Students will work independently, or in groups, to explore computer response times for start-up; application and program run times;  serch engine speeds; and powering off the computer in safe and efficient ways using stopwatches and averaging load times.  Students will draw conclutions through a series of questions and comparisons to understand that variables in the user data collection, system byte sizes, storage limitations, multiple known and unknow tasks running behind the scenes, and/or internet stability/instability can all directly affect the computer's ability to respond accurately, and in a timely manner to user requests as well as perform as expected (with errors or success and/or lag time) and quickly. 

Just about everything you can do on a computer—checking your email, posting to Facebook, online banking and shopping—is powered by software. The people who come up with that software, and keep it working efficiently, are behind the scenes of a big portion of our lives.  Software engineering is an exciting career,.In this remix, some reflections questions for students have been added.
