# Free Online Course on How Computers Work: Demystifying Computation

Explore the fundamentals of computing: computer architecture, binary logic, data processing, circuits & more. Supported by Google.

## Understand computation, the basis of every computer system

In 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.

## What topics will you cover?

- 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

## Who is the course for?

This course would suit KS3 and GCSE Computer Science teachers – plus educators from other countries that teach at an equivalent level.
