Von Neumann Architecture Quiz

Who invented the Von Neumann architecture?

• Alan Turing

• John von Neumann

• Ada Lovelace

• Charles Babbage

What is the main function of the ALU in the Von Neumann architecture?

• Store data

• Fetch instructions

• Execute instructions

• Perform arithmetic and logic operations

In Von Neumann architecture, where are data and instructions stored?

• Secondary memory

• External storage

• Cache memory

• Primary memory

What does the program counter (PC) hold?

• The data being processed

• The memory address of the next instruction

• The address of the current instruction

• The current instruction being executed

Which register holds the address of the current instruction to be fetched?

• Accumulator (ACC)

• Memory Data Register (MDR)

• Memory Address Register (MAR)

• Current Instruction Register (CIR)

What is the stored program concept?

• Using multiple processors

• Executing multiple instructions simultaneously

• Storing a program in memory as instructions

• Storing data in secondary memory

What is the function of the Memory Data Register (MDR)?

• Holds the current instruction being executed

• Holds the contents found at the address held in the MAR

• Holds the data being processed

• Holds the address of the next instruction

Which register holds the instruction that is currently being decoded and executed?

• Current Instruction Register (CIR)

• Accumulator (ACC)

• Memory Address Register (MAR)

• Program Counter (PC)

What is the role of the accumulator (ACC) in the Von Neumann architecture?

• Holds the data being processed and the results of processing

• Holds the current instruction being executed

• Holds the contents found at the address held in the MAR

• Holds the memory address of the next instruction

What is the fetch-decode-execute cycle?

• A method to store data

• A technique to increase memory capacity

• A process to execute instructions sequentially

• A way to connect multiple processors
