Binary And Denary
What is Binary (Base 2) and Denary (Base 10)?
Binary is a code made out of 1s and 0s and is recognised by all computers and can be used to express any number from 0 (00000000) to 255 (11111111). That is 8 bit which is 1 byte and 4 bit is a nibble. It is called base 2 because there are only 2 numbers: 0 and 1. Denary is what we use every day, it is the numbers 0 to 9. It is called base ten because there are ten numbers used in it.
