... the power of the Internet. For many businesses the Internet is becoming integral to their operations. All users of the Internet have the ability to send and receive data: messages, notes, letters, documents, pictures, video, sound- almost any form of communication, as effortlessly as making a phone call. It is easy to understand why the Internet is rapidly becoming the medium of choice for business. Using the mouse on your computer, the easy point-and-click interface gives you access to electronic mail for sending and receiving data, and file transfer for copying files from one computer to another. Telnet services allow you to establish connections with syst ...

... into the house. Mass production and other job opportunities brought many people from the suburbs and farms into the city. We can now have forms of electricity directed into our houses for heating and light. Humans are more reliant on technology then ever before. All of these technological advances sound great, however, there is a negative effect to all this technology. Technology can serve to actually harm humans rather then help them. Competition between companies or even cities can sometimes make lives for humans even worse. Take for example when a city builds better and more roads to attract tourists. This actually creates more traffic, not less. Te ...

Over the years many new types of keyboard have been thought up these are mostly more ergonomically designed than there older counter parts this is done in order to reduce R.S.I a problem that effects a lot of typists One of the most interesting keyboard is a device called a data hand this will take a combination of hand movement and clicks and convert them in to working commands. Another type of keyboard is the virtual keyboard this remov ...

... under which they should normally be kept. For example: the actuall magnetic disk inside the hard cover of the disk must NEVER be touched, the magnetic disk inside, must be protected by the metallic sliding shield, the disk must always be within the temperature of 50° to 140° Fahrenheit and the disk must never be bought near a magnet! (3M Diskettes) There are many such hazards to computer disks. Problems caused by magnets are very common. A floppy can be damaged unknowingly if it is kept near a magnet, that may be in the open or inside any device, such as a speaker phone in computer speakers or stereo or a telephone. And becuase of the common use of magnets ...

... acts. Examples of these types of crimes are complex embezzlements that might occur over long periods of time, or when a computer operator uses a computer to steal or alter valuable information from an employer. Variety and Extent Since the first cases were reported in 1958, computers have been used for most kinds of crime, including fraud, theft, embezzlement, burglary, sabotage, espionage, murder, and forgery. One study of 1,500 computer crimes established that most of them were committed by trusted computer users within businesses i.e. persons with the requisite skills, knowledge, access, and resources. Much of known computer crime has consisted of enteri ...

... errors, a system can be designed in which the Liveware-Hardware interface can promote safety and reduce mishap frequency. II. The History Of Human Factors in Cockpit Design The history of cockpit design can be traced as far back as the first balloon flights, where a barometer was used to measure altitude. The Wright brothers incorporated a string attached to the aircraft to indicate slips and skids (Hawkins, 241). However, the first real efforts towards human factors implementation in cockpit design began in the early 1930's. During this time, the United States Postal Service began flying aircraft in all-weather missions (Kane, 4:9). The greater relian ...

... Engine. The plans for this engine required an identical decimal computer operating on numbers of 50 decimal digits (or words) and having a storage capacity (memory) of 1,000 such digits. The machine was supposed to operate automatically, by steam power, and require only one person there. Babbage's computers were never finished. After Babbage, there was a temporary loss of interest in automatic digital computers. A strong need thus developed for a machine that could rapidly perform many repetitive calculations. ------------------------------------------------------------------------ Use of Punched Cards by Hollerith A step towards automated comput ...

... rifle for all American troops and was later fitted to be fully automatic. The bazooka, invented in 1941 by American scientists, was first used in the invasion of North Africa in war and proved to be excellent anti-tank warfare. It was also during this time that bullets were upgraded from the pinfire type to the rimfire type. The rimfire type proved to be more precise and damaging because of its finer texture and cartridge case. Miscellaneous advancements include chemical agent weapons (i.e. nerve gas, mustard gas), flame-throwers, improved hand grenades, and other minor adjustments to firearms in general. The Americans during World War II also impr ...

... to "programming" rules that the user must memorize, all ordinary arithmetic operations can be performed (Soma, 14). The next innovation in computers took place in 1694 when Blaise Pascal invented the first Òdigital calculating machineÓ. It could only add numbers and they had to be entered by turning dials. It was designed to help PascalÕs father who was a tax collector (Soma, 32). In the early 1800Õs, 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 ...

... stones, but that is a bad mistake. Go to the side with the one black (a setup move so the computer cannot capitalize when you turn 5 black stones white, and the computer your seven whites black. Always play within your set "square". If you had on the bottom row 3 white, and on the second row 2 blacks, you would only play within that designated square, which is 3 x 3 stones. (see diagram.) This ensures that the computer can only play one stone past the square at any time, which will help you in predicting where the computer will move and a basic strategy. Always try to keep yourself to one move to win (if you could have two moves in a row, you wou ...
