Signal-to-noise ratio (often abbreviated SNR or S/N) is an electrical engineering concept defined as the ratio of a given transmitted signal to the background noise of the transmission medium. It is also known as D/U ratio, which stands for desired to undesired signal ratio.

hope this helps I am not as intelligent as the rest of the guys here, perhaps someone can give you a simplified answer

Basically means how loud the noice/interference is compared to the sound you do want to hear! :)

Yep, anything with a ratio of over 100db is good.
Also look out for 'slew rate'. This tells you how good the amp is at reproducing the input signal. The higher, the better.
