I got this question in homework.

I want to ask this question from Introduction to Microcontroller topic in section Microcontroller Basics of Microcontroller

Answer 1

Correct answer is (c) data bus, address bus, control bus

Explanation: There are 3 buses present in a microcontroller 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).
