Welcome, aspiring digital architect! You're tasked with designing efficient data storage for a new multimedia application. This involves understanding how numbers, text, images, and sound are represented in binary. This quiz will test your skills in converting between number systems, calculating data sizes, and understanding data integrity concepts.
This quiz explores Data Representation, a fundamental area of the Cambridge IGCSE Computer Science (0478/0984) syllabus, primarily relevant to Paper 1. We will cover concepts from syllabus points 1.1.1 (Number systems: denary, binary, hexadecimal), 1.1.2 (Conversion between number systems), 1.2.1 (Text, sound and image representation) including ASCII and Unicode, 1.2.2 (Image representation: pixels, resolution, colour depth), 1.2.3 (Sound representation: sampling, sample rate, bit depth), 1.2.4 (Data compression: lossy and lossless), and 1.4.2 (Error detection: parity bits). Mastering these is key to understanding how computers process, store, and transmit all forms of digital information reliably.
