1、Overview
(Universal Asynchronous Receiver/Transmitter)， It is called "UART" and is a part of computer hardware. It converts the data to be transmitted between serial communication and parallel communication. As a chip that converts parallel input signals into serial output signals, UART is usually integrated into the connections of other communication interfaces.

HUB also means "center". The main function of a hub is to expand physical ports and regenerate, shape, and amplify received signals to increase the transmission distance of the network, while concentrating all nodes on the nodes centered around it.
