CHAPTER 3 CPU final quiz

What component in the Von Neumann Architecture holds the next instruction's memory address?

• MDR

• MAR

• ALU

• CU

What does the Control Unit (CU) do?

• Performs calculations

• Manages data flow inside the CPU

• Stores data permanently

• Executes only multiplication operations

Which CPU component is responsible for performing arithmetic and logic operations?

• CU

• ALU

• MDR

• PC

What is the primary function of registers in a CPU?

• Store frequently accessed data

• Store permanent files

• Connect to the internet

• Control external devices

The purpose of the Program Counter (PC) is to:

• Store the result of a calculation

• Hold the memory address of the next instruction

• Store instructions that need to be executed later

• Increase the CPU speed

What is the first step in the Fetch-Decode-Execute cycle?

• Fetching the instruction from memory

• Decoding the instruction

• Executing the instruction

• Sending results to output devices

What happens during the Decode stage of the cycle?

• The CPU retrieves the instruction from RAM

• The CPU translates the instruction into a form it can execute

• The instruction is sent to the ALU

• The output is displayed on a monitor

Which register temporarily holds data that is being transferred between the CPU and memory?

• MAR

• MDR

• IR

• PC

Increasing a CPU's clock speed results in:

• Slower processing speed

• Higher processing speed

• More storage space

• Less heat generation

Which unit is used to measure CPU clock speed?

• Hertz (Hz)

• Bytes (B)

• Gigabytes (GB)

• Celsius (°C)
