.... polygons necessary to visually describe the many objects in the scene. Change to the scene is governed by the computer simulation program or database driving the creation of the scene. Thus the visual quality of a VR experience is dependent on the speed of both the graphics-rendering hardware/software and the computer system itself. (Gump) There are four major types of devices currently in use: the head-mounted display (HMD), the binocular omni-oriented monitor (BOOM), the workstation "desktop" model (DEERING), and the projection model (CAVE). The HMD is a tracked helmet worn by the user that provides small television screens properly placed in fr .....

.... the early half of the twentieth century. Frederick W. Taylor is considered the father of operations management and is credited in the development of the following principles. a. Scientific laws govern how much a worker can produce in a day. b. It is the function of management to discover and use these laws in operation of productive systems. c. It is the function of the worker to carry out management's wishes without question. Many of today's method's of operation management have elements of the above stated principles. For example, part of Material Requirement Planning system (MRP) is learning how workers to hire, fire, or lay idle. This is .....

.... uses their computer to call and ISP, and the netcitizens computer temporarily becomes a part of the internet. The user is free to browse or transfer information with others. Most ISP's even allow their users to set up permanent homepages on the ISP's computer for the whole internet community to view. This is where many ethical and moral questions arise regarding the internet. Not every user wants his homepage to deal with the spin rates of atoms or the airspeed of South African swallows. Some users wish to display "objectionable" material on their homepages. This may have started out as a prank to some, but now net- porn is an offshoot industry .....

.... on that don't allow them to visit those web pages. If you aren't familiar with web pages, they are basically ads that you look at containing information about the company, person, or product. Also you can sign your child on as a child or teen which keeps them out of restricted areas. Perhaps your main concern is people finding out things that you don't want them to. They only know as much as you tell them. If they ask for your password, credit card number, or any other personal info, you don't have to tell them that information. When you first sign on AOL staff will ask for things like name, age, address, phone number, and your cre .....

.... directories that have been tagged with the purge attribute. As you can imagine these hidden deleted files can quickly eat up the space on a hard drive and the administrator will need to keep an eye on these so that the system is not unduly slowed down by the system purging to make room for saved and working files. These deleted files can also be purged manually with the SALVAGE utility, which is a great way to make sure that a file you don't want others to see is completely removed from the system!!! For a user or administrator to retrieve a file using SALVAGE, the create right (right to edit and read a directory area or file) must be assigned to .....

.... computing? Imagine you were in a large office building and you had to retrieve a briefcase left on a desk picked at random in one of hundreds of offices. In the same way that you would have to walk through the building, opening doors one at a time to find the briefcase, an ordinary computer has to make it way through long strings of 1’s and 0’s until it arrives at the answer. But what if instead of having to search by yourself, you could instantly create as many copies of yourself as there were rooms in the building all the copies could simultaneously peek in all the offices, and the one that finds the briefcase becomes the real you, the rest j .....

.... Licensing agreements can often be purchased for additional users for less than the cost of additional full copies. Physical Resources Printers and backup systems are two examples of special hardware which often have low use rates. By setting up several computers to share these resources, money is saved from having to provide (for example) each user with their own printer. Fewer peripherals also can translate into lower maintenance costs and lower capital investments on the system as a whole. TYPES OF NETWORKS Networks fall into two categories: Server-Client, and Peer-To-Peer. Server-Client is often the fastest (and more expen .....

.... The thrill of the hack is not in breaking the law, it's in the pursuit and capture of knowledge. To this end, let me contribute my suggestions for guidelines to follow to ensure that not only you stay out of trouble, but you pursue your craft without damaging the computers you hack into or the companies who own them. I. Do not intentionally damage *any* system. II. Do not alter any system files other than ones needed to ensure your escape from detection and your future access (Trojan Horses, Altering Logs, and the like are all necessary to your survival for as long as possible.) III. Do not leave your (or anyone else's) r .....

Not only you should kill the other players but you should watch out for a creature that could grab you and kill you.

.... up. Because so many people wanted to use the Net, ARPANET started getting hard to manage, especially with many university sites on it. Therefore, it was broken into two parts: MILNET, which had all the military sites, and ARPANET, which had all the nonmilitary sites. "The two networks remained connected, however, thanks to a technical scheme called IP (Internet Protocol), which enabled traffic to be routed from one net to another as needed. All the networks connected by IP in the Internet speak IP, so they can all exchange messages." (Levine 12) Even though there were only two networks at that time, IP was made to allow thousands of networks. .....
