The internet helped catapult Java to the forefront of programming and java, in turn, has had a profound effect on the internet. The reason for this is quite simple. Jave expand the universe of objects that can move about freely in cyberspace. In a network, two very broad catagories of object that can move about freely in cyberspace. In a network, two very broad catagories of objects are transmitted between the server and your personal computer. passive information and dynamic, active programs. For example, when you read your e-mail, you are viewing passive data. Even when you download a program, the program's code is still only passive data untill you excute it. However, a second type of objects can be transmitted to your computer: a dynamic, self -executing program. Such a program is an active agent on the client computer, yet is initieted by the server. For example, a program might be provided by the server to disply properly the data that the server is sending.
As desirable as dynamic, networked programs are, they also present serious problems in the areas of security and portablity. Prior to java,cyberspace was effectively closed to half the entities that now live there. As you will see, Java addreses those concerns and, by doing so, has opened the door to an exciting new form of program: the applet.
