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.
Computers are simply electronic machines that carry out instructions given by human programmers; although a computer can solve many complex problems, it can only do so if it is given instructions to tell it how to do so. Writing these instructions in a form that is suitable for a computer to carry out can be a challenging task! 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.
This textbook:
- Prepares students for assessment with numerous practice questions for all topics
- Develops computational thinking skills
- Provides differentiated material with the ''beyond the spec'' feature
- Includes standalone recap and review sections at the end of each chapter
- Provides definitions of technical terms, along with a glossary of words to ensure students feel confident with the assessment.
