Computational thinking

Question 1

Procedural Abstraction

Answer 1

Using a procedure to carry out a sequence of steps for achieving some task

Question 2

Problem decomposition

Answer 2

Breaking the problem down into sub problems so that they can be solved

Question 3

Top down design (stepwise refinement)

Answer 3

A technique for breaking down a problem into the major tasks to be preformed and then breaking each task down into subtasks until each is sufficiently simple to be written as a self contained module or subroutine

Question 4

Hierarchy charts

Answer 4

Tools for representing the structure of the program showing how the modules related to each other to form a complete solution

Answer 5

Removing unnecessary details and including only the relevant details

Answer 6

Identifying the preconditions of a system, the inputs, the outputs and reusable components

Question 7

Answer 7

Breaking a problem down

Question 8
