Computing Systems and Responsible Use

Learners read a resource-monitor snapshot to find out what is really using a computer's processor and memory, explain why security patches matter and plan a sensible update routine, apply least privilege with standard and administrator accounts and an acceptable-use policy, and weigh a device's lifecycle, energy use and e-waste options. Shared computers at a fictional town library and high school run through the whole course.

What learners will discover

  • Read a resource-monitor snapshot to identify which processes are using processor time and memory, and choose a reasonable response to a slow system.
  • Explain how updates and security patches reduce risk, order the patch lifecycle, and plan an update routine that accounts for end of support.
  • Distinguish standard and administrator accounts, apply least privilege, and interpret an acceptable-use policy for shared systems.
  • Evaluate a device's lifecycle, estimate its energy use, and recommend responsible choices for repair, reuse and e-waste.
