Von Neumann

• What are the main components of the CPU?

  Arithmetic Logic Unit (ALU), Control Unit (CU), and Registers.
• What are all the components of Von Neumann Architecture?

  The Control Unit, the Arithmetic Logic Unit, Registers, internal/main memory, input/output devices, buses, Random Access Memory
• What are the names of the three buses?

  Address, Control, Data
• What is the role of the Arithmetic Logic Unit?

  Performing arithmetic and logical operations.
• What is the role of the Control Unit?

  To execute machine code by sending control signals via the Control Bus, and to perform the fetch-decode-execute cycle in sync with the internal clock.
• What are the Registers?

  Small, dedicated blocks of data typically used to store instructions being processed.
• What is the role of the Address Bus?

  To carry memory addresses from the CPU to either memory or the I/O controller.
• Which way does the Address Bus move?

  Unidirectionally
• What is the role of the Data Bus?

  Send data between the processor and I/O devices.
• Which way does the Data Bus move?

  Bidirectionally
• What is the role of the Control Bus?

  Carry signals from the processor to control memory and I/O devices.
• Which way does the Control Bus move?

  Bidirectionally
