➡️A tuple contain a group of elements which can be of different types. ➡️The elements in tuple are separated by commas, nd inclosed in parenthesis () ➡️tuple elements can't modified that means the value stored in a tuple can't be changed. ➡️that also means that a tuple can't be treated as a Read only list data type. therefore we can say that tuple is the oder list of object.

CU (Control Unit) is one of the two main components of the CPU. It deals with the coordination between the hardware devices attached with each either, works as an interactive bridge between software and hardware of the computer system.
ALU deals with all the mathematical and logical operations. More than one ALUs can be used for more powerful calculations. The ALU processes the data provided to the CPU as input, and it provides the information as the conclusion of the input in the form of output.	CU deals with the direction of all the tasks and operations performed by CPU. It coordinates and monitor the functionality of components and track the flow of data between the hardware components and the software.
ALU deals with the manipulation of the data and works according to the instructions provided by CU.	CU provides the instructions to ALU and coordinates according to the nature of data provided and nature of work to be performed.
