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
