=== '''Binary Number System''' === | |||
* A Binary number system has only two digits that are 0 and 1. | |||
* Every number (value) represents with 0 and 1 in this number system. | |||
* The base of binary number system is 2, because it has only two digits. | |||
* These number represent two logical conditions:TRUE and FALSE. | |||
=== Table: === | |||
=== '''Decimal number system:''' === | |||
* Decimal number system has only ten (10) digits from 0 to 9. | |||
* Every number (value) represents with 0,1,2,3,4,5,6, 7,8 and 9 in this number system. | |||
* The base of decimal number system is 10, because it has only 10 digits. | |||
