Understanding CPU Architecture and Functions

What is the primary function of the CPU in a computer system?

• To store data permanently

• To process data and instructions

• To provide power to the computer

• To display graphics

Which architecture is commonly associated with the CPU's operation in a computer system?

• Harvard architecture

• Von Neumann architecture

• RISC architecture

• CISC architecture

What is the first stage of the Fetch-Decode-Execute cycle?

• Execute

• Decode

• Fetch

• Store

During the Fetch stage, where is the memory address of the instruction stored?

• Program Counter

• Memory Data Register

• Current Instruction Register

• Memory Address Register

What is the role of the Control Unit (CU) in the CPU?

• To perform arithmetic operations

• To control all operations in the CPU

• To store data temporarily

• To manage power supply

Which bus is used to transfer the memory address from the CPU to the memory?

• Data bus

• Control bus

• Address bus

• System bus

What happens to the Program Counter during the Fetch stage?

• It decrements

• It remains unchanged

• It increments

• It resets to zero

In the Decode stage, where are the instructions received?

• Arithmetic Logic Unit

• Control Unit

• Memory Data Register

• Program Counter

What is a microprocessor?

• A type of memory

• An integrated circuit that performs CPU functions

• A storage device

• A power supply unit

Which register temporarily holds the data/instruction fetched from memory?

• Program Counter

• Memory Address Register

• Memory Data Register

• Current Instruction Register
