JAVA AND INTERNET:

   Java simplifies web programming.

   Java innovated a new type of networked program called the applet that changed the way the online world thought about contents.

   Java Applets:

o   An applet is a special kind of Java program that is designed to be transmitted over the internet and automatically executed by a java-compatible web browser.

o   An applet is downloaded on demand, without further interaction with the user.

o   An applet is a dynamic, self-executing program.

   Security:

o   Every time a program is downloaded, a risk is involved because the code which is downloaded might contain some virus, Trojan horse, or other harmful code.

o   Java achieved protection by confining an applet to the Java Execution environment and not allowing it access to other parts of the computer.

   Portability:

o   Portability is a major aspect of the internet because there are many different types of computers and operating systems connected to it.

o   Java achieves portability by using the concept of Java Virtual Machine and Byte Codes.
