Von Neuman & Harvard

• What architectures are discussed in the video?

  Von Neumann, Harvard, and contemporary processor architectures
• What is the main characteristic of the classic von Neumann architecture?

  It uses a shared memory space for both instructions and data
• How does the fetch-execute cycle work in the von Neumann architecture?

  A single control unit follows a linear fetch to code execute cycle, processing one instruction at a time
• What is the purpose of registers in the von Neumann architecture?

  Registers are used for fast access to instructions and data
• How does Harvard architecture differ from von Neumann architecture?

  Harvard architecture stores instructions and data in separate memory units
• What is a characteristic of RISC processors in relation to Harvard architecture?

  RISC processors typically utilize Harvard architecture
• When did the von Neumann and Harvard architectures originate?

  In the 1940s
• What are contemporary architectures?

  Contemporary architectures are modern machine architectures that differ from older architectures like von Neumann and Harvard
• What type of questions might be asked about contemporary architectures in an exam?

  Open questions about how modern architectures differ from pure von Neumann architecture
• What does SIMD stand for?

  Single Instruction, Multiple Data
• How does SIMD processing work?

  It allows the processor to carry out a single instruction on multiple data items simultaneously
• What type of processors typically use SIMD?

  Graphic processors
• What does MIMD stand for?

  Multiple Instruction, Multiple Data
• How does MIMD processing work?

  It allows multiple instructions to be carried out on multiple data items across several different cores
• What is distributed computing?

  It involves multiple separate computers working on a shared network to tackle parts of a larger problem
• Can distributed computing be done on a larger scale, such as over the internet?

  Yes, it can be done on a much grander scale over the internet
