What are the three busses that allow the cpu to communicate with primary memory?

• Peripheral Bus, Cache Bus, System Bus
• Address Bus, Data Bus, Control Bus
• Control Line, Data Line, Address Line
• Signal Bus, Memory Bus, I/O Bus

What is the role of the address bus?

• The address bus allows the cpu to specify which memory address it wishes to work with.

• The address bus is responsible for executing instructions.
• The address bus connects the CPU to the power supply.
• The address bus transfers data between the CPU and RAM.

What is the role of the control bus?

• The control bus manages the power supply to the computer.
• The control bus connects the CPU to the hard drive.
• The control bus transmits control signals to coordinate the actions of the CPU and primary memory.

• The control bus stores data temporarily for processing.

What is the role of the data bus?

• The role of the data bus is to transfer data between the CPU and main memory.

• The data bus is responsible for executing instructions.
• The data bus connects only the CPU to the hard drive.
• The data bus is used for power supply to the CPU.

What is the role of the control unit?

• The control unit is responsible for managing the computer's memory.
• The control unit stores data temporarily for quick access.
• The control unit directs the operation of the CPU and also decodes instructions.

• The control unit handles input and output operations directly.

What is the role of the Arithmetic Logic Unit?

• To store data temporarily during calculations.
• To manage input and output devices.
• To control the flow of data between memory and storage.
• To perform calculations and the comparison of values.
