Binary number system is has 2 as its base. The way we have digits 0-9 in a decimal system and 10 is the base, we have digits 0 and 1 in a binary system whose base is 2.

In decimal a number is represented as follows using the positional values which are powers of 10.

145 = 1*10^2 + 4*10^1 + 5*10^0

Similarly a binary number is calculated as follows using the positional values which are powers of 2.

1011 = 1*2^3 + 0 + 1*2^1 + 1*2^0 = 8 + 0 + 2 + 1 = 11 in decimal.

The binary system is used in computing since basically we have two states high voltage and low voltage which can travel on a wire and combinations of these are used to represent different values.

As computer operates on electricity, so it can underastand only in terms of high and low voltage.Generally,low voltage means 0 and 1 for high voltage.thus all languages are converted to binary system for system to execute.

computer cannot identify the numbers other than 1 and 0.because it can only understand whether there is a presece of volage or absence.so for low voltages like 0-1 volts it considers off and for 4-5 volts it considers on.so we use binary system in computers or in any other electronic devices.by taking the combinations of 1 and 0 it can understand all the remaining numbers.

Because Internally data is stored in transisitor  and it can be turned on or off depending on the voltage level .

1-ON

0-Off

Hence data is stored as 1's and 0's

binary system is used based on 0 - off and 1 - on
