To keep records and communicate information
Step-by-step explanation:
A quipu is also called khipu by others, happened to be a method that was used by the Incas and some other ancient Andean cultures. They use the quipu in order to be able to keep records or even to communicate information. Since there wasn't and form of alphabetic writing system as at that period in time, the quipu served as quite a simple and highly portable device that possessed a rather surprising degree of precision and flexibility for a device existing at that point in time.
