2. Levels of Abstraction
  • Still hardware
  • At a component (subsystem) level
    • transistors -->gates -->circuits
    • circuits -->subsystems
  • Abstraction hides detail
    • important concept in my areas of CS



































CSCI N301 Fundamental CS Concepts: Organization
3. Von Neumann architecture
  • Four major subsystems
    • memory
    • input/output (I/O)
    • arithmetic-logic unit (ALU)
    • control unit
  • Stored program concept
  • Sequential fetch-execute cycle
