About this interactive
What you're doing: sorting brief scenario cards into five OS-type bins — Desktop, Server, Mobile, Embedded, and Real-Time. Why it matters: an OS is chosen to fit its environment, not the other way around, so the clues in a scenario (who interacts with it, how many users it serves, whether a late response is a failure) are what tell you which type belongs. How to use it: read each scenario, drop it in the bin it fits, and pay attention to the Embedded and Real-Time cards — both run fixed-function devices, but only Real-Time treats a missed deadline as a defect.
