In digital technologies there are lots of numbers. In fact there are the number systems binary, hexal, octal and our human readable dezimal system.
The dezimal system is only used by humans and a computer in its core is not able to make use of it, so we have to translate our „normal“ dezimal system to a computer readable number system.
The first number system which the computer uses to count etc. is the binary system. It is made up of 1 and 0.
