ORIGIN OF COMPUTERS

Origin  of  computer  could  be  rigorous  efforts  of  men  to  count  large  numbers.  This  process of  counting  of  large  numbers  generated  various  systems  of  numeration  like  Babylonian system  of  numeration,  Greek  system  of  numeration,  Roman  system  of  numeration  and Indian  system  of  numeration.  Out  of  these  the  Indian  system  of  numeration  has  been accepted  universally.  It  is  the  basis  of  modern  decimal  system  of  numeration  0-9.
