Question

How many values can be represent using a single bit?

Answer 1

I think it is 256. Because a byte has 8 bits . Each of the bit can be either 0 or 1. So for 8 bits - 2*2*2*2*2*2*2*2 = 256.

Answer 2

Computer only understands the sequence of 0s and 1s. One byte is equal to 8 bits and a collection of 8 bits can represent 256 messages . Thus, a single byte can represent 256 values
