Study Notes
Abstraction in Computer Science
- An example of abstraction is showing essential features of an object or system while hiding irrelevant details.
- The purpose of abstraction in problem-solving is to simplify complex problems by breaking them down into manageable parts, focusing on essential features, and ignoring irrelevant details.
Principles of Computational Thinking
- The three principles of computational thinking are decomposition, abstraction, and pattern recognition.
- NOT one of the three principles of computational thinking is iteration.
Abstraction in Computational Thinking
- Abstraction in the context of computational thinking means identifying the essential features of a problem or system while ignoring irrelevant details.
Importance of Abstraction at GCSE Level
- It is important to be aware of abstraction at GCSE level because it helps to simplify complex problems, making it easier to understand and solve them.
