Think It Over
Software as a Service
Suppose you had the chance to buy a productivity suite like Microsoft Office for a certain price
and keep that version indefinitely, or to subscribe to a service that enabled you to use Office for as
long as you continued paying the subscription fee. Suppose that the subscription cost was 1/30th
per month of the cost to buy it outright. Which would be a better value for you, and why?
What if it were a game that you could either buy or subscribe to? Would you rather buy it outright
and be able to play it forever, or would you rather subscribe to it?
Shopping for Tablet PCs
Suppose you are shopping for a tablet PC for use in your classes. Using the Internet, research
at least one model of iPad, one tablet that has the Windows OS, and one model that uses the
Android OS. Then answer the following questions:
Which tablet has the fastest processor and the most memory?
Which tablet OS has the most apps available for it?
Which model has the longest battery life?
Which tablets have the capability of attaching external keyboards?
Which tablet has the largest screen size and the highest resolution?
What features do you personally find most important, and which model would serve those
needs best?
Sharing Wi-Fi
Suppose your family pays for broadband Internet service, and you have a wireless router that
allows everyone in the family to share the Internet connection. The wireless router has security
on it, so that a code is required to connect to it. This prevents your neighbors from using your
Internet connection without permission. A neighbor asks for the code so he and his family can use
your Internet connection. What do you say? Explain how you came to your decision.
No, it would be unfair to the ISP for you to use the Internet without paying for it. You must
pay for your own separate connection.
Yes, you can use it, but you must pay me for part of the expense of the service.
Yes, you can use it for free. Here is the code.
Some other answer (explain).
