3 J277 1.1 Von Neumann Architecture Quiz

What is a key characteristic of the von Neumann architecture?

• It has multiple control units.

• It has a central processing unit with a single control unit.

• It does not use an arithmetic logic unit.

• It does not use on-board cache.

What is the function of the arithmetic logic unit (ALU) in the von Neumann architecture?

• To store data permanently.

• To control the flow of data around the CPU.

• To perform arithmetic and logical operations.

• To provide a pulse at a constant rate.

What is the purpose of the on-board cache in the von Neumann architecture?

• To store data permanently.

• To provide a pulse at a constant rate.

• To help control the instructions and data around the CPU.

• To decode instructions.

What does the internal clock in the von Neumann architecture do?

• It stores data permanently.

• It provides a pulse at a constant rate to synchronize components.

• It controls the flow of data around the CPU.

• It performs arithmetic and logical operations.

What is a stored-program computer?

• A computer with fixed programs that cannot be changed.

• A computer that requires rewiring to change programs.

• A computer with changeable programs.

• A computer that does not use a CPU.

Who described the first design for modern computers with stored programs?

• Alan Turing

• Charles Babbage

• Jon von Neumann

• Ada Lovelace

Which register always holds the memory address of the next instruction to be executed?

• Memory address register

• Memory data register

• Program counter

• Accumulator

What does the memory address register hold?

• The results of calculations performed by the arithmetic logic unit

• The address of where data is to be fetched from or stored into

• The memory address of the next instruction to be executed

• Any data which has been fetched from memory or is about to be written to memory

What is the role of the memory data register?

• Holds the address of the next instruction to be executed

• Holds the address of where data is to be fetched from or stored into

• Holds any data which has been fetched from memory or is about to be written to memory

• Holds the results of calculations performed by the arithmetic logic unit

What does the accumulator hold?

• The address of the next instruction to be executed

• The address of where data is to be fetched from or stored into

• Any data which has been fetched from memory or is about to be written to memory

• The results of calculations performed by the arithmetic logic unit
