column or row when you want to click and drag to compute the other values. It has to stay in that cell. We were taught it in Stats, but I never fully understood its purpose.

I like doing these homeworks because it allows me to put everything that I am actually learning in the lectures into some real life situation. It helps keep me focused, where as with lectures I can sometimes drift in and out.




I have one more question, but it is about the final exam......What chapters are going to be covered on it? Just chapter 10?

I need help understanding a couple things for the test:

1) Is there a specific example of a virtual private network?

2) Could you give me an example of interoperability? I understand the definition, but I'm having trouble thinking of a real life example to fully understand the concept of it.

I was making notecards for the test and I came across some things that I had questions about...

1) for wide are networks, what do you mean by "think second life or MMOGS"?

2) under modems, what does "modulator-demodulator" mean?

3) Is Internet telephony like skype?
