... depend on the convenience, speed, accuracy, and reliability that computers have become known for. But not all companies are large enough to benefit from the use of computers. First a company must research the impact a computer will have on keeping track of its accounts. Then they must choose the correct hardware and software that's best for their needs, while at the same time making themselves familiar with the new enhancements that increase productivity. Finally, the company must allow time for installation and training. When looking at the need to change from a manual accounting system to a computer ...

... of different places such as the federal government, state, or the city through which the system runs. Different government agencies have jurisdiction over the modes. These agencies focus on maintaining and improving safety of each system. The individual states also have certain obligations to the operation and regulation of the different modes of transportation. Each mode is made up of primary subsystems. The subsystems of railroad transportation include freight trains and passenger trains. Freight trains are used to transport goods and materials between cities while passenger trains are used to transport ...

... government every designed, and as you will see the ability that GPS has for everyone. provides two levels of service, the Standard Positioning Service, and the Precise Positioning Service. " The Standard Positioning Service or SPS is a positioning and time service which is available to all GPS users on a continuous, worldwide basis with no direct charge." (Tycho) The SPS is provided on the L1 frequency, which then will code a navigational message. The SPS accuracy is 100-meter horizontal, 156-meter vertical, and 340 nanoseconds time, and in total the SPS is ninety-five percent accurate. (Utexas) The Department ...

... The Arpanet was created by the Pentagon in the late 1969 as a network for academic and defense researchers. In 1983, the National Science Foundation took over the management of the Internet. Now the Internet is growing faster than any other telecommunications system ever built. It is estimated that in three years, the system will be used by over 100 million people (Cooke 61). Since the World Wide Web (WWW or W3) became popular through point-and-click programs that made it easier for non-technical people to use the Internet, over 21,000 businesses and corporations have become accessible through the Internet (Baig ...

... is controlled by a computer, a computer will read and recognize your driving patterns and adjusts how and when the transmission should shift from gear-to-gear so that you, as the driver, will get maximum performance from your car. In some vehicles, a computer will adjust how high the car rides from the ground. It lowers the car at highway speeds to make it more aerodynamic which will give you better gas mileage and makes the car easier to handle at these high speeds. The latest computer is an on-board navigational computer that will direct the driver into using the fastest and most efficient way to get to ...

... effect on society as well. As John McCarthy, Professor of Computer Science at Stanford University, speculated in 1966: "The computer gives signs of becoming the contemporary counterpart of the steam engine that brought on the industrial revolution - one that is still gathering momentum and whose true nature had yet to be seen." Today's applications of computers are vast. They are used to run ordinary household appliances such as televisions and microwaves, to being tools in the workplaces through word processing, spreadsheets, and graphics software, to running monumental tasks such as being the heart and so ...

... two people communicating on a CB radio use the same frequency, so only one person can talk at a time. A cell phone is a duplex device, so it uses one frequency for talking, and a second separate frequency for listening (Dang). A CB radio has 40 channels. A cell phone can communicate on 1,664 channels. Cell phones also operate within cells and they can switch cells as they move around. Cells give cell phones incredible range. A walkie-talkie can transmit perhaps a mile. A CB radio, because it has much higher power, can transmit perhaps 5 miles. Someone using a cell phone, on the other hand, can drive clear across a c ...

... to typing too much on the keyboard. This paper will be focusing on the principals of ergonomics in the computer workstation. According to the Board of Certification for Professional Ergonomists (BCPE), the definition of ergonomics "is a body of knowledge about human abilities, human limitations and human characteristics that are relevant to design. Ergonomic design is the application of this body of knowledge to the design of tools, machines, systems, tasks, jobs, and environments for safe, comfortable and effective human use."(BCPE, 1993) In the average computer workstation, employees are prone to over a ...

... These materials are known as catalysts. A catalyst is an element which although causing a reaction to occur, does not change at all during the reaction. This is the idea behind a catalytic converter. The carbon monoxide gas and hydrocarbons emitted from the engine will travel along the exhaust system until they reach they catalytic converter. There it comes into contact with the described catalyst. This forces a reaction between the carbon monoxide and hydrocarbons with the oxygen inside the converter creating products of carbon dioxide and water vapor. The reaction which occurs inside the converter is ...

... because buying a computer can be confusing does not mean one should throw up his hands and put himself at the mercy of some salesman who may not know much more than he does. If one would follow a few basic guidelines, he could be assured of making a wise purchase decision. A computer has only one purpose; to run programs. Some programs require more computing power than others. In order to figure out how powerful a computer the consumer needs, therefore, a person must first determine which programs he wants to run. For many buyers, this creates a problem. They cannot buy a computer until they know what they ...
