What is a Virtual Machine? A virtual machine is an instance of an operating system that is hosted on a physical machine by means of a software Virtualization platform. A virtual machine appears as a physical machine to the outside world and can be accessed as such. Because the Virtualization Platform presents physical machine resources to the Virtual Machines as generic resources‚ Virtual Machines do not require hardware specific drivers and can be ported across physical machines. According to VMware

Java Virtual Machine‚ An inside story!! Java Virtual Machine‚ or JVM as its name suggest is a “virtual” computer that resides in the “real” computer as a software process. JVM gives Java the flexibility of platform independence. Let us see first how exactly Java program is created‚ compiled and executed. Java code is written in .java file. This code contains one or more Java language attributes like Classes‚ Methods‚ Variable‚ Objects etc. Javac is used to compile this code and to generate .class

WHAT IS VIRTUAL MACHINE ? A virtual machine (VM) is a simulation of a machine (abstract or real) that is usually different from the target machine (where it is being simulated on). Virtual machines may be based on specifications of a hypothetical computer or emulate the architecture and functioning of a real world computer. A virtual machine (VM) is a software implementation of a machine (i.e. a computer) that executes programs like a physical machine. Virtual machines are separated into two

Virtual Memory Virtual Memory With today’s modern technology‚ we need to ensure that our computers are able to run quick and with ease. In order to run programs with speed‚ individuals need to ensure that they have sufficient memory to allow for programs running. Computers come with memory‚ but sometimes it is not enough to run what is needed or wanted. One way to ensure speed is to use virtual memory. Virtual memory can be described as memory that emulates RAM‚ and allows programs to

Virtual Reality In today’s world‚ making a mistake‚ for example during a surgery can be very fatal‚ but what if you make that same mistake but in a virtual reality? Well‚ if you make that mistake in the real world‚ you would learn from it but the patient would most likely have died but in a virtual world‚ you can program another virtual patient to retry the surgery knowing its not a real human. Virtual reality will have a substantial effect on our future way of life. Virtual reality already has

1. INTRODUCTION 1.1 Description about Virtual Reality Virtual Reality (VR) involves development of a computer generated virtual environment intended to simulate the real world. It is an emerging computer visualization technology that allows users to experience a strong sense of reality in a computer-generated environment. Engineers have begun to realize the usefulness of VR as an innovative tool to visualize‚ manipulate‚ and interact with complex three-dimensional (3-D) graphical data that
