since there are only two digits in binary system i.e,,computer uses digital system instead of analog signals which has infinite no of values.also noise level in the case of digital signals is very much low when compared to analog signals.

One of the main advantages of digital signals is that unlike analog signals which can expected to represent an infinite number of values in the signal, a basic digital signal only represents two values – 0 and 1. This makes it possible to suffer huge amounts of noise that would typically cripple an analog circuit.
