The Structure and Function of the CPU

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

• To store data

• To process data

• To display graphics

• To manage network connections

What are the three steps the CPU follows to process data?

• Fetch, Decode, Execute

• Load, Process, Save

• Input, Process, Output

• Start, Run, Stop

Where are the data and instructions loaded when you open a program?

• Hard Drive

• CPU

• RAM

• Cache

What is the temporary memory called where the CPU stores fetched data and instructions?

• Cache

• Registers

• RAM

• Hard Drive

What hardware path does the CPU use to fetch data from the main memory?

• Data Bus

• Address Bus

• Control Bus

• Memory Bus

What is the purpose of the 'Data Bus' in the CPU?

• To store data

• To fetch instructions

• To transfer data from RAM to CPU

• To decode instructions

What is the role of the Control Unit in the CPU?

• It performs arithmetic and logical operations.

• It controls the signals required to coordinate the running of the processor.

• It stores data temporarily.

• It moves data between the CPU and main memory.

Which component of the CPU is responsible for calculation and decision making?

• Control Unit

• Registers

• ALU

• Data Bus

What is the function of the Registers in the CPU?

• They control the signals required to coordinate the running of the processor.

• They perform arithmetic and logical operations.

• They are the CPU's own memory store which is extremely quick.

• They move data between the CPU and main memory.

Which bus is responsible for moving data between the CPU and the main memory?

• Address Bus

• Data Bus

• Control Bus

• Instruction Bus
