COMPUTER SCIENCE GCSE/IGCSE- summarized paper 1 revision notes
This Grade 9/A* Data Representation master pack covers the essentials of how computers store and process information. It features step-by-step guides for Binary, Denary, and Hexadecimal conversions, alongside clear methods for Two’s Complement and Logical Shifts (multiplication and division). The guide also provides detailed breakdowns of Bitmap Images (pixels, color depth, and resolution), Sound Representation (sampling rate and bit depth), and ASCII vs. Unicode. With worked examples for File Size Calculations and a comparison of Lossy vs. Lossless Compression, these notes are the perfect tool to master the math-heavy side of Computer Science and secure top marks in your exams.
