Virtual Reality The definition of virtual reality comes‚ naturally‚ from the definitions for both ‘virtual’ and ‘reality’. The definition of ‘virtual’ is near and reality is what we experience as human beings. So the term ‘virtual reality’ basically means ‘near-reality’. This could‚ of course‚ mean anything but it usually refers to a specific type of reality emulation. So what is virtual reality? Answering "what is virtual reality" in technical terms is straight-forward. Virtual reality

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

I enjoyed doing the virtual lab. I treat water as an occupation so I understood how and what to add to treat the water. If you have a low (acidic) pH then you should add sodium hydroxide. If you have total coliforms‚ you should chlorinate before and after treatment. Often‚ we test houses for total coliforms and e. coli. If the bacteria is positive‚ then we chlorinate the well. After we make sure all the chlorine is throughout the house‚ we let it sit for 24 hours to disinfect the pipes and

Introduction and Thesis Nowadays‚ virtual techniques have become more and more popular. In the article I have chosen‚ the author believes that members of successful virtual collaboration teams (VCTs) need strong interpersonal and collaboration skills‚ which include establishing trust‚ embracing diversity‚ knowledge sharing and so on (Roy‚ 2012). In addition‚ compared to traditional face-to-face collaboration‚ this article also illustrates the advantages and disadvantages of VCTs. After reading

The default and recommended size of this file is 1.5 times the amount of physical memory. Virtual memory is the sum of physical memory and the page file

Virtual Reality Virtual reality has promise for nearly every industry ranging from architecture and design to movies and entertainment‚ but the real industry to gain from this technology is science in general. The money that can be saved examining the probability of experiments in an artificial world before they are actually carried out could be great‚ and the money saved on energy could be even greater. Virtual reality is something that personally excites me because uses and benefits of it are

Virtual memory is a feature of an operating system that enables a process to use a memory (RAM) address space that is independent of other processes running in the same system‚ and use a space that is larger than the actual amount of RAM present‚ temporarily relegating some contents from RAM to a disk‚ with little or no overhead. In a system using virtual memory‚ the physical memory is divided into equally-sized pages. The memory addressed by a process is also divided into logical pages of the
