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.
