The Java platform, which consists 3 major parts: Java programming language, Java Virtual Machine (JVM), and several Java Application Programming Interfaces (APIs), was developed at Sun Microsystems in the early 1990s.
JVM stands for Java Virtual Machine, it is software.
A Java Virtual Machine enables a set of computer software programs and data structures to 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. A virtual machine is a software implementation of a machine (i.e. a computer) that executes instructions (not programs) like a physical machine.
Java is defined by a specification and consists of a programming language, a compiler, core libraries and a runtime (Java virtual machine) The Java runtime allows software developers to write program code in other languages than the Java programming language which still runs on the Java virtual machine. The Java platform is usually associated with the Java virtual machine and the Java core libraries.

One could find more information about the Java Virtual Machine online on various websites such as 'Wikipedia', 'Java-Virtual-Machine' and of course the website 'Java'.
Java created a file called class, and is identified by having the .class at the end. This file includes a Java bytecode, which then can be used on the Java Virtual Machine.
That's short for Software Development Kit, and it is basically everything the programmer (developer) needs to program in Java. It includes the Java compiler, the Java Virtual Machine, and the Java base classes.
Answer: JVM is nothing but java virtual machine,it is a software used to convert the bytecode(highly optimizes set of instructions) to machine code. so, now applet is a small java program run by a web browser.thus now we can understand for what JVM is used or mean in applets.Answer: In other words, JVM (Java virtual machine) is simply the component used to run software written in the Java language.
The company that makes the software known as "Jinitiator" is Oracle Corporation. The software Jinitiatir is a JVM which stands for Java virtual machine.
Modern machines do not consist of multiple levels of virtual machines; that is a function of the host operating system's virtual machine manager and its guest operating systems, all of which are implemented through software. The operating system's virtual machine manager exposes one or more virtual machines upon which you can host one or more guest operating systems and their applications. In order to execute compiled Java applications upon one of these guest operating systems you will also need to install the Java virtual machine for that specific operating system. Thus you end up with a Java program executing within a Java virtual machine executing within a virtual machine executing within a virtual machine manager executing upon the physical hardware. The physical hardware itself may be optimised to handle virtual machine managers more efficiently, but the virtual machine manager is a software program; it is not part of the physical machine architecture
