In the Von Neumann Architecture, what is the role of the arithmetic logic unit?

• It controls the input and output mechanisms.

• It stores the data and instructions.

• It performs arithmetic and logical operations.

• It manages the external data storage.

What does the CPU do during the fetch step?

• It performs calculations with the data.

• It stores data and instructions in the main memory (RAM).

• It fetches data and instructions from the main memory (RAM) and stores them in registers.

• It sends data to the output devices.

Where does the CPU store data and instructions temporarily during the fetch step?

• In the hard drive

• In the registers

• In the cache memory

• In the main memory (RAM)

What hardware path does the CPU use to put the memory address of the next item it wants onto?

• Data bus

• Control bus

• Address bus

• USB

Which hardware path is used for data to travel from the RAM to the CPU?

• USB

• Address bus

• Control bus

• Data bus

What does the decode step in a CPU involve?

• Executing the instruction

• Fetching the instruction from memory

• Working out what the fetched instruction means

• Performing arithmetic and logical operations

Which unit of the CPU decodes the instruction and prepares for the next step?

• Arithmetic logic unit

• Memory unit
