Can anybody give a brief difference between

jvm, jre, jdk and sdk.

as these terms are widely used in the java documentation, i want to have a basic understanding of these...

JDK and SDK are the same thing -- no idea why there are separate terms. JRE is only the runtime environment, which means it is the JDK minus the compiler and other stuff needed for development. JVM is one component of the JRE -- the virtual machine.
