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.

You will:

  • Explore 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
  • Explore how computers use binary arithmetic
  • Explore how logic gates can be combined to produce digital circuits that can perform a calculation
  • Investigate Von Neuman Architecture and the Fetch-Execute cycle
