.... Collectively, educational establishments, community organizations or state and municipal groups, operate approximately 350 member stations. All public television stations highlight the importance of illuminating cultural and educational programming, as well as distinguished programs on nature, science, and public affairs. In PBS: Behind the Screen, Laurence Tarvik depicts this unique organisation as "a $5 million appropriation" which over time, became a "multi-billion worldwide multi-media empire" (xvii). Over four decades, PBS has become a leader in using technology to further its educational objective, such as, closed captioni .....

.... amplifier. Acoustic compensation can be carried out in a hearing aid microphone. Most hearing aids today utilize omnidirectional microphones, which pick up sound equally from all directions. This may be beneficial and practical in some cases, as in the completely in the canal (CIC) aid. The CIC aid uses the natural funneling of the auricle in order to focus sound directly into the instrument. Behind-the-ear (BTE) and full concha in-the-ear (ITE) aids lose this anatomical feature, and may benefit from a directional microphone. “The purpose of using a directional microphone is to focus its sensitivity toward the front of t .....

.... 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 us .....

.... 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 diplom .....

.... in turn, involves the use of more math models. In order to be capable of completing the above tasks, a system analyst must continue education beyond high school. The post-secondary education required for a system analyst can be found only at a four- year institution. A student looking to become a system analyst must concentrate on the science and math courses offered by such an institute. Employers look for people who possess a Bachelor of Science degree in one of the following areas: computer engineering, computer information systems, computer science, data processing, information science, and technical engineering (Wisco .....

.... conferencing and speaker phones. Massive oversea trade deals are made overseas with the aids of phones, fax, and the Internet. Without these forms of communication we would have to take a plane across the ocean just to talk to someone on the other side of the pond. Types Of Communication Systems 1. A data communication system involves the use of computers in processing information. These systems are a part of any technical communication process. Data communication systems have evolved from the abacus(3000 B.C.) To the high-tech computer chips of today. The only thing similar about the two things is what they are used for; .....

.... most hardware makes it easy for someone to upgrade their computer. The desktop is designed so the user has point and click access to all their open and closed programs. Utilizing the 32 bit programing it was written with, users are able to work with more than one program at a time and move information between programs. This gives the user the freedom they need to begin to explore the world of computing without having to learn all the “ computer stuff”. Today everyone wants the fastest computer with the best monitor and fastest modem this was an interrupt address nightmare until Windows 95 was developed. People didn't kn .....

.... "Heinkel He 178" came into a few operational squadrons in the German, British, and the American air forces towards the end of World War II. These jets finally helped the allies to win the war against the axis powers(Smith 23-27). A later development in the jet industry was the overcoming of the sound barrier and establishing normal operations up to and beyond twice the speed of sound. Also air force bombers and transports were able to reach and cruise at supersonic speeds(Silverstein 56-70). In the late 1950's civil transcontinental jet services started with the Comet 4 and the Boeing 707. In the mid 1960's all major jet manu .....

.... Internet has always been a battlefield between phreaks and administrators. The Internet hasn't always been a public forum. In fact, the Internet has been around for years. The Internet is just a new fad ("The More I Learn" A1). The Internet originally began as DARPANET, a government-created network, which was designed for defense communications. The Net structure is such that it could survive a nuclear war ("Internet History"). The creation of the Net can not be blamed for the existence of hackers though, hackers are older than the Net itself, but the Net is the largest 'hacker haven' today (Spencer, "Hacking McDonalds" 6). .....
