Questions and Answers

What is a characteristic of the Von Neumann computer architecture?

  • Instructions and Data are physically separated
  • It has separate buses for instructions and data
  • It is primarily used in microcontrollers and signal processing
  • Instructions and Data are stored in the same memory (correct)

    • Which statement is true about the Harvard computer architecture?

  • The bit width of Data is generally wider than that of Instructions (correct)
  • It is primarily used in PC, laptops, and workstations
  • It has only one bus for both instructions and data
  • The Instruction memory is read-only in all cases

    • What is the instruction set in a computer related to?

  • Native data types (correct)
  • External I/O operations only
