• Charles Babbage

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

• To execute instructions

• To hold the results of calculations

• To help control instructions and data around the CPU

• To store large amounts of data

What does the program counter hold in a von Neumann architecture?

• The contents of the cache

• The results of calculations

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

• The address of the next instruction to be executed

What is the function of the memory data register in the CPU?

• To hold any data fetched from memory or to be written to memory

• To hold the results of calculations

• To hold the address of the next instruction to be executed

• To store large amounts of data

What is the role of the accumulator in the von Neumann architecture?

• To help control instructions and data around the CPU

• To hold the address of the next instruction to be executed

• To hold the results of calculations

• To store large amounts of data

What is the main characteristic of the von Neumann architecture?

• It has no internal clock

• It has a central processing unit with multiple arithmetic logic units

• It has multiple control units

• It has a single control unit and an arithmetic logic unit

What is the purpose of the internal clock in a von Neumann architecture?

• To help control instructions and data around the CPU

• To store large amounts of data

• To hold the address of the next instruction to be executed

• To provide a pulse at a constant rate to synchronize components

What is the function of the memory address register in the CPU?

• To hold the address of the next instruction to be executed

• To help control instructions and data around the CPU

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

• To hold the results of calculations

What is the role of the control unit in a von Neumann architecture?

• To hold the address of the next instruction to be executed

• To decode the instruction and execute it

• To store large amounts of data

• To help control instructions and data around the CPU

What is the stored-program concept in a von Neumann architecture?

• Instructions data and program data are stored in separate memory units

• Instructions data and program data are stored in the same memory in binary form

• The architecture does not support changeable programs

• There is no memory in the architecture
