Hub is repeater or amplifier? 1

[Guest_imported]

If iam right we don't have amplifiers in digital electronics.So hub works as repeater or amplifier.
Thank you.

A hub is a reapeater.

For sure, there is not a repeater, if anything we would have a switch but the hub is like a junction for multi routes

A hub absolutely is a repeater, although that isn't necessarily its *primary* function in most cases. Think about it - one station transmits and the signal gets repeated on all other ports. You don't think that is done on a physical bus do you?

Hub is not a repeater, it can not add anything to a transmitted packet; It is just act as a connector.

A hub is a repeater (of sorts). It takes a digital signal and repeats (or re-transmitts) that signal to all other ports. It DOES NOT amplify the signal. If it did it would also amplify the noise on the cable and transmission at longer distances would not work.

A hub is a repeater... it can be used to make a signal stronger, via re-trasmitting it. IProute above has hit the nail on the head. Well described!!
