.... at the same time. In 1935, the first radar systems are installed in Great Britain, called the Early Warning Detection system. In 1940, Great Britain and the United States install radar aboard fighter planes, giving them an advantage in plane-to-plane combat as well as air-to-ground attacks. Radar works on a relatively simple theory. It's one that everybody has experienced in their lifetime. Radar works much like an echo. In an echo, a sound is sent out in all directions. When the sound waves find an object, such as a cliff face, they will bounce back to the source of the echo. If you count the number of seconds from when the sound was made to when th .....

.... the most reliable but most people hate the idea of a laser shooting into their eye. Yet something such as monitoring keystroke patters people don't mind, but it's not nearly as effective. Biometric verification is forecast to be a multibillion dollar market in this decade. There is no doubt that financial credit and debit cards are going to be the biggest part of the biometric market. There are also many significant niche markets which are growing rapidly. For example, biometric identification cards are being used at a university in Georgia to allow students to get their meals, and in a Maryland day care center to ensure that the right person picks up .....

.... developments toward making life easier for the nearly blind and for the deaf, including on screen text to synthesize speech or Braille, and adaptive hardware that transforms a computers audible cues into a visual format. Computers have given the limited back their freedom to be an active part of the human race. According to the Americans with Disabilities Acts, any office that has a staff of more than fifteen people now has to provide adaptive hardware and software on their computers, so that workers with disabilities can accomplish many tasks independently. Before this Act was passed the disabled were normally passed over for jobs because of th .....

.... new area will be taken over by computers, namely maps. Different routes are stored on one single compact-disk. Imagine, simply insert the CD into the CD-driver in your car, and tell the computer where to go. The rest will be done automatically. This will be a safer, faster, and more comfortable way to travel. Another new area, called "virtual reality" is currently being tested. This is a way to simulate reality on a monitor. In order to feel this so-called reality you have to wear special electronic glasses and an electronic suit. Fastened to the suit are sensors, which send information to the main computer. This computer works with the data and displays them .....

.... In fact, Mike Elgan who is the editor of Windows Magazine, says " . . . the problem could cost businesses a total of $600 billion to remedy." (p. 1) The fallacy that mainframes were the only machines to be affected was short lived as industry realized that 60 to 80 million home and small business users doing math or accounting etc. on Windows 3.1 or older software, are just as susceptible to this "bug." Can this be repaired in time? For some, it is already too late. A system that is devised to cut an annual federal deficit to 0 by the year 2002 is already in "hot water." Data will become erroneous as the numbers "just don't add up" anymore. Some PC owners .....

.... Electronics also provide a superior tool for progression in the business world today. Business people rely on electronics to communicate with each other faster and to store and quickly organize vast amounts of essential data. Electronics are improving at a blindingly fast rate. The newest technology from five years ago is literally obsolete today. Electronics are also being used for new purposes continuously. The Internet, or World Wide Web, is a relatively new concept of being “on-line”. This new project has opened a limitless number of doors for our society. Now anyone can use the Internet to communicate with anybody else in the world a lot faster and .....

.... of all,without knowledge of computers anyone dont stand a chance on the job market. Because without education in this field there is no way to succed in life or to find ajob which would provide decant pay for an average person. However,other people have different opinion about this issue. In theit opinion knowledge of computers is not required in today's job market. They also thinks that people should not depend so much on computers but more on their own education and capibilities to make the right decisions. Even knowing for a fact that the computers are almost everywhere in use it's not appropriate for people to get addicted to them and to make them so .....

.... military since 1960s, but no one actually owns it. Thus, the Internet is a global network, and it crosses over different cultures. It is impossible to censor everything that seems to be offensive. For example, Vietnam has announced new regulations that forbid "data that can affect national security, social order, and safety or information that is not appropriate to the culture, morality, and traditional customs of the Vietnamese people." on June 4, 1996. It is also impossible to ban all things that are prohibited in a country. For instant, some countries, such as Germany, have considered taking measures against the U.S. and other companies or individuals that .....
