Human intervention in terms of machine inference and working is inevitable. In the sophisticated, automated hi tech world of gizmo appliances and technology explosion human application has reduced to a considerable extent. The point is valid, but an important thing to ponder is that behind these series of inventions lie the inexplicable genius of human mind which has the power to think beyond imagination. If man made computers he understood that a medium would be required which would serve as an interface which would interact between the creator and its creation.

Ever since evolution mankind felt the need for calculation. Though the mediums and method could be diversified yet it was an acknowledged fact that numbers play a very important role in our life. Early dialects and numerals comprised of different formats and symbols of which nation India was a great contributor. With Aryabhattâ€™s invention of zero, numbers got a new dimension and thus came into existence the decimal format of numbers. With the introduction of zero decimal format was introduced which considered numbers in the form of base ten. The digits and the number places were defined in the power of ten, where the first digit was a unit, second digit in the place of ten and the third for hundred and the fourth for thousand and so forth.

For centuries decimal number ruled the world of numbers and even today we follow the decimal format for most of our arithmetic and calculations. With the introduction of computers however marked a new era of understanding the power of binary which though got its existence quite before yet got dominance or acceptance only with the introduction of computers. A computer understands machine level language and gradually got developed far superior to comprehend the high level languages which were more user friendly. This lead to the developments in the fields of number system where a method or a conversion system was required which could translate these high level languages into machine level languages and vice-versa. Thus came compilers and converters which translated and converted a decimal number system to binary system.

The conversion of decimal system into binary is a bit complicated than the conversion of binary to decimal. For the conversion of decimal into binary first all the decimal numbers are needed to be converted into binary equivalent and then through a very logical sequence these decimal digits get converted to the bits comprising zero and ones.

Decimal and binary number systems usually go parallel and correlate to each other. This sis far more true for a binary digit which does not have any significance beyond the calculations done by a system. The reason is obvious we always follow the decimal system in our daily and usual routine so we are not practiced neither habitual of expressing a numerical value in the terms of binary digits. Binary digits are only meant for computer calculations. The usual decimal number system that we follow is more convenient and practical as it is less lengthy and involves a range of numbers rather than the confusing amalgamation of only zeros and ones.
