Computing Dictionary
 
 Definition: 

(JVM) A specification for software which interprets java programs that have been compiled into byte-codes, and usually stored in a ".class" file. The JVM instruction set is stack-oriented, with variable instruction length. Unlike some other instruction sets, the JVM's supports object-oriented programming directly by including instructions for object method invocation (similar to subroutine call in other instruction sets).

The JVM itself is written in c and so can be ported to run on most platforms. It needs thread support and i/o (for dynamic class loading). The Java byte-code is independent of the platform.

There are also some hardware implementations of the JVM.
