0:00 - Intro
0:30 - The need for compression
3:50 - How it works (Lossy vs Lossless)
5:58 - Lossy Compression
8:10 - Lossless Compression (Run Length Encoding)
12:05 - Common file types
13:00 - Practice Questions

🔹 Topics Covered:
✅ Different file types and their purposes
✅ Lossy vs. lossless compression – What’s the difference?
✅ How compression techniques reduce file size
✅ The trade-offs between quality and storage efficiency

📚 Perfect for:
✔️ iGCSE Computer Science students
