What does the data bus mainly carry?

Answer and explanation

Correct answer: Actual data between components

The governing concept is the division of roles among system buses. The data bus carries the actual values or instructions being transferred between the processor, memory, and other components for processing. Thus option B is correct. The address bus identifies the location involved, and the control bus carries timing or control signals; electrical power is supplied through power connections, not the data bus’s main role.
