Computer Science

a set of step-by-step instructions to solve a problem

a way of implementing an algorithm by writing it in a language that a computer can use

a system of rules that determine the flow of instructions

Comparing algorithms to computer programs

In this unit pupils will discover the computational thinking techniques; decomposition, abstraction and algorithmic thinking. They will reflect on differences between algorithms and computer programs and explore how algorithms can be represented. Pupils will explore the impact of algorithmic bias.

Algorithms

a set of step-by-step instructions to solve a task

instructions written in a programming language

a Python program to calculate the area of a circle

a set of rules for a programming language

Which of the following is an example of an algorithm?
