What does this lesson cover?
Students often mix up a device's brand with its operating system, or think one system is best for everyone. This lesson teaches them to choose a system by what the user needs to do. The history shows that each change added a new way to use a computer, and that people still use the old ways for some jobs.
Pick the System
Students read about four users, then log what each one needs, the kind of operating system that fits and why.
