IGCSE Computer Science (0478) | How Computers Represent Text, Images, and Sound!

Ever wondered how your computer displays this text, plays your favorite music, or shows you a picture of your cat? It's all just numbers to a computer! In this video, we break down how computers represent different data types – text, images, and sound – using the basic unit of binary, bits, and bytes. What we cover: Text Representation: Learn about character sets like ASCII and Unicode and how individual letters are translated into binary code. Image Representation: Discover pixels, color depth, resolution, and how computers store colors and details in a grid. We explain how higher color depths affect image quality and file size. Sound Representation: Demystify how analogue sound is converted into digital data using sampling rates and bit depth. #igcsecomputerscience #computerscience #howcomputerswork #ascii #unicode #pixels #igcsecomputerscience #computerscienceducation
