What does CPU stand for?

• Central Processing Unit

• Central Performance Unit

• Computer Processing Unit

• Core Processing Unit

What does clock speed mean?

• The number of calculations a computer can do per second

• The speed of data transfer

• The time taken to boot up

• The speed of internet connection

How does clock speed affect a computer's performance?

• The higher the clock speed, the faster a computer can run applications

• The lower the clock speed, the faster a computer can run applications

• Clock speed does not affect performance

• Clock speed affects only the internet speed

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

• Carries out instructions and calculations

• Manages inputs and outputs

• Stores data and instructions

• Carries requests for data

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

• Carries out instructions and calculations

• Manages inputs and outputs

• Stores data and instructions

• Carries requests for data

How does a larger cache impact the performance of a computer?

• Allows the CPU to store more data for processing

• Slows down the CPU

• Reduces the amount of data processed

• Increases the CPU's power consumption

What is the function of the Address Bus?

• Carries requests for data from the CPU to the RAM

• Carries data from the RAM to the CPU

• Manages the FDE cycle

• Stores data and instructions

What is the function of the Data Bus?

• Carries requests for data from the CPU to the RAM

• Carries data from the RAM to the CPU

• Manages the FDE cycle

• Stores data and instructions

What does the Data Bus do?

• Carries requested data from the RAM to the CPU/MDR

• Carries requests for data from the CPU to the RAM

• Manages inputs and outputs
