The JVM (Java Virtual Machine) describes the actual 'application' whose job it is to translate Java Bytecode (what your class files compile into) into native machine code for whatever system it is running on. The JRE (Java Runtime Environment) describes not only the JVM itself, but also any plugins, additional APIs, etc.At least, this very simple answer is what I go by.

Java Virtual Machine(JVM) is program that executes the bytecode generated as a result of compilation whereas Java Runtime Environment(JRE) provides an environment in which Java applications are compiled & executed that is JRE incorporates JVM within itself.To execute any Java Program or Application you must have JRE which is installed when you install jdk
