How does gain affect noise?

Gain amplifies signals, including both desired and undesired elements like noise. Increasing gain boosts the overall signal, but it also elevates the noise floor, amplifying unwanted background noise or distortions. Higher gain intensifies both signal and noise, potentially reducing signal clarity and quality in audio, images, or electronic systems.
