How Computers Work: Demystifying Computation

CO206 Online course

Explore the fundamentals of computing - computer architecture, binary logic, data processing, circuits, and more.

Computing Mathematics Key stage 3 Key stage 4 CS Accelerator

Free online course Approximately 8 hours of self-study

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.

Who is it for?

This course is aimed at classroom teachers teaching up to and including GCSE computer science.

Topics covered

You'll cover the following topics:

How computers use binary arithmetic
How transistors can act as digital switches and be combined to create logic gates
Creating truth tables for AND, NOT and OR gates, individually or combined
How logic gates can be combined to produce digital circuits that can perform a calculation
Von Neuman Architecture and the Fetch-Execute cycle
