in analog signal processing, bandwidth is the difference between two frequencies at the lower and upper boundaries of a continuous set. It is typically quantified in hertz. Ideally, a signal with a frequency that lies in the specified range passes through a medium without a significant amount of amplitude reduction.
* ඩෙසිබල් - මිණුම් ඒකකයකි a unit used to measure the intensity (තීව්රතාව )of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.
(in general use) a degree of loudness.

Noise is any type of disruption that interferes with the transmission or interpretation of information from the sender to the receiver.
In communication studies and information theory, noise refers to anything that interferes with the communication process between a speaker and an audience. It is also called interference.

Attenuation: attenuation is the reduction of the signal energy as it travels through the given medium. o Distortion: Distortion is alteration (distort) of properties of a transferred signal caused by the capacitance and inductance of the communication medium. o Simple topology: point-to-point connection: A Point-to-point topology connects two networking devices such as computers, switches, routers, or servers connected back to back using a single piece of cable.
attenuation. Attenuation is a general term that refers to any reduction in the strength of a signal. Attenuation occurs with any type of signal, whether digital or analog. Sometimes called loss, attenuation is a natural consequence of signal transmission over long distances.
In computer networking, attenuation is a loss of communication signal strength measured in decibels (dB). One of the methods used to increase signal strength to prevent attenuation issues is amplification.
Attenuation Demystified
Attenuation occurs on computer networks for several reasons:
range - both wireless and wired transmissions gradually dissipate in strength over longer reaches
interference - on wireless networks, radio interference or physical obstructions like walls also dampen communication signals
wire size - on wired networks, thinner wires suffer from higher (more) attenuation than thicker wires
