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?

What is a set of step-by-step instructions to solve a task called?

It ensures the instructions are written in Python.

It makes the algorithm executable by a computer.

It replaces the need for programming languages.

It is written in a specific programming language.

What makes a computer program different from an algorithm?

Algorithms are general, while computer programs are specific.

What is another key difference between an algorithm and a computer program?

a systematic approach to solving problems

Which computational thinking technique focuses on important details and ignores irrelevant ones?

Which computational thinking technique involves breaking a problem into smaller, manageable parts?

Which computational thinking technique involves creating logical, step-by-step instructions?
