9. public class Game { Car f1; f1.spin(); } The set of instructions that tells a computer what to do is called a program

10. public class Game { Car f1; f1.spin(); } Software is the name given to a single program or a set of programs.

11. Application software is the name given to useful programs that a user might need.

12. System software is the name given to special programs that help the computer to do its job.

13. public class Game { Car f1; f1.spin(); } Programming is the task of writing instructions for the computer

14. public class Game { Car f1; f1.spin(); } These instructions have to be written in a special programming language.

15. public class Game { Car f1; f1.spin(); } Examples include: C++, Visual Basic, Pascal, Java.

16. public class Game { Car f1; f1.spin(); } Examples include: C++, Visual Basic, Pascal, Java.
