we usually count in base 10 (1,2,3,4,5,6,7,8,9,10…), it’s called base ten because there are ten numbers used.
Base 2 uses only 2 numbers: 0 and 1
so you have 0, 1 , 10, 11, 100, 101 etc

you use the base to indicate that the given number is not in base 10, and to let know from which base needs to be converted
