Adapter
Adapters are devices that create compatibility between sockets, plugs and cables that have different connections and thus make it possible to connect them with each other. With a gigabit adapter, for example, it is possible for a computer-capable terminal to be connected to an Rj45 Ethernet port via the USB connection. There are passive and active adapters. With a passive adapter, the connection between the devices is established via the pure transmitted signal, which is not changed. The active adapter, on the other hand, changes the signal, for example by changing the voltage. For the conversion of these signals by the adapter, it is equipped with additional components. These in turn must be supplied with power.
