The processor uses the address bus to specify the memory location it wants to read from or write to by sending the corresponding address signals. Once the address is set, the data bus is used to transfer the actual data between the processor and the memory; it carries data to be written or read data from the specified address. The control bus carries control signals that manage the operations, such as read or write commands, ensuring that the correct actions are performed during communication. Together, these buses facilitate efficient data transfer and coordination between the processor and system memory.
