Virtual Machine
Virtual Machine is a software simulation of a machine which can perform operations
similar to physical machine.
Virtual Machine is not physically present.
A virtual machine, usually known as a guest is created within another computing
environment referred as a "host." Multiple virtual machines can exist within a single
host at one time.

For eg. Calculator software in operating system, which is not physically present, but
performs all the functions similar to physical calculator.

Types of Virtual Machine :
1. Hardware Based or System Based Virtual Machine
2. Application Based or Process Based Virtual Machine

JVM (Java Virtual Machine) is Application Based Virtual Machine.

===================================

Java Virtual Machine (JVM) :

It is a Runtime Engine responsible to run java based applications.
It has two main tasks :
1. load .class file
2. execute .class file

Main components of JVM :
1. Class Loader
2. Memory Areas
3. Execution Engine
=========================

Class Loader :

It is responsible for the following three tasks :
1. Loading
2. Linking
3. Initialization
Loading
Linking :
In linking three activities are performed :
1. Verification
2. Preparation
3. Resolution
Initialization

====================================

Memory Areas :

Total 5 types of memory areas :
1. Method Area
2. Heap Area
3. Stack Area
4. PC Register
5. Native Method Area

===========

Execution Engine :
It is responsible to execute java class file.

It contains mainly two components :
1. Interpreter
2. JIT Compiler
