Intro

Question 1

What is computational thinking?

Answer 1

thought processes involved in formulating problems and their solutions, so that solutions are in a form that can be effectively carried out by an information-processing agent

Question 2

What is an algorithm?

Answer 2

precise systematic method for producing a specified result

Question 3

Algorithms describe a sequence of steps that are… (3)

Answer 3

unambiguous

• no ‘assumptions’ are required to execute the algorithm
• algorithm uses precise instructions

executable
- algorithm can be carried out in practice

terminating
- algorithm will eventually come to an end, or halt

Question 4

What are the 3 key CT building blocks?

Answer 4

decomposition
abstraction
synthesis

Question 5

What is decomposition?

Answer 5

take a complex problem and break it into smaller problems that you can solve

Question 6

What is abstraction?

Answer 6

used in defining patterns, generalizing from instances, and parameterization, and used to let one object stand for many - describing the solution in a general way

**(most important and high-level thought process in computational thinking)

Question 7

What is synthesis?

Answer 7

process of combining partial solutions together to solve a problem
