... bandwidth or information-carrying capacity • small physical size • relative low cost The speed at which information can be moved through the fiber optic cable is also an important advantage. AT&T established an experimental fiber optic system that moves digital information at a speed of 8 gigabits (8 billion bits) per second over a 68-mile stretch of repeaterless fiber optic cable. One gigabit per second is fast enough to support 15,000 voice circuits. The growth of fiber optics has other features that make it valuable to future telecommunications. Since the light wave transmission is enclosed, it is not bothered by atmospheric conditions that affect wireless systems. It a ...

... a control unit, and output devices. Most of the actions of the analytical engine were to be done through the use of punched cards. Even though Babbage worked on the analytical engine for nearly 40 years, he never actually made a working machine. In 1889 Herman Hollerith, an American inventor, patented a calculating machine that counted, collated, and sorted information stored on punched cards. His machine was first used to help sort statistical information for the 1890 United States census. In 1896 Hollerith founded the Tabulating Machine Company to produce similar machines. In 1924, the company changed its name to International Business Machines Corporation. IBM made punch-card of ...

... for their services," says L. Mishel, Research Director of Welfare Reform Network. In view of these facts, I wonder if these trends are good or bad for society. "The danger of the information age is that while in the short run it may be cheaper to replace workers with technology, in the long run it is potentially self-destructive because there will not be enough purchasing power to grow the economy," M. B. Zuckerman. My feeling is that the trend from unskilled labor to highly technical, skilled labor is a good one! But, political action must be taken to ensure that this societal evolution is beneficial to all of us. "Back in 1970, a high school diploma could still be a ticket to the middl ...

... 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 reliance on instrumentation raised the question of where to put each display and control. However, not much attention was being focused on this area as engineers cared more about getting the instrument in the cockpit, than about h ...

... would then find its way to ISD (Information Services Department) where it would be assigned to a programmer analyst who would do an in-depth analysis with the help of the ASU analyst and define the requirements for the automation project. The programming would begin and soon, a new program was created and deployed. The requests and problems soon began to multiply and expand until it was like a virtual snowstorm of requests, too many for one small unit to keep under control. Help arrived around 1990 in the form of the Automation Project Administrator – the first of the Automation Coordination Specialists gathered together to relieve some of the burden falling on ASU. The Automation Proj ...

... he chooses. It might be the company library, or a common area under a bright window. It could even be the dining room or Student Union, which houses punching bags, televisions and a pool table. Wherever he goes, a network forwards mail and phone pages to him and a computer routes calls, faxes and E-mail messages to his assigned extension. He simply logs onto the firm's computer system and accesses his security-protected files. He is not tethered to a specific work area nor forced to function in any predefined way. Joe Smith spends mornings, and even sometimes an entire day, connected from home via sophisticated voicemail and E-mail systems, as well as a pager. His work is process and task ...

... network that linked 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 ARPANET for leisure activities such as ch ...

... Children are less likely to be killed in a crash if they are in the back seat. If someone must put a child in the front seat, they may want to have an on/off switch for the airbag installed on the passenger side. On/off switches are used to prevent the airbag from going off in an accident, but they aren’t recommended for most people. You only need an airbag switch on the driver’s side if your legs are too short to reach the pedals and have your torso 10 inches away from the steering wheel. Passenger side switches should only be used if you always have to have a small child or infant sit in the front seat because they have a medical problem and need to be watched constantly. Airbag swit ...

... the weapons used in war has been an issue since the beginning. Nowadays, the military has spent billions of dollars perfecting stealth technology to allow planes to slip past enemy lines undetected. The technology involved in a complicated system such as these fighter planes is immense. The older planes are packed with high tech gear such as micro processors, laser guiding devices, electromagnetic jammers and infrared sensors. With newer planes, the airforce is experimenting with a virtual reality helmet that projects a cartoon like image of the battlefield for the pilot, with flashing symbols for enemy planes. What is more, if a pilot passes out for various reasons such as the "G" force ...

... robot gets a new assignment, it will need new instructions, but its basic structure will not change (except maybe a new mechanical hand). By "multifunctional" they mean a robot is the mechanical counter part of a computer that can handle various problems without any major hardware modifications. The only thing that changes when a robot is reassigned is its program of instructions. In modern robots, programmable microprocessors control all the robot's movements and actions. Robots can be taught by using a teaching mode. An operator moves the robot's hand through all of the desired motions manually with his own hand. When the robot is activated, it will repeat those same motions ove ...
