To execute arithmetic operations

Question 5

What is the primary function of the address bus in a CPU?

Accepted Answer

To carry addresses from the CPU to other components

Answer

To carry data between the CPU and RAM

Answer

To connect the CPU to power supply

Answer

To control the flow of power in the CPU

Question 6

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

Accepted Answer

Data bus

Answer

Address bus

Answer

Power bus

Answer

Control bus

Question 7

What role does the control bus play in a CPU's operation?

Accepted Answer

To carry control signals from the CPU to other components

Answer

To transfer data between the CPU and hard drive

Answer

To connect the CPU directly to the monitor

Answer

To store temporary data in the CPU

Question 8

What distinguishes the data bus from the address bus?

Accepted Answer

The data bus carries actual data, while the address bus carries memory addresses

Answer

The data bus connects only to RAM, while the address bus connects to all components

Answer

The address bus is wider than the data bus

Answer

The data bus handles power supply, while the address bus manages data
