How Computers Work: Demystifying Computation
Understand computation, the basis of every computer system
On this course, you’ll gain an understanding of how computers work at a fundamental level.
You’ll explore system architecture, along with how computers use binary and logic. Once you’ve examined the von Neumann model of computer architecture and the Fetch-Execute cycle, you’ll learn to build a range of simple circuits for maths, and then simulate various logic gates.
Ultimately you’ll complete the course with an understanding of the processes that underpin every modern computer – from supercomputers to smartphones, and everything in between.
Syllabus
Week 1
What is a computer anyway?
Introduction
An introduction to the course, the education team and your fellow learners.
What is a computer?
What do we mean by the word 'computer', and how has that meaning changed over the years?
How computers count
An introduction to binary mathematics and switches.
Week 2
Logic Gates
Welcome to Week 2
An introduction to what you will be learning in Week 2
NAND gates
How transistors can be used to create NAND gates
All the gates
A brief overview of all the other logic gates
Combinational Logic Circuits
This section will cover how logic gates can be combined to perform unique operations
Week 3
Mathematics with circuits
Binary mathematics
An introduction to addition and multiplication of binary numbers.
Binary multiplication
Another important mathematical function that may need to be performed inside a computer is multiplication. Learn how multiplication works in binary.
Maths with logic gates
How does a computer use logic gates in order to perform mathematics in binary?
Week 4

What will you achieve?
By the end of the course, you‘ll be able to...
- Explain how transistors can act as digital switches and be combined to create logic gates
- Produce truth tables for AND, NOT and OR gates, individually or combined
- Explain how computers use binary arithmetic
- Describe how logic gates can be combined to produce digital circuits that can perform a calculation
- Describe Von Neuman Architecture and the Fetch-Execute cycle
Who is the course for?
This course would suit teachers of KS3 and GCSE Computer Science - plus educators from other countries that teach at an equivalent level.
What do people say about this course?
I enjoyed the course, even the really challenging part about logic gates in the middle. I'm undertaking the CAS for teachers and this really helped join some parts of my learning together.
