1.1.1 Revision Starter Quiz - Architecture of the CPU

Which of the following components is not part of the CPU architecture?

• Arithmetic Logic Unit (ALU)

• Control Unit (CU)

• Main Memory

• Register

Which of the following best describes the role of the clock in a CPU?

• To control the speed at which instructions are executed

• To store temporary data

• To manage input and output operations

• To connect the CPU with external devices

What happens during the 'decode' stage of the Fetch-Decode-Execute cycle?

• The CPU retrieves the instruction from memory

• The instruction is interpreted and prepared for execution

• The CPU performs the actual operation of the instruction

• The result of the instruction is stored in memory

The Control Unit (CU) is responsible for:

• Performing calculations

• Storing data

• Coordinating the activities of the CPU

• Managing input/output devices

In the CPU, what is the function of a register?

• To permanently store data and instructions

• To hold data temporarily during processing

• To manage communication between the CPU and peripheral devices

• To store the boot instructions of the computer

Which register holds the address of the next instruction to be executed?

• Memory Address Register (MAR)

• Memory Data Register (MDR)

• Program Counter (PC)

• Accumulator

What is the primary function of the Arithmetic Logic Unit (ALU)?

• To fetch instructions from memory

• To perform arithmetic and logic operations

• To control the flow of data within the CPU

• To store data temporarily

What does CPU stand for?

• Central Programming Unit

• Central Processing Unit

• Central Performance Unit

• Central Peripheral Unit

What is the purpose of the Memory Address Register (MAR)?

• To hold the data being transferred to and from the memory

• To store the current instruction being executed

• To store the result of arithmetic operations

• To hold the address of the memory location to be accessed

Which cycle involves fetching an instruction from memory, decoding it, and executing it?

• Machine Cycle

• Fetch-Execute Cycle

• Fetch-Decode-Execute Cycle

• Instruction Cycle
