.... add numbers and they had to be entered by turning dials. It was designed to help Pascal's father who was a tax collector (Soma, 32). In the early 1800's, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered and could store up to 1000 50-digit numbers. Built in to his machine were operations that included everything a modern general-purpose computer would need. It was programmed by— and stored data on—cards with holes punched in them, appropriately called "punchcards". His inventions were failures for the most part because of the lack of precision machining techniques u .....

.... as much power as a large engine but the engine life would be reduced due to the stress. The advantage of small displacement engines is that they are fuel efficiency and weigh less than larger engines. The small displacement engine can also be modified to gain more power but the engine life is also reduced. The larger displacement is stronger and it can handle more modification but it still cannot accelerate as fast as a smaller engine and it consumes a larger amount of fuel. Both low displacement and high displacement engine has its advantages. An analogy that demonstrates this is a long distance runner and a sprinter. When .....

.... alternate reality, however, you need to find ways to create the illusion of reality with a piece of machinery known as the computer. This is done with several computer-user interfaces used to simulate the senses. Among these, are stereoscopic glasses to make the simulated world look real, a 3D auditory display to give depth to sound, sensor lined gloves to simulate tactile feedback, and head- trackers to follow the orientation of the head. Since the technology is fairly young, these interfaces have not been perfected, making for a somewhat cartoonish simulated reality. Stereoscopic vision is p .....

.... thing about the multimedia boom, is that so many moguls are spending such vast sums to develop digital technologies, for the delivering of programs and services which are still largely hypothetical. So what is behind such grand prophecies? Primarily, two technological advances known as digitization (including digital compression), and fibre optics. Both are indispensable to the high-speed networks that will deliver dynamic new services to homes and offices. Digitization means translating information, either video, audio, or text, into ones and zeros, which make it easier to send, store, and manipulate. Compression squeezes .....

.... free access to copyrighted music. There are numerous arguments originating from all sides of the debate. Many of these are mutually exclusive and, therefore, cannot all be substantiated. McDougall (2000) published an article online, in which he summates the main arguments listed below: • Copying is fair use • Copying is theft • Music wants to be free • Napster users buy more CDs • Music companies make too much money • Music companies will make more money with Internet distribution • Musicians can’t make money with Internet distribution • Musicians will make more money with Internet distribution Withi .....

.... By itself the telegraph could express only two states, on or off. This limitation was eliminated by the fact that it was the duration of the connection that determined the dot and dash from each other being short and long respectively. From these combinations of dots and dashes the Morse code was formed. The code included all the letters of the English alphabet, all the numbers and several punctuation marks. A variation to the telegraph was a receiving module that Morse had invented. The module consisted of a mechanically operated pencil and a roll of paper. When a message was received the pencil would draw the correspo .....

.... 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 what CAM (Computer Aided Manufacturing) is, and how it is used in the industry. CAM software is generally used for the creation of N/C (Numerical Controlled) programs. N/C programs control machines that make parts, such as rocket parts, car parts, and airplane parts. .....

.... doors for our society. Now anyone can use the Internet to communicate with anybody else in the world a lot faster and cheaper. Cellular phones have also appeared recently in the electronic world. These devices allow a person to be reached from practically anywhere. With cellular phones a person can, from then on, be in communication with the world no matter where they go. For the next generation, electronics will certainly offer new yet simpler technology available to the general public. Home addresses and phone numbers will be replaced with Internet addresses. Business people will be able to have access to tools such as v .....

.... Combustion Engine (RCE) as invented by Felix Wankel and developed with Walter Froede of NSU differs from a Piston Engine in four fundamental ways: The RCE Rotor supercedes the piston engine's piston. The RCE Eccentric Shaft [gloss] supercedes the piston engine's crankshaft and connecting rods. The RCE Peripheral Housing [gloss] supercedes the piston engine's cylinder. Intake and Exhaust Ports [gloss] in the housings eliminate valves, camshafts, cams, lifter rods, and timing belts. See also porting. The RCE has considerable advantages over the conventional piston engine. The RCE Rotor Moves Inside an Epitrochoid Cu .....

.... The same features that make the Internet so appealing such as interactivity, versatile communication, and customizability also make it an ideal way for someone to keep a careful watch on the user without them being aware of it (Lemmons 1). It may not seem like it but it is completely possible to build a personal profile on someone just by tracking them in cyperspace. Every action a person does while logged onto the Internet is recorded somewhere (Boyan, Codel, and Parekh 3). An individual's personal security is the major issue surrounding the Internet. If a person cannot be secure and have privacy on the Internet, the wh .....
