Client-Server Computing
Java and JavaScript
- Javascript is a "scripting" language that allows you to embed programming instructions in an HTML document. It was developed by Netscape to add functionality to web pages.
- Java is a complete programming language first developed by Sun Microsystems in the early 1990s. There are 3 basic kinds of Java programs: applications, applets (that run on the client), and servlets (that run on the server). We will work with applets and applications in this class. Java programs are compiled into "byte code" for a "Java virtual machine." Each computer will have is own Java interpreter (which may be part of a browser) to run the Java byte code.
