## What is decimal, binary, octal and hexadecimal?

Decimal :

Decimal is nothing but the number we use in our day to day life. Whatever number we write in our day to day life, we use the ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Since we use one or some of these ten digits in decimal, we say  that  decimal is having base 10.

Binary:

In digital electronics, we write the numbers using only the two digits "0" and "1". Whatever number we we have in regular, it will be written in digital electronics only by using the two digits "0" and "1".

Since we use only the two digits "0" and "1" in binary, we say that binary is having base 2.

Octal:

Octal is nothing but the number we write using the eight digits 0, 1, 2, 3, 4, 5, 6, 7.

Since  we use one or some of these eight digits in octal, we say  that octal is having base 8.

Hexadecimal is nothing but the number we write using the sixteen digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F.

Here A =10, B = 11, C = 12, D = 13, E= 14, F = 16

Whatever number we have in regular, it will be written in hexadecimal using these 16 digits.

Since we use one or some of these 16 digits in hexadecimal, we say that hexadecimal is having base 16.

The above explanation of decimal, binary, octal and hexadecimal is more clearly shown in the below picture.
