He discusses how biological cells perform reliable computation with unreliable components and noise (which refers to random variations in signals - whether electronic or genetic).
What's more, any background noise will be different from the noisesignals we are working with, making it possible to subtract its effect.
更进一步,任何背景噪音将和我们使用的噪音信号有所不同,这样我们就可以把他们的影响减去。

A t its most fundamental, computer science is about the search for better algorithms - more efficient ways for computers to do things like sort data or filter noise out of digital signals.
