OCR GCSE (J277) 2.1 Abstraction Quiz

What is abstraction?

• Hiding essential features from users

• Representation of essential features without including unnecessary details

• Making systems more complex for users

• Including unnecessary details in the representation

What is the purpose of abstraction?

• To reduce the complexity of systems for users

• To increase the complexity of systems for users

• To apply algorithms to different contexts

• To confuse users about how things work

How does abstraction hide the complexity of systems?

• By representing essential features without including unnecessary details

• By making systems more complex for users

• By confusing users about how things work

• By including unnecessary details
