In star topology, computers are connected by cable segments to a central component, called concentrator (hub). Signals are transmitted from the transmitter computer via concentrator to all hosts. This topology has its origins in the early days of computing, when all computers in an institution were connected to a central computer (mainframe). If a computer, or you Connect the cable concentrator fails, only the computer that is unable to transmit or receive data network, the rest of the network will continue to function normally. But if the concentrator fails, the entire network fails.
Most concentrators are active, meaning that regenerate and transmit signals, as receivers. For 8 to 12 ports for connecting computers in network concentrators are also called multiport repeaters. To work, assets must concentrators supplied with electricity. Certain types of concentrators are passive, such as panels or wiring connection blocks. They only act as connection points without amplify or regenerate the signal passing through the concentrator unchanged.
Passive concentrators do not need electricity to operate. Modern concentrators, which can connect different cable types, concentrators are called hybrid. A network can be expanded by connecting multiple concentrators.
