Virtual Network Computing (VNC) is a desktop sharing system which uses the RFB (Remote FrameBuffer) protocol to remotely control another computer. It transmits the keyboard presses and mouse clicks from one computer to another relaying the screen updates back in the other direction, over a network.VNC is platform-independent: a VNC viewer on any operating system can connect to a VNC server on any other operating system. There are clients and servers for almost all operating systems and for Java. Multiple clients may connect to a VNC server at t ....etc

1. INTRODUCTION

Have you ever found yourself away from home, wishing you had your desktop machine with you? Have you ever wished you could show someone, remotely, how to do something instead of talking them through it over the phone? These things and much more can be done with a nifty little freeware utility called Virtual Network Computing, or VNC.

What VNC does is this: it enables a remote user (who knows the password) to take control of your machine via the internet. They can view files, run programs, delete stuff, etc. -- in other wo ....etc

open source
(1) Generically, open source refers to a program in which the source code is available to the general public for use and/or modification from its original design free of charge, i.e., open. Open source code is typically created as a collaborative effort in which programmers improve upon the code and share the changes within the community. Open source sprouted in the technological community as a response to proprietary so ....etc

ABSTRACT:- In the autumn of 1969, we decided to try a new approach to the design of a virtual machine operating system. Until that time, most installations using Virtual Machine Monitors merely ran operating systems that already existed for €œstand-alon use. Few, if any, installations had attempted to design and create an operating system that took advantage of its running environment. The Virtual Machine Monitor we were using was a highly modified version of CP-67 which was designed to operate on an IBM S/360 Model ....etc

ABSTRACT
A supercomputing facility at campus can contribute to scientific and academic research with its enormous
computational power. But setting up a supercomputing center based on “off the shell” server class
microprocessors as a cluster require huge investment and maintenance cost. We therefore intro ....etc

Seminar on The Virtual Machine



A virtual machine (VM) is a software implementation of a computing environment in which an operating system (OS) or program can be installed and run.
The virtual machine typically emulates a physical computing environment, but requests for CPU, memory, hard disk, network and other hardware resources are managed by a virtualization layer which translates these requests to the underlying physical hardware.
