Understanding the CPU and Its Components

What is the primary function of the central processing unit (CPU)?

• To provide power to computer components

• To store large amounts of data

• To manage and process all computer operations

• To output data to external devices

What are registers within a CPU primarily used for?

• Storing temporary data and addresses

• Enhancing graphics processing

• Saving permanent user data

• Controlling peripheral devices

Which unit in the CPU is responsible for performing mathematical operations?

• Control Unit

• Memory Data Register

• Arithmetic Logic Unit

• Program Counter

What role does the control unit play within the CPU?

• It performs all arithmetic computations.

• It connects the CPU to peripheral devices.

• It stores data temporarily for quick access.

• It directs the operation of the processor.

What type of information is stored in the Memory Address Register (MAR)?

• Results of computations

• Addresses pointing to data locations

• Instructions for the CPU

• Data to be processed

What does the Memory Data Register (MDR) hold?

• The next instruction for the CPU

• Addresses of the next data

• Permanent storage files

• Data retrieved from memory locations

What is the function of the program counter in a CPU?

• To store the result of arithmetic operations

• To hold the address of the next instruction

• To control the input/output operations

• To manage the power supply to the CPU

What happens when the CPU needs to process an instruction from a specific memory location?

• The control unit powers down temporarily

• The data is deleted from the memory

• The address is stored in the accumulator

• The data is fetched and stored in the MDR

Which register is involved in storing the address of the next instruction to be processed?

• Accumulator

• Arithmetic Logic Unit

• Control Unit

• Program Counter

How does the accumulator assist in CPU operations?

• By directing data flow within the CPU

• By managing external device interactions

• By holding intermediate results of calculations

• By storing user data permanently
