Understanding Abstraction and Decomposition

What is the main challenge when trying to get the most out of computers?

• Computers are too expensive.

• Computers don't understand which details are important.

• Computers are too slow.

• Computers are too large.

What is the term used to describe the process of getting a computer to focus on the essentials?

• Decomposition

• Abstraction

• Compilation

• Simulation

In the context of forming a dance group, which detail is NOT important according to the concept of abstraction?

• Willingness to dance

• Ability to dance

• Colour of their hair

• Enthusiasm

What is decomposition in computational thinking?

• Combining tasks into a larger task

• Breaking down a problem into smaller, simpler parts

• Ignoring unnecessary details

• Enhancing computer speed

Why is it important to decompose a task for a computer?

• To make the task more complex

• To ensure the computer can understand and process it

• To make the task more expensive

• To make the task more time-consuming

What is an example of a simple task that can be decomposed for a computer?

• Writing a novel

• Shopping

• Building a house

• Painting a picture

When decomposing the task of shopping, which of the following is NOT a smaller task?

• Making a shopping list

• Driving to the shop

• Buying items

• Writing a computer program

What is the first step in decomposing a task for a computer?

• Ignoring the task

• Breaking it down into smaller tasks

• Asking someone else to do it

• Completing the task manually

Why can't computers think for themselves?

• They are too expensive

• They require clear instructions

• They are too slow

• They are too large

What is the benefit of using abstraction in computational thinking?

• It makes tasks more complicated

• It helps focus on important details

• It increases the cost of tasks

• It makes tasks slower
