CPU and Memory Components Quiz

What is the primary function of the Address Bus?

• To carry command and status signals between the CPU and other components.

• To carry the actual data being transferred.

• To specify the memory location the CPU wants to communicate with.

• To store the results of calculations.

Which component manages the fetch-decode-execute cycle?

• Arithmetic Logic Unit (ALU)

• Control Unit (CU)

• Memory Address Register (MAR)

• Random Access Memory (RAM)

During which stage of the Fetch-Decode-Execute cycle is the instruction interpreted?

• Fetch Stage

• Decode Stage

• Execute Stage

• Storage Stage

What does the Memory Data Register (MDR) temporarily store?

• Only memory addresses.

• Only control signals.

• Data or an instruction fetched from memory or waiting to be written to memory.

• The final results of all computations.

Which part of the CPU performs calculations and logical operations?

• Control Unit (CU)

• Arithmetic Logic Unit (ALU)

• Program Counter (PC)

• Current Instruction Register (CIR)

What is the role of the Accumulator (ACC)?

• To hold the address of the next instruction.

• To store the current instruction being executed.

• To temporarily store data, or the results of arithmetic and logical operations.

• To manage the flow of data on the data bus.

In the Fetch Stage, where is the address from the Program Counter (PC) copied to?

• Current Instruction Register (CIR)

• Memory Address Register (MAR)

• Accumulator (ACC)

• Memory Data Register (MDR)

What happens to the Program Counter (PC) after an instruction is fetched?

• It is cleared.

• It is copied to the CIR.

• It is incremented.

• It receives data from the ALU.

What type of memory is RAM (Random Access Memory) an example of?

• Non-Volatile Memory

• Volatile Memory

• Read-Only Memory

• Secondary Storage

Which of the following is an example of Non-Volatile Memory?

• CPU Registers

• Cache Memory

• Hard Disk Drives (HDD)

• System Bus
