Abstraction Quiz

What is abstraction?

• The process of removing unnecessary details and including only the relevant details

• The process of adding unnecessary details and excluding relevant details

• The process of storing data in a specific format

• The process of designing user interfaces

Consider you are using a sat-nav system while driving. Which of the following features of the system is an example of abstraction in user interface design?

• The system displays your car's location and the road layout

• The system includes representations of buildings and trees

• The system has additional icons for volume, time, battery life, etc.

• The system uses abstract data structures for its display

Why would a designer use icons in the layout of a mobile app?

• To suggest a function or process in a clear, efficient way

• To represent buildings and trees in a sat-nav display

• To store data in a specific format

• To manipulate data programmatically

How can data structures be abstracted in a GPS navigation app like Google Maps?

• By manipulating the data programmatically instead of storing it in a specific format

• By including realistic maps with a sensible scale of distances

• By including additional icons for volume, time, battery life, etc.

• By including buildings and trees in the display output

Why would a software developer use a flowchart when designing a new app?

• To provide a visual representation of the app's functionality before writing any code

• To store user data in a specific format within the app

• To manipulate user data within the app

• To represent buildings and trees in the app's map feature

Imagine you are a postman and you have to deliver letters to different houses. How would you describe variables in programming in this context?

• They are like the house addresses, serving as labels for memory locations where data (letters) are stored

• They are like the letters themselves, serving as abstract data structures

• They are like the postman's uniform, serving as icons used in user interfaces

• They are like the postal codes, serving as binary numbers assigned to data

John has 10 apples (b). He gives 3 apples (c) to his friend. How many apples (a) does John have now? This can be represented as 'a = b - c' in programming. What does this represent?

• A calculation involving variables

• A process of removing unnecessary details

• A method of computational thinking

• A representation of buildings and trees in a sat-nav display

Why would you use a sat-nav app while driving in an unfamiliar city?

• To help you navigate and find specific locations

• To store data about the city in a specific format

• To manipulate data about the city programmatically

• To represent buildings and trees in the city on a display

When designing a new car, what is the main focus of abstraction in problem solving?

• Considering only the relevant details such as engine performance and safety features

• Including unnecessary details such as the color of the designer's pen

• Storing data in a specific format such as the designer's notebook

• Designing user interfaces such as the car's dashboard
