2. AQA GCSE (8525) SLR1 – 3.4 Von Neumann architecture
About this video
AQA Specification Reference - Section 3.4
This video explores the first computers that had stored programs in the same memory space as the data required for them. This is known as the von Neumann architecture and is still the foundation principle on which most computers are still built today. We take the lid off a central processing unit and explain the key components including the ALU, clock, busses and the control unit.
Don't forget, whenever the blue note icon appears in the corner of the screen, that is your cue to take notes about the content being shown on the current slide.
