Deck 9: Integration and Networking

Question 1

How does polling data transfer work?

Answer 1

Polling controls communication via the master or requesting unit sending a signal asking slave or sending unit if it has and data to send.If the answer is yes,the data are transmitted from the sending/slave unit.If the answer is no,the master/requesting unit moves on to the next node.
