            \n
          1. Binary Number<\/strong>:
            A binary number is a number expressed in the base-2 numeral system, which uses only two digits: 0 and 1. Each binary digit represents an increasing power of 2, starting from the rightmost digit (least significant).<\/li>\n\n\n\n
          2. Octal Numbers<\/strong>:
            Octal numbers are numbers in the base-8 numeral system, which uses digits from 0 to 7. It is commonly used in computer science as a shorthand for binary numbers, since one octal digit represents three binary digits.<\/li>\n\n\n\n
          3. Decimal Number<\/strong>:
            Decimal numbers are numbers expressed in the base-10 numeral system, which uses digits from 0 to 9. It is the standard system for denoting integer and non-integer numbers.<\/li>\n\n\n\n
