The binary number system is a numbering system that represents numeric values using two unique digits (0 and 1).
It is also called as base (2) number system. Each position in a binary number represents a 0 power of the base (2), that is, 20 . The last position in a binary number represents x power of the base (2), that is, 2x where x represents the last position 1.
The leftmost bit is called Most Significant Bit (MSB) and the rightmost bit is called Least Significant Bit (LSB).
