CPU Functions Quiz

What is the main purpose of the CPU in a computer system?

• To store data permanently

• To execute instructions

• To connect to the internet

• To manage power supply

What happens during the fetch-execute cycle?

• The CPU stores data on the hard drive

• The CPU retrieves and processes instructions

• The CPU sends data to the printer

• The CPU saves files automatically

Which CPU component performs calculations and logical comparisons?

• Control Unit (CU)

• Cache

• Arithmetic Logic Unit (ALU)

• Register

What is the primary function of the Control Unit (CU)?

• Execute instructions

• Perform mathematical operations

• Manage the flow of data within the CPU

• Store frequently accessed data

What is the role of the cache in the CPU?

• Store frequently used data for quick access

• Manage the operating system

• Connect the CPU to peripheral devices

• Execute programs stored on the hard drive

Which of the following stores the address of the next instruction to be executed?

• MAR

• MDR

• Program Counter

• Accumulator

What does the Memory Address Register (MAR) hold?

• The result of a calculation

• The address of data to be accessed

• The instruction currently being processed

• The program's code

Which register holds the result of calculations performed by the ALU?

• MAR

• MDR

• Program Counter

• Accumulator

In the Von Neumann architecture, which component temporarily stores data being transferred to or from memory?

How does increasing the CPU clock speed affect performance?

• Increases data storage capacity

• Allows more instructions to be executed per second

• Reduces the CPU's temperature

• Improves battery life
