... placed into orbit around the Earth to facilitate communications on Earth. Most long-distance radio communication across land is sent via MICROWAVE relay towers. In effect, a satellite serves as a tall microwave tower to permit direct transmission between stations, but it can interconnect any number of stations that are included within the antenna beams of the satellite rather than simply the two ends of the microwave link. Computer Crime Computer crime is defined as any crime involving a computer accomplished through the use or knowledge of computer technology. Computers are objects of crime when they or their c ...

... Although it consumes physical space and requires proper care, non-acidic paper printouts can hold information for centuries. If long-term storage is not of prime concern, magnetic medium can retain tremendous amounts of data and consume less space than a single piece of paper. The magnetic technology used for computer data storage is the same technology used in the various forms of magnetic tape from audiocassette to videocassette recorders. One of the first computer storage devices was the magnetic tape drive. Magnetic tape is a sequential data storage medium. To read data, a tape drive must wind through th ...

... whether they are ordinary natural or artificial the photon waves will not be traveling together because they are not being emitted at exactly the same moment but instead at random short bursts. Even if the light is of a single frequency that statement would also be true. A laser is useful because it produces light that is not only of essentially a single frequency but also coherent, with the light waves all moving along in unison. Lasers consist of several components. A few of the many things that the so-called active medium might consist of are, atoms of a gas, molecules in a liquid, and ions in a crystal. ...

... dial. A telephone can be separated into two main categories: there is the tone (touch tone) or the older rotary dial (pulse) telephones. Then you can divide those into other categories such as business line (multi -- line) or home line (single line). You can also have many other types of phones: there are those that hang on the wall, on the desk, etc. THE HANDSET No matter what kind of telephone you own, there has to be some device that allows you to talk to and listen to. This device is called the handset. The handset is usually made out of plastic and inside it are two main components: the transmitter and t ...

... Database are discussed; tips on learning the languages are offered; and a list of publishers' addresses is provided. One way of programming is rapid application development (RAD) has tremendous powers, but it is not without its limits. The two basic advantages RAD tools promise over traditional programming are shorter, more flexible development cycle and the fact that applications can be developed by a reasonably sophisticated end user. The main disadvantage is that RAD tools often require code to be written, which will result in most developers probably having to learn to program using the underlying programming ...

... when struck with the proper digital stimulus will react in the exact same way each time (Rosch,37). More practically a microprocessor is multitudinous transistors squeezed onto as small a piece of silicon as possible to do math problems as fast as possible. Microprocessors are made of many smaller components which all work together to make the chip work. A really good analogy for the way the inner workings of a chip operate can be found in How Microprocessors Work. In their book, Wyant and Hammerstrom describe a microprocessor as a factory and all of the inner workings of the chip as the various parts of a factory ...

... ago, Baxter Phillip sees the Internet-induced level playing field as myth. Net commerce still slants against the little guy, says the vice president of the Chicago-area-based Phillip's 1-800-FLORALS, and he faces a steeper incline all the time. "The Internet is like a huge mall in the middle of the Sahara desert," Phillip says. "Once you get there, which is the first hurdle, all the competitors are lined up together, one next to the other. So where do you go? You gravitate towards the brand names you already know -- the biggies." While Web site affordability has made it easier for companies like Phillip's to estab ...

... What about the computer programmer? One error in the program could mean death for a patient. One job that I'm sure many people would give to a computer if they had the chance would be a lawyer. This eliminates the problem that occurs when someone with money is in trouble. They buy the best lawyer money can buy, but the person without any money cannot afford the great lawyers the other guy has. With this system, one single lawyer program could be provided to everyone so that the process of dispensing justice is much more fair. What about a judge and jury? Could a computer replace them? Is it right for a comput ...

... Only the wages of college graduates are up. Of the fastest growing technical jobs, software engineering tops the list. Carnegie Mellon University reports, "recruitment of it's software engineering students is up this year by over 20%." All engineering jobs are paying well, proving that highly skilled labor is what employers want! "There is clear evidence that the supply of workers in the [unskilled labor] categories already exceeds the demand for their services," says L. Mishel, Research Director of Welfare Reform Network. In view of these facts, I wonder if these trends are good or bad for society. "The dang ...

... can cause radar signals that are sent out by a radar unit by having the signals hit a part or all of the aircraft and what happens to those signals is that they either pass right through the aircraft or they are reflected towards another direction and this is caused because of the Radar Absorbent Material (RAM) and in this way the aircraft can be virtually undetectable to radar. The Development of Stealth Technology This Technology was cloaked in a veil of secrecy for almost two decades, but this entirely new family of aircraft has recently been announced to the public but the United States Department of Defence. ...
