.... Diodes). Each of these methods create a highly focused beam of light that is cycled on and off at very high speeds. Computers at the transmitting end convert data or voice into "bits" of information. The information is then sent through the fiber by the presence, or lack, of light. So, all of the data is sent light pulses. Computers on the receiving end convert the light back into data or voice, so it can be used. All of this seems to be a very "modern" concept, and the technology we use is. The concept though, was the idea of Alexander Graham Bell in the late 1800's. He just didn't have a dependable light source .....

.... must be able to generate enough wattage for the SPL (sound pressure level) of the higher frequencies to be heard clear in a space the size of the AEROSTAR. Pre-amp Out RCA Jacks To allow for low-level amplification without using an in-line power reducer, the head unit will require low level pre-amplification output jacks. Head units ordinarily come with either front and rear, or just rear RCA jacks. This situation will only require rear jacks since the head unit produces enough wattage sufficient for the front speakers. The sub-woofer system will be powered by an additional external amplifier by using these jac .....

.... about navigation. Since prehistoric times, people have been trying to figure out a reliable way to tell where they are, to help guide them to where they are going, and to get them back home again. Cavemen probably used stones and twigs to mark a trail when they set out hunting for food. The earliest mariners followed the coast closely to keep from getting lost. When navigators first sailed into the open ocean, they discovered they could chart their course by following the stars. The ancient Phoenicians used the North Star to journey from Egypt and Crete. According to Homer, the goddess Athena told Odysseus to "keep the G .....

.... are located along the coasts. Ransome was banking on that an electric mowing machine would fit that need. It has been slow to catch on as of late. It's benefits are an almost quiet no noise machine. (Beard 302). Many country club members would become outraged when the superintendents would send out the greensmowers daily at 6:00 A.M. The diesel and gasoline powered engines are noisy, and would wake up many members that live along the golf course. The second benefit is no cost of gasoline or oil, and therefore no chance of a petroleum leak or spill. There downfall lies in there initial cost,"$15,000 for a gasoline triplex m .....

.... warehousing and distribution, customers and suppliers, sales and marketing activities, financial management and the overall control of the enterprise. At one extreme, a Computer-Integrated Manufacturing process may be fully automated, with computers (and robots) controlling the entire production process with minimal human intervention. However, CIM is typically employed at a level short of total integration. Many manufacturers who are leaders in CIM typically have concentrated their efforts in two areas: Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM). Computer-Aided Design (CAD) applies the computer to the .....

.... number one in this U.S. market. Apple Macintosh computers account for 60% of the 5.9 million machines in U.S. schools for the 1995-96 school year. Only 29% of schools use the Microsoft/Intel platform, and DOS only accounts for a measly 11%. Also it was reported that 18.4% of 4 year college students own the Macintosh. 55% of college students own a computer, and Apple's in the lead for that market too! The reason Apple says for this continued success is the Mac's ease of use. There is no doubt that the Macintosh is the easiest computer around. The scrolling menu bar is the first example. If a Macintosh menu is too long to fit on .....

.... from city to city, and base to base. The network was designed to function when parts of it were destroyed. The network could not have a center because it would be a primary target for enemies. In 1969, ARPANET was created, named after its original Pentagon sponsor. There were four supercomputer stations, called nodes, on this high speed network. ARPANET grew during the 1970's as more and more supercomputer stations were added. The users of ARPANET had changed the high speed network to an electronic post office. Scientists and researchers used ARPANET to collaborate on projects and to trade notes. Eventually, people used .....

.... message and displays numbers that change every few minutes. These numbers make the password one needs for the next few minutes in order to access the computer. This password method is somewhat new. It is also better, for the previous password method is not totally fool proof. This is because the passwords are stored in the computer and if a computer literate person was to access this information, they could get into a computer and enter it looking as if they were someone else for they have obtained someone else's password. In the future when technology increasingly gets better there are possibilities that a computer could use .....

.... and more than one billion pieces of electronic mail are passed through the world's networks daily. It is the age of the computer network, the largest of which is known as the InterNet. A complex web of communications inter-linking millions of computers together -- and this number is at least doubling every year. The computer was originally designed as a scientific and mathematical tool, to aid in performing intense and precise calculations. However, from the large, sixty square foot ENIAC (Electronical Numerical Integrator and Calculator) of 1946, to the three square foot IBM PC of today, their uses have mutated and expanded .....

.... computer only generates information, without the authority to change the process in which it functions. The computer is only following instructions that “make it possible for a sequence of operations to be repeated over and over again until some condition is fulfilled, but in doing so to obey, not to fresh instructions on each repetition, but the same ones over and over again”(p.438). He then asserts that digital computers can be built and have been built that “in fact mimic the actions of the human computer very closely”(p.438). He also further proposes that a computer with an infinite capacity to store information c .....
