Data is AI's Brain Food! 🍕

What Even IS Data?

Data is any information stored on a computer. It's EVERYTHING:

| Type | Examples | |------|---------| | 📸 Images | Your selfies, dog photos, memes | | 📝 Text | Messages, tweets, book pages | | 🔢 Numbers | Scores, temperatures, prices | | 🎵 Audio | Songs, voice messages, podcasts | | 🎥 Video | YouTube clips, TikToks, film | | 📍 Location | Where your phone is right now | | 🖱️ Behaviour | What you click, how long you watch |

🤖 Why AI NEEDS Data

Think of it this way:

Teaching a baby to say "dog" 🐕: Show photo: "dog!" ×1 Show photo: "dog!" ×10 Show photo: "dog!" ×100 → Baby starts recognising dogs! Teaching AI to recognise dogs: Show photo: "dog" ×1,000 Show photo: "dog" ×100,000 Show photo: "dog" ×10,000,000 → AI gets REALLY good at spotting dogs!

The more examples, the smarter the AI gets. No data = no learning!

📊 How Much Data Exists?

• Every minute, we create 2.5 quintillion bytes of data (that's 2,500,000,000,000,000,000 bytes! 🤯)
• 95 million photos uploaded to Instagram every day
• 500 hours of video uploaded to YouTube every MINUTE
• Your TikTok creates data every second: what you watch, skip, rewatch, and share

🎮 Data You Create Without Knowing

When you use Roblox:

• How long you played each game
• Which items you clicked
• Where you went in the world
• Which other players you interacted with

That's data! Roblox uses it to suggest games you'll enjoy.

💡 Two Types of Data

Structured data: Neatly organised in rows and columns, like a spreadsheet

• Your score history: [100, 85, 72, 95, ...]

Unstructured data: Messy, free-form — harder for AI but more common

• Chat messages, photos, videos, audio
