What is one purpose of the CPU?

• Define a set of characters the computer understands
• Optimise a set of instructions
• Prevent phishing
• Execute instructions

Which of these describes a classic von Neumann architecture?

• Data transfers and instruction fetches from memory can be done at the same time
• Uses separate memory addresses for instructions and data
• Control unit is more complicated to handle separate instruction and data buses
• The processor needs more than one cycle to fetch, decode and execute an instruction

Which of these describes a classic von Neumann architecture?

• Has an instruction bus and a data bus for the transfer of instructions and data between the CPU and RAM
• Has an address bus and a data bus that can be used to transfer instructions and data between the CPU and RAM
• Has one data bus for the transfer of instructions and data between the CPU and RAM
• Has two data buses for the transfer of instructions and data between the CPU and RAM

Which of these describes a classic von Neumann architecture?

• Data transfers and instruction fetches between memory can be done at the same time
• Uses a separate memory address for instructions and data
• Processor needs one cycle to complete an instruction
• Uses the same physical memory address for instructions and data

Which of these describes a classic von Neumann architecture?

• The processor only requires one cycle to complete an instruction
• Data transfers and instruction fetches from RAM cannot be performed at the same time
• Uses separate memory address space for instructions and data
• Data transfers and instruction fetches can be performed at the same time

The address of an instruction or data pointed at by the memory address register is sent to which register during a fetch operation?

• Accumulator
• Memory address register
• Program counter
• Memory data register

Which computer architecture holds both programs and data in same main memory?

• To perform calculations in the CPU
• Control the loading of data from the hard disk to RAM
• To control peripherals using device drivers
