Wanli HUB, What kind of HUB has TYPE C port?
The main function of HUB is to regenerate, reshape and amplify the received signal to extend the transmission distance of the network, while concentrating all nodes on the node centered on it. It applies to the first layer of the OSI (Open Systems Interconnection Reference Model) reference model, the "physical layer". The hub is the same as the network card, network cable and other transmission media. It is a basic device in a local area network and uses CSMA/CD (Detection Protocol) access method.
According to the structure and function classification, HUB hubs can be divided into three types: unmanaged hubs, stacked hubs and chassis-type hubs. From the perspective of a local area network, hubs can be divided into single-hop hubs, multi-hop hubs, hub hubs, and hub hubs. Network segment hub, port switching hub, network interconnection hub and switching hub.
HUB is a pure hardware network bottom device, basically does not have the "smart memory" and "learning" functions similar to switches. It does not have the MAC address table that the switch has, so it does not use it as a target when sending data, but sends it through broadcast. In other words, when it wants to send data to a node, it will not directly send the data to the target node, but will send the data packet to all nodes connected to the hub.
