a passive hub does not regenerate the signal received only let it pass
The network device that regenerates data signals without segmenting the network is a repeater. Repeaters are used to prevent attenuation of signals.
hub
A transducer.
An active device amplifies the signal by some value - such as an active filter using an OPAMP. A passive device does not provide any amplification - such as a passive filter network of inductors and capacitors.
Repeater
passive
Passive hubs- do not amplify the electrical signal of incoming packets before broadcasting them out to the network.
Active device: A device that requires an external source of energy to be ready for operation and has an output that is a function of present and past input. e.g, Diodes, Transistors, PN and PIN junctions, ICs and varactors etc. we have to apply an external voltage usually called as Vcc, to these devices before placing in circuit network. Passive device: A device that does not require a source of energy for its operation. e.g, such as Resistors, Capacitors, Inductors, etc. We place thses devices in the circuit, network without applying any external voltage.
A passive device is a component that does not require power to operate. A lightning arrester on high voltage lines would fall into this category.
An optical line termination (OLT), is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions: - To perform conversion between the electrical signals used by the service provider's equipment and the fiber optic signals used by the passive optical network. - To coordinate the multiplexing between the conversion devices on the other end of that network (called either optical network terminals or optical network units).
a switch
Yes, it is classified as a 'passive' device.
