Written by leading Computer Science teachers, this textbook will guide students through the updated AQA GCSE Computer Science specification topic by topic, and provide them with standalone recap and review sections, practice questions, worked examples and clear explanations of complex topics. An algorithm is a step-by-step sequence of instructions that are used to solve a problem or complete a task. Each instruction in an algorithm must be precise enough to be understood independently. An algorithm must also clearly show the order in which instructions are carried out and where decisions are made or sections repeated.
