Understanding CPU and ALU Functions

Which of the following best describes the main function of the CPU in a computer system?

• To store data permanently

• To process instructions and manage operations

• To display images on the monitor

• To provide power to the computer

What does ALU stand for in the context of computer architecture?

• Arithmetic Logic Unit

• Advanced Logic Utility

• Automated Learning Unit

• Analogue Logic Unit

Which component temporarily holds data that is being transferred to or from the memory?

• MAR

• MDR

• ALU

• FDR

What is the primary role of the ALU within the CPU?

• To store instructions

• To perform arithmetic and logical operations

• To manage input and output devices

• To control the flow of data

Which register holds the address of the memory location to be accessed?

• MDR

• MAR

• FDR

• ALU

The MDR is responsible for:

• Storing the next instruction to be executed

• Holding data that is being transferred to or from memory

• Performing calculations

• Managing the clock speed

Which of the following is NOT a function of the ALU?

• Addition

• Subtraction

• Data storage

• Logical comparison

In the fetch-decode-execute cycle, which register is used to fetch the instruction from memory?

• MAR

• MDR

• ALU

• FDR

What does FDR most likely stand for in the context of CPU architecture?

• Fast Data Register

• Fetch Data Register

• File Data Register

• Function Data Register

Which of the following operations can the ALU perform?

• Multiplication

• Data transfer to hard drive

• Displaying graphics

• Managing network connections
