Many network hubs incorporate repeaters or amplifiers to regenerate signals so that attenuation of the signal does not occur?
As a rule a hub does not contain a repeater. Amplifiers would be used in analog communication, not digital communication.
Attenuation is a process that occurs all the time in networks; you would place a repeater in an area where the attenuation would cause the signal to degrade to the point where it wouldn't be usable. You would want the repeater to be placed before that point.

Which networking device receives a digital signal transmission via a medium and regenerates the signal along the next leg of the medium?
The networking device that receives a digital signal transmission and regenerates the signal for the next leg of the medium is called a repeater. Repeaters amplify or regenerate the signal to extend the transmission distance, ensuring that the signal maintains its integrity over longer distances. They are commonly used in various types of networks to overcome attenuation and maintain communication quality.
What advantage do regenerative repeaters have when used for digital communication?
When any digital signal is transmitted over a pair of wires, it degrades in amplitude. Regenerative repeaters receives the incoming signal, extracts the clock, then regenerates the original signal as a clean digital square wave as if it was the original signal transmitted from the source. Thus the name repeater.
What is regenrative repeater?
A: Signal travel in a line of sight on mountains there are repeater to by pass the mountain to the next town, A regenerative repeaters will restore this signal before it send it out again
What is the function of a repeater in terrestrial microwave transmission?
Repeaters may be installed with each antenna to increase the distance served by terrestrial microwave.Repeaters received the signals and converted into transmittable form and pass it to the next antenna.Repeaters can broadcast the regenerated signal at its original frequency or at modified frequency depends on the system
What is Analog carrier system used in telephony?
Analog Carrier System is a transmission system that uses repeaters that compensate for analog medium impairments, and produce output signals that are linear-scaled versions of input signals. Analog carrier systems can carry speech, data, video and supervisory signals although they are best suited for speech signals.
How are repeaters and regenerators used in telecommunication?
Repeaters take in a weak signal, regenerate the waveform and re-transmit it in a higher power level. So their function is basically to "boost" the signal, so that signal can cover longer distance without attenuation.
How do you reduce attenuation effects?
To reduce attenuation effects, you can use signal amplifiers to boost the signal strength, use high-quality cables with lower loss, minimize the length of the cable runs, and avoid sharp bends or kinks in the cables. Additionally, you can install signal repeaters or extenders along the transmission path to maintain signal integrity.
On a 10BASE-T network attenuation is addressed through the use of what?
repeaters
Why are repeaters used between computers?
Because - even in fibre-optic cable, distance brings attenuation of the signal. Repeaters boost the data stream to provide a constant signal level.
Which methods are used to overcome signal attenuation for terrestrial microwave transmissions?
Increasing the size of antennae Increasing the number of repeaters
What devices can have a wireless amplifier?
There are many different devices that have the capability of using wireless amplifiers. Any device, or network of devices, that produces radio signals, such as a WIFI network or a VHF radio system, can use wireless amplifiers or repeaters. These repeaters transmit signals further then the source transmitter can transmit. There are also numerous wireless amplifiers on the market to use with guitars.
What allowed long distance calls?
Distances gradually increased with the introduction of new equipment, such as relays, loading coils, amplifiers, and repeaters
Which network device regenerates the data signal without segmenting the network?
The network device that regenerates data signals without segmenting the network is a repeater. Repeaters are used to prevent attenuation of signals.
How do repeaters help networks?
A repeater connects two segments of your network cable. It retimes and regenerates the signals to proper amplitudes and sends them to the other segments. When talking about, Ethernet topology, you are probably talking about using a hub as a repeater. Repeaters require a small amount of time to regenerate the signal. This can cause a propagation delay which can affect network communication when there are several repeaters in a row. Many network architectures limit the number of repeaters that can be used in a row. Repeaters work only at the physical layer of the OSI network model.

How many types of repeaters are there?
Signal repeaters are generally used in the telecommunication and electronics industries. There can be passive radio signal repeaters, multi-port repeaters, optical signal repeaters for optical fiber and digipeaters which repeat packet data.
Which network topology do nodes act as repeaters?
Star Topology, where Hubs can act as repeaters.
