CHAPTER 1. THE MENTAL LANDSCAPE 16is intimately associated with the Internet and the World-Wide Web. As you have seen in theprevious section, special Java programs called applets are meant to be transmitted over theInternet and displayed on Web pages. A Web server transmits a Java applet just as it wouldtransmit any other type of information. A Web browser that understands Java—that is, thatincludes an interpreter for the Java virtual machine—can then run the applet right on the Webpage. Since applets are programs, they can do almost anything, including complex interactionwith the user. With Java, a Web page becomes more than just a passive display of information.It becomes anything that programmers can imagine and implement.But applets are only one aspect of Java’s relationship with the Internet, and not the majorone. In fact, as both Java and the Internet have matured, applets have become less important.At the same time, however, Java has increasingly been used to write complex, stand-aloneapplications that do not depend on a web browser. Many of these programs are networkrelated.For example many of the largest and most complex web sites use web server softwarethat is written in Java. Java includes excellent support for network protocols, and its platformindependence makes it possible to write network programs that work on many different typesof computer.Its association with the Internet is not Java’s only advantage. But many good programminglanguages have been invented only to be soon forgotten. Java has had the good luck to ride onthe coattails of the Internet’s immense and increasing popularity.
Quiz 17Quiz on Chapter 1(answers)1. One of the components of a computer is its CPU. What is a CPU and what role does itplay in a computer?2. Explain what is meant by an “asynchronous event.” Give some examples.3. What is the difference between a “compiler” and an “interpreter”?4. Explain the difference between high-level languages and machine language.5. If you have the source code for a Java program, and you want to run that program, youwill need both a compiler and an interpreter. What does the Java compiler do, and whatdoes the Java interpreter do?6. What is a subroutine?7. Java is an object-oriented programming language. What is an object?8. What is a variable? (There are four different ideas associated with variables in Java. Tryto mention all four aspects in your answer. Hint: One of the aspects is the variable’sname.)9. Java is a “platform-independent language.” What does this mean?10. What is the “Internet”? Give some examples of how it is used. (What kind of servicesdoes it provide?)
