Each binary digit is called a bit. In the number 11000000b, each 1 is a bit, and each 0 is a bit. The number of bits present is what is referred to when we say things like “8-bit,” “16-bit,” or “64-bit.”
A bit is a binary digit that represents a value. This works well for computers and digital devices because the bits 0 and 1 can represent the states on and off, which corresponds to the on or off flow of electrical current through the computer’s hardware.

how do we know which is decimal, which is binary, and which is hexadecimal? All three numbers look alike because they use the same digits, 0 and 1, but all three represent different values in different number systems. Surely, there must be a way to avoid ambiguity, right?
Indeed there is.
To facilitate readability and conserve space when viewed in a monitor or in print, we use the hexadecimal (base 16) system as a shorthand to represent binary.
