To quote the old Q code, Noise is QRN and interference is QRM. Noise is natural or accidental, caused by natural sources or accidentally by operating electrical machinery. Interference is man made, either deliberately to obstruct legitimate communications, or accidentally due to adjacent frequencies or locations being used.
The borderline is indistinct. Don't get me going about flak and fruit.
Noise is defined as unwanted sound. If there is nobody there, a tree falling in the forest makes no noise.
Sound is what we perceive with our ears in response to a variation in air pressure, occurring at a frequency to which they will respond.
Music (or vocals) are sounds that we find pleasing or to which we react. But some folk are stirred by the skirl of the pipes, and others are repelled.
Music is a group of sounds that have been deliberately produced to make a regular pattern, but noise is usually a group of sounds with no regular pattern.

The vibrations of the air within the range of human hearing is known as sound.
Noise is defined as unwanted sound.
Interference is caused when two or more signals interfere with each other.
the effect of the interference is known as noise.

Signal to noise ratio is the difference between the noise floor and the reference level.
The two are totally unrelated. Classes means categories. It is also used as a programming concept. Interference is a phenomenon that happens when two waves meet.
ANALOG:continuous,rate of transmission is slow,less reliable 2 transmit,more noise,interference is more DIGITAL:non continuous,rate of transmission is fast,more reliable 2 transmit,less noise,interference is less
Thermal noise
SINR - Signal to Interference and Noise Ratio CINR - Carrier to Interference and Noise Ratio difference between those to is difference between carrier and signal carrier is signal who doesn't "carry" any information . it must be modulated( by phase,freq or amplitude) and those changes convey information. carrier is unmodulated signal signal is defined as useful signal which carries information SINR is power of signal to power of interfenence and noise ratio
Interference and noise are distinguished the same way in all situations not just optical communication. Noise is caused by random thermal effects or statistical effects to to the randomized distribution of electron flow. Interference is due to a system being sensitive to external perturbation, due to weather, dust, vibration etc.
No. Fiber is immune to electrical interference; there is no cross-talk between signals in different cables and no pickup of environmental noise.
Constructive interference occurs when two waves meet in phase, resulting in an increase in amplitude. Destructive interference occurs when two waves meet out of phase, resulting in a decrease in amplitude or cancellation of the waves.
Current measures flow of charge. Interference is something that gets in the way.
Data is information while interference is a noise being introduced from other sources. Thus, data interference is an information with noise and that its integrity can not be ascertained.
a noise of a computer is lower than atelivision
They dont make noise only interference
Music can be coined as structured, organized noise.
Twisting wires is done the prevent electromagnetic interference between the circuits(known as noise).
Destructive interference lowers the amplitude, the lowest amplitude will be the difference between the two waves.
No, the phase difference between the nodes produced by two violins is not constant and so the interference is not possible.
