Lesson Plan

• Describe the role of utility software in extending core OS services.
• Identify at least five common utility programs and state their primary functions.
• Explain how utilities improve system reliability, efficiency, and security.
• Compare utility software with general‑purpose application software, highlighting key differences.
• Evaluate scenarios where specific utilities (e.g., backup, antivirus) are essential for system upkeep.

• Projector and screen
• Slide deck summarising utility types
• Printed handout of the utility table
• Computers with Windows/macOS/Linux installed
• Worksheet for guided exploration
• Whiteboard and markers
• Exit‑ticket slips

Begin with a quick poll: “Which tools on your computer do you use to keep it running smoothly?” Connect responses to prior knowledge of OS basics, then state that today’s success criteria are to name key utilities, explain their purposes, and link them to system reliability.

1. Do‑Now (5 min): Students write three utilities they have used and why.
2. Mini‑lecture (10 min): Present why utilities are needed, using the provided slide and handout.
3. Guided Exploration (15 min): In pairs, students open File Manager, Disk Cleanup, and Task Manager on lab PCs, noting functions on the worksheet.
4. Concept‑Mapping Activity (10 min): Groups create a visual map linking utilities to reliability, security, and efficiency.
5. Comparison Discussion (10 min): Whole‑class dialogue contrasting utility software with application software.
6. Quick Quiz / Exit Ticket (5 min): Each student lists three utilities and describes one way each supports system reliability.

Recap the main utilities covered and how they safeguard the OS. Collect exit tickets as a retrieval check, and assign a homework task: research one additional utility not discussed (e.g., system monitor, driver updater) and write a short paragraph on its purpose and importance.
