Detailed explanation-1: -There are 3 buses present in a micro controller they are data bus (for carrying data from one place to another), address bus (for carrying the address to which the data will flow) and the control bus (which tells the controller to execute which type of work at that address may be it read or write operation).
Detailed explanation-2: -There are three types of bus lines: Data bus, Address bus, and Control bus. Communication over each bus line is performed in cooperation with another. The data bus is a signal line for exchanging the data between the CPU and the memory, and between the CPU and I/O, and handles the data stored in the specified location.
Detailed explanation-3: -An address bus is a computer bus architecture used to transfer data between devices that are identified by the hardware address of the physical memory (the physical address), which is stored in the form of binary numbers to enable the data bus to access memory storage.
