In a binary number system, there are only two possible states, HIGH state and LOW state.
These two states can be represented by current levels, voltage levels, bumps and valleys on the surface of CD/DVD etc.
The two states are generally represented by a ‘0’ for LOW state and by a ‘1’ for the HIGH state.
Using the combination of 0’s(LOW) and 1’s(HIGH), we can represent the other number systems such as hexadecimal, octal or decimal into
binary number system.
