1. Week 1: What is a Computer? Computer Fundamentals – 4-Month Course (3 Hours per Day)

2. Day 1: Introduction — What is a Computer? Objective: Understand the definition, purpose, and role of computers. A computer is an electronic device that processes data according to a set of instructions. IPO Model: Input → Process → Output → Storage. Analogy: Computer = Kitchen Input: Ingredients → Process: Cooking → Output: Meal → Storage: Fridge Examples: ATM machines, Smartphones, Airplane navigation systems. Practice: Write about 'How computers help in my daily life'.

3. Day 2: Basic Components of a Computer Objective: Learn about hardware, software, and their relationship. Hardware: Physical components (CPU, monitor, keyboard, mouse). Software: Instructions that tell hardware what to do. Without software, hardware is useless – and vice versa. Demonstration: Identify parts like monitor, mouse, printer. Practice: Label computer parts on a diagram.

4. Day 3: The Input Stage Objective: Understand what input devices do. Input devices send data to the computer. Examples: Keyboard, Mouse, Microphone, Scanner, Camera, Touchscreen. Real-life: Typing → Keyboard, Taking photo → Camera, Scanning → Scanner. Practice: List 5 input devices used today. Quiz: Identify input vs output devices.

5. Day 4: The Processing Stage Objective: Learn how the CPU works. CPU = Brain of the computer. Main actions: Fetch, Decode, Execute. Components: ALU (calculations), CU (control), Registers (temporary storage). Analogy: Chef follows recipe – fetch, read, cook. Practice: Draw and label CPU diagram.

6. Day 5: The Output Stage Objective: Learn how computers show results to users. Output devices: Monitor, Printer, Speaker, Projector. Examples: Watching video → Monitor+Speakers, Printing receipt → Printer. Demonstration: Print a document, play audio. Practice: Identify output devices in school/home. Group: Match scenarios with correct output devices.
