12.01 - What is Computational thinking?

Question 1

What is computational thinking?

Answer 1

It is a problem solving process where a number of steps are taken in order to reach a solution

Question 2

What are the 5 key strands of computational thinking?

Answer 2

1. Abstraction
2. Decomposition
3. Data modelling
4. Pattern recognition
5. Alogorithmic thinking

Question 3

What is Abstraction?

Answer 3

It involves filtering out information that is not nessasary to solve a problem. It gives the power to deal with complexity

Question 4

What is an algorithm in terms of abstraction?

Answer 4

An algorithm is an abstraction of a process that takes inputs, executes a sequence of steps and produces an output

Question 5

What does an abstract data type define?

Answer 5

It defines an abstract set of values and operations to manipulate those values

Question 6

What is Decomposition?

Answer 6

It means breaking down problems into sub-problems in order to explain a process more clearly. it lead us to the concept of program modules and using procedures and functions

Question 7

What is data modelling?

Answer 7

It involves analysing and organising data. We can step up abstract data types to model real world concepts such as stacks and queues.

Question 8

What happens if a programming language doesnot have abstract data types built in to model real world concepts?

Answer 8

Then we can define our own by buliding them from existing data types

Question 9

What is pattern recognition?

Answer 9

It means looking for patterns and common solutions to common problems and using these to complete tasks in a more efficient and effective way

Question 10

What is an algorithm design?

Answer 10

It involves developing step by step instructions to solve a problem.
