(A) Address Bus
(B) Control Bus
(C) Data Bus
(D) All of these
🧠 Explanation:
The component used to transfer data between the CPU and memory is called the **System Bus** or **Data Bus**. It acts as a communication pathway that carries data, instructions, and addresses between the processor and the computer’s memory. Efficient data transfer through the bus is essential for the smooth operation of the computer, enabling the CPU to fetch instructions and read or write data quickly. Understanding the role of the system bus helps in grasping how different parts of a computer work together to perform tasks effectively.
