2.1.1 Computational thinking

Abstraction

Abstraction

• ignoring any unnecessary inormation and only focusing on important facts

• used because it simplifies a problem to make it less complex

• its more straighforward to understand the problem and creae a solution

decomposition

• breaking down a problem into smaller parts so that it’s easier to solve

• each individidual problem can be separately tested and solved

• decomposition enables different people to work on the different parts of a larger problem that can later be recombined to produce a full solution

algorithmic thinking

• the final stage as logical steps are followed to solve the problem

• the problem is broken down using decomposition into smaller problems

• the required data and relvant data structures are considered during abstraction

what is an algorithm?

• a set of instructions in a logical sequence for solving a problem or completing a task

• programmers create algorithm designs as a method of planning a program
