What is attenuation?
The degeneration of a signal over distance on a network cable is called attenuation.
rrsain
- Jan 12th, 2009
When we transmit any signal, the signal strength is degraded because of losses, interference, this is called attenuation of the signal. To reduce attenaution, repeaters are used to boost the signal strength.cheersrupesh

ISP Protocol
Which protocol is used to communicate between client and ISP?
tituxjec
- Mar 12th, 2009
OSPF is used. Because it is considered to be the most efficient IGP(interior gateway protocol). BGP is more widely used as exterior gateway protocol(EGP).

What is passive topology?
When the computers on the network simply listen and receive the signal, they are referred to as passive because they don�t amplify the signal in any way. Example for passive topology - linear bus.

Cable Length
Why do we have a minimum and maximum cable length requirement
badariprasad
- Jun 5th, 2009
The min and max cable length is required because the signals can travel effectively without loosing their strength to that extent you can increase the cable length apart from preferred by using the repeaters after the length so that the signals will be boosted again.
