Correct answer: D
The data bus is a collection of wires or pathways designed to transfer actual data (like instructions, numeric values, or characters) between the main core components of a computer system.
It acts as a shared highway connecting:
The CPU: To fetch instructions and process data.
Memory (RAM): To read data from or write data back to storage.
Input/Output (I/O) Devices: To send or receive data from peripherals like keyboards, hard drives, or monitors.
