Unit 2 - Abstraction and Automation

Which of the following is not done by abstraction?

• Identifies essential details

• Disregards non-essential information

• Breaks the problem down into smaller tasks

Which of the following is not done by decomposition?

• Allows multiple people to work on the problem together

• Disregards non-essential information

• Breaks the problem down into smaller tasks

When drawing a dog, which of the following characteristics is non-essential?

• Dogs have 4 paws

• Dogs have fur

• Dogs can have brown fur

When designing a building that must be accessible for wheelchairs, which of the following characteristics is non-essential?

• Number of doors

• Number of walls

• Number of wall paintings

You could use abstraction to replace specific objects with simple shapes

• True

• False

Abstraction and Decomposition are examples of...

• Computational Thinking

• Algorithmic Thinking

• Computer Science

• Logical Reasoning

Why do we decompose a complex problem?

• To make it easier to solve

• To make it more difficult to solve

• To change the problem we have

What is pattern recognition?

• Breaking down a complex problem into smaller problems

• Looking for similarities among and within problems

• Building models from patterns

Why do we need to look for patterns in problems?

• Patterns make it easier for us to solve complex problems

• We don't need to look for patterns

• Patterns make it more difficult complex problems

What is automation?

• Modelling of real-world problems

• Breaking a problem down in to smaller chunks

• removing unnecessary detail

• Information hiding
