                    ¨  An algorithm is a 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.
                    ¨  Binary code is the fundamental form of the programming data that is directly interpreted by a
                       computer.
                    ¨  Conditional statements are used in a program to instruct the computer to make a decision.
