[KLUG Members] Java Complexity

[Adam Tauno Williams]

> JVM - kind of like the "kernel"

Only created when a Java application is invoked.  This isn't 'software'
exactly but a conceptual thing.

> JRE - Java runtime distribution for client workstations

Provides the software components to create a JVM and get a Java
application into it, as well as a bunch of files (libraries and what
not) that the Java application expects to find.

> JDK - JRE + developer tools

Yep.

> PlugIn - allows the web browser to communicate with the JVM to hava Java code
> run.

Usually provides integration between the browser and the installed JRE
so the JRE can create JVMs on behalf of the browser thus bringing the
Java parts of a website to life.
