​Types of processor

​Very early computers could not store programs and, hence, in 1945, John von Neumann developed an idea of a computer that could store programs, which is also known as von Neumann architecture. We have learnt about this architecture in the topic ‘Computer architecture’. He suggested that data and programs could be stored in memory and that the data would be transferred between the memory and the processor during processing.
In this article, another computer architecture, Harvard architecture is introduced. The differences between von Neumann and Harvard architectures are explained.

This ​A Level Computer Science module introduces ​​​types of processor to your students, explaining:

  • ​​Issues in von Neumann architecture
  • Difference between von Neumann and Harvard architectures
  • CISC and RISC processor types
  • Coprocessor systems
