.... the development within technology, the military is now far more than just infantry whose task is to run around in the front line and fire their guns. Warfare is now totally dependent on sophisticated computer technology in numerous different areas. Examples are the navigation of a submarine and intelligent long-range missiles. What most people associates with computers and war may be various simulation and action games. This is big business for software developers and merchandisers all over the world. As in all businesses money is the most important criteria for the big companies so they have no morale problems with making warfare into entertainment a .....

.... access to residential users. It validates the hypothesis that upgraded cable networks can deliver residential Internet access more cost-effectively, while offering a broader range of services. The research for this report consisted of case studies of two commercial deployments of residential Internet access, each introduced in the spring of 1994: · Continental Cablevision and Performance Systems International (PSI) jointly developed PSICable, an Internet access service deployed over upgraded cable plant in Cambridge, Massachusetts; · Internex, Inc. began selling Internet access over ISDN telephone circuits available from Pacific Bell. Inter .....

.... standard. Millions of people worldwide are using the Internet to share information, make new associations and communicate. Individuals and businesses, from students and journalists, to consultants, programmers and corporate giants are all harnessing the power of the Internet. For many businesses the Internet is becoming integral to their operations.

.... replacing the letters of the alphabet with substitute letters from a certain number of places away. For example, let's say we decide to use the key "+4." That would mean we'd switch each letter in our message with the letter that comes four places later in the alphabet. D would become H; R would become V, and so on. You, or anyone else who knows the key can easily switch the H back to a D, the V back to an R, and figure out where to meet. Theses two examples are on opposite sides of the spectrum, but both have their similarities and their differences. The major difference complexity, the government pays mathematicians to research complex algorit .....

.... clutter and bounces it back to the squad car by way of wave guide antenna, which effectively confuses the computer inside the radar gun. Police radar takes five to ten speed measurements per second of the vehicle. The Phazer sends two different signals to the radar, so the final result is that police radar can not verify the speed of the vehicle and displays no speed at all. The Phazer also protects your vehicle from Lidar guns which use distance over time to detect the speed of the vehicle. The Phazer sends an invisible infared signals to the Lidar gun, this way the measurement of the speed is blocked. Many devices like that were outlawed .....

.... reserve and view it from different positions. You can see the area from any direction (north, south, east or west), and even from a helicopter position. Ecodisc lets you see the areas of the reserve from any part of the year. For example, you could view the reserve in the middle of winter and see what it looks like in summer. Ecodisc is one of the first interactive programmes, and there are hopes of some day there being interactive broadcast television. This is a breakthrough in visual entertainment, because while television lets you see a place, interactive video will let you explore it. Interactive video is where the viewer decides the plot a .....

.... become widely available. In almost any shopping mall we can now buy a machine that will not only do 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 sto .....
