💡 The Big Picture:A computer is an electronic system that takes raw data as Input, processes it under programmed logic, and produces meaningful Information as Output.
🍪 Everyday Analogy:Think of baking cookies: Flour & Sugar (Input) ➔ The Oven (Processing) ➔ Warm Delicious Cookie (Output)! 🍪
Key Exam Takeaways
  • ·Data = Raw, unprocessed facts without context (e.g. 42, 'apple').
  • ·Information = Structured data with meaning (e.g. 'Temperature: 42°C').
  • ·Hardware is what you can touch; Software is the instructions running inside.
