Java JVM

The JVM is a crucial component of the Java Platform introduced by Sun Micro Systems. It  is a set of computer data structures & programs which use a virtual machine model for the execution of other computer programs and scripts. The model used by a JVM accepts a form of computer intermediate language commonly referred to as Java bytecode.

Though Java Virtual Machines most often used to run Java (programming language) code. The JVM also enables such unique features as Automated Exception Handling 

The use of the same bytecode for diverse platforms allow Java to be called as "compile once, run anywhere", as opposed to "write once, compile anywhere", which describes cross-platform compiled languages.
