                 An algorithm is a set of step-by-step instructions in a sequential manner to solve a problem.
                  The  raw  data  is  collected,  filtered,  sorted,  processed,  analyzed,  stored,  and  then  presented  in  a
                 readable format, called information.
                  Conditional statements are used in a program to instruct the computer to make a decision.
