🎯 Learning Intention

I will describe how information moves through a computer system and explain how each major component contributes to that process.

✅ Success Criteria

• I can name and define the core components of a computer.
• I can explain the IPOS model (Input → Processing → Output → Storage).
• I can connect each component to its function in real-world systems.

🌍 Why We’re Learning This

Understanding how hardware communicates is the foundation of all IT work.

Every certification, from Tech+ to A+, builds on your ability to visualize how data travels through a system.

⏰ Warm-Up (10 min)

“If data were water, where would it start, flow through, and end inside a computer?”

Write or sketch your answer in your Tech Journal. Label at least three components (CPU, RAM, Storage, Bus).

🧠 Mini-Lesson (20 min) — Inside the Machine

1. Quick visual walkthrough: motherboard as the nervous system.
2. Review each part’s function:
   • CPU — Executes instructions (“the brain”).
   • RAM — Short-term memory for quick access.
   • Storage — Long-term data holding (SSD/HDD).
   • Bus — High-speed highway for digital signals.
   • Power Supply — Converts AC → DC.
3. Discuss how IPOS connects them:
   • Input (keyboard/mouse) → Processing (CPU + RAM) → Output (monitor) → Storage (SSD).

• Bit = binary digit (0 or 1)
