Binary Number Systems
As mentioned earlier this number is used by digital systems like microprocessor and other digital circuits. This number systems use only two digits zero and one each binary digit is called a bit. But for digital systems the meaning of and are different. For these systems it means two distinct states like switch off/ on voltage low / high current in the line no/ yes. In different parts these two states might be different which may be denoted by 0 and 1. In this sense we can say digital systems understand 0 and 1 hence to use such systems we have to learn binary number systems. As we use decimal number systems we should know how to convert a number from decimal to binary and vice versa.
