... that something like this is happening. If you're open to new ideas, and you have a good imagination, virtual reality may be a toy for you. What is VR? Virtual Reality grew out of flight simulation research during World War II and early computer graphics research in the 1960's. In 1965, computer scientist Ivan Sutherland published a paper describing "The Ultimate Display" and set the stage for research on the technology of Virtual Reality. Here's an excerpt from his paper: "The ultimate display would, of course, be a room within which the computer can control the existence of matter. A chair displayed in such a room would ...
... you want to go are registered you push the make destination button, and the computer programmes a route, the second after the route appears on the screen, while a voice explains it to you through the loudspeaker. c: The TravTek guides the driver through the traffic. The computer always knows where you are, and the navigation system makes it impossible to get lost in the traffic, unless you really want to, and deliberately make the wrong turns. It also guides you past traffic jams and problems who might crop up around an accident. In a town where you have never been, you will quickly be able to find your way to hotels, restaurants, sports arenas, shops and much ...
... Satellites. The Global Positioning System provides users with accurate information about their latitude, longitude, velocity and altitude, as well as the time, anywhere in the world and works in all weather conditions. The GPS was initiated in 1973 by Navstar in the United States and then followed by the Soviet Union with their own GPS. Both GPS systems are free to use by anyone around the world and offers great benefits to the military, commercial companies and civilian residents. On the military side, the U.S. Air Force uses the GPS to test unmanned prototype aircraft’s like the X-22, which can prevent unnecessary human casualties. The GPS is ...
... our arithmetic. In addition, this machine helps us think, write, draw, play music, learn, keep records and retrieve information. It is that we are using every day. The idea of an automatic computing machine can be traced back to the mid-nineteenth century. But it was only in the 1904s, when electronics was applied to the task of automatic computing, that fast, reliable computers became possible. Early computers were used mainly for scientific and technical calculations. In the 1950s, businesses, universities and government began using computers to store and process such nonmathematical data as orders, invoices, and personnel records. The use of computers for busin ...
... One is by vector graphics. Here the information in the picture is stored as mathematical equations. Engineering drawing applications such as CAD (computer assisted device) use this method. The other method is by bit mapped graphics. Here the computer actually keeps track of every point in the picture and its description. Paint programs use this technique. Drawing programs are usually vector mapped programs and paint programs are usually bit mapped. Computer sound is handled in two different ways. The sound can be described digitally and stored as an image (wave format) of the actual sound or it can be translated in to what is called midi format. This ...
... of Modems In the last 10 years, modem users have gone from data transfer rates of 300bps to 1,200 bps to 2,400 bps to 9,600 bps to 14.4Kbps to 28.8Kbps to, and to 33.6Kbps. Now new modem standards are emerging, reaching speeds of up to 56Kbps. Unlike the 33.6Kbps modems being sold today, 56Kbps is a significant improvement over 28.8Kbps modems. Viewing complex graphics or downloading sound files improves significantly with 56Kbps. The modem experts keep telling us that we are about maxed out. For instance when the 28.8 modems where first introduced they said that we've reached our maximum speed, and the same thing was said about the 33.6 and now ...
... than death. The use of the telephone has played an intricate role in the lives of millions. Everyone from the poorest man to the President of the United States uses the telephone. It is a luxury that is basically taken for granted. Before it was invented, it was very difficult to communicate with people who were a long distance away. But since its invention, the telephone has allowed us to contact just about anybody with just the push of a few buttons. It has indeed revolutionized communication. Without , there would in essence be no phone lines. Therefore, fax machines would be non-existent and the Internet wouldn’t even be a thought. The world that we w ...
... in the world today. Computer programmer write, test, and maintain computer programs or software. Programmers are often categorized as technicians because of the work they do. Many programmers are involved in updating, repairing, modifying and expanding existing programs. They are often grouped into two types. These two types are Applications programmers and Systems programmers. Applications programmers usually are oriented towards business, engineering, or science. They write software to handle specific jobs within an organization such as a program used in a place of business were a lot of inventory is being taken. They may also work alone to revise existing ...
... of the most extensive studies on Internet Addiction to date was conducted by Dr. Kimberly S. Young of the University of Pittsburgh at Bradford. In her study, she revealed concrete evidence supporting the Internet Addiction claim. However, help for web addicts is available. There are several web sites available for the treatment of Internet addiction, as well as counseling centers and clinics. Is it Live, or is it Internet? Internet Addiction The Internet is the largest most versatile source of information in the world today. With its web sites and chat rooms, it is a means of communicating with people in places all over the face of the earth. But with al ...
... you can determine your location with great precision. GPS is one of history's most exciting and revolutionary developments, and new uses for it are constantly being discovered. But before I go any farther it's important to understand a bit more about navigation. Since prehistoric times, people have been trying to figure out a reliable way to tell where they are, to help guide them to where they are going, and to get them back home again. Cavemen probably used stones and twigs to mark a trail when they set out hunting for food. The earliest mariners followed the coast closely to keep from getting lost. When navigators first sailed into the open ocean, t ...
