.... model, a series of small and large sheets connected to one another like a quilt blanket, displaying the shape the designer intended. Lastly, is the solid model. It is represented in the computer as solid shape, as if it were, for example a solid piece of steel All data concerning its shape is known by the computer software, and can be manipulated in more of an automated way rather than every surface or every wire frame requiring individual shaping (Unigraphics 1-1). CAD/CAM software also creates N/C Programs for manufacturing. But, first let’s define wha .....

.... 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) real name, real handle, or real phone number on any sys .....

.... is stimulated, as it falls back to a lower energy state, to emit a second photon of the same frequency, in phase with and in the same direction as the bombarding photon. This process is called stimulated emission. The bombarding photon of the emitted photon may then strike other excited atoms, stimulating further emission of photons, all of the same frequency and phase. This process produces a sudden burst of coherent radiation as all the atoms discharge in a rapid chain reaction. The light beam produces is usually pencil thin and maintains its size and direct .....

.... 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 .....

.... has been important in reducing the cost of fiber systems by allowing a single laser to be shared among multiple receivers. The smallest, final span of cable, called the drop, is the portion of the network that runs between the last place where the signal is split to the home of the subscriber. at this time, the drop portion of the network is exclusively coaxial cable; however, cable operators and equipment vendors alike are exploring ways to make fiber an economic alternative to coax. Cable TV operators are evaluating a variety of new services, among the most .....

.... a data set culled from CU channels of communication this paper provides an ethnographic account of computer underground organization. It is concluded that despite the widespread social network of the computer underground, it is organized primarily on the level of colleagues, with only small groups approaching peer relationships. Certification: In accordance with departmental and Graduate School policies, this thesis is accepted in partial fulfillment of degree requirements. ______________________ .....

.... to revolutionize computer design and performance," said Robert R. Birge, a professor of chemistry, Carnegie- Mellon University, Pittsburgh. "Now it's only a matter of time, hard work, and some luck before molecular electronics start having a noticeable impact." Molecular electronics is so named because it uses molecules to act as the "wires" and "switches" of computer chips. Wires, may someday be replaced by polymers that conduct electricity, such as polyacetylene and polyphenylenesulfide. Another candidate might be organometallic compounds such as porphyrin .....

.... can store databases which could contain information that is kept by police for easier records or you could just use it for your own family history. The basic structure of a computer is a keyboard, a moniter, a and case which holds all the componets to make a computer run like a Hard drive, a Motherboard, and a Video card. There are many other additions you can make to this such as a Modem, a Joystick, and a Mouse. The personal computer was developed during the year 1945 by the Americans to help them decode enemy secret codes during the Second World War. At this .....
