Active
The function of regenerating and amplifying the signal on the connected network medium can make the length of the connected medium reach the maximum effective length, and it needs a power source to work. At present, most HUBs are of this type.
passive
Passive only acts as a connector, which can work without a power supply, and is rarely seen on the market.
mixed type
Hybrid USB hubs can connect multiple types of cables, such as shafts and twisted pairs.
A USB hub is an important tool for centralized management of networks. Like the trunk of a tree, it is a collection point for each branch. HUB is a shared device, which is essentially a repeater, and the main function of the repeater is to reproduce and amplify the received signal to expand the transmission distance of the network. In the network, the hub is mainly used for the construction of the shared network, and it is the best and most economical solution to solve the problem from the server directly to the desktop. In a switched network, the HUB is directly connected to the switch and sends the switch port data to the desktop. HUB networking is flexible. It is a star node of the network and centrally manages the workstations connected to the nodes. It does not let the workstations in question affect the normal operation of the entire network. Because HUB plays an important role in the network, it is also very important for its selection.
USB hub can be connected with computer desk lamp, computer fan, MP3, U disk, voice recorder, digital camera and so on.
