(In the network with twisted pair as the transmission medium, the manufacture and test of the jumper is very important. For small networks, jumpers connect hub devices and computers; for large and medium-sized networks, jumpers connect not only information sockets and computers, but also hub devices, jumper devices, and jumper boards. In short, in any case, the production and testing of patch cords is an entry-level manual that network administrators must learn.)
