... "digital calculating machine". It could only 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 "punch cards". His inventions were failures for the most part because of the lack of precision machining techniques used at the time ...

... increase inherent in any basic 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 the listener, thereby attenuati ...

... expanded between the 1950s and the 1970s, the focus of computer science broadened to include simplifying the use of computers through programming languages—artificial languages used to program computers, and operating systems—computer programs that provide a useful interface between a computer and a user. During this time, computer scientists were also experimenting with new applications and computer designs, creating the first computer networks, and exploring relationships between computation and thought. In the 1970s, computer chip manufacturers began to mass-produce microprocessors—the electronic circuitry that serves as the main information processing center in a computer ...

... the security code to access them. Thanks to Internet technology, companies and other types of organizations are able to keep all of their information organized and easily accessible with a click of a button. The Internet, how has it changed the world around us? Government, education, business is all wrapping around it. Is this because of all of the information on it, simplicity or is it the quickness, with a simple point and click and the information appears on the screen. The first intention of the Web, as it is referred to, was not to create a sea of web servers and surfers. The Department of Defense created it for it's own use, to keep contact with all of the locations thro ...

... States in 1986, according to the National Center for Computer Crime Data in Santa Cruz, Calif. By 1989, that number jumped to 500 prosecutions. that year cost businesses and banks - and, ultimately, consumers - about $500 million. "As the use of computers has increased, so has their criminal misuse" (Bowers 54:g13). Computers are used to obtain credit card numbers, which are then used to order thousands of dollars worth of whatever the hackers want. "In recent years, individual outlaws and entire "gangs" have broken into computers all over the U.S., using their wits and wiles to pilfer and destroy data"(Behar p62). In a case of a 14 year old high school freshman who was convicted ...

... Virus Effects Attack specific body cells' Modify the genetic information of a cell other than previous one. It performs tasks. New viruses grow in the infected cell itself. An infected program may not exhibit symptoms for a while. Not all cells with which the virus contact are infected. Viruses can mutate and thus cannot clearly be diagnosed. Infected cells aren't infected more than once by the same cell. Computer Virus Effects Attack specific programs (*.com,*.exe) Manipulate the program: The infected program produces virus programs. The infected program can work without error for a long time. Program can be made immune against certain viruses. Virus program can modify themselve ...

... Dennis Ritchie began to develop their own single-user, multi-tasking small operating system and they chose the name UNIX. Their initial goal was simply to operate their DEC PDP machines more effectively. In 1971, UNIX became multi-user and multi-tasking, but it was still just being developed by a small group of programmers who were trying to take advantage of the machines they had at hand. (In other words, this operating system that they were developing did not run on any machine made by Bell!) In 1973, Dennis Ritchie rewrote the UNIX operating system in C (a language he had developed.) And in 1975, the portability of the C programming language was used to "port" UNIX to a wide variety of ...

... only a matter of time, hard work, and some luck before molecular electronics start having a noticeable impact." Molecular electronics is so named because it uses molecules to act as the "wires" and "switches" of computer chips. Wires, may someday be replaced by polymers that conduct electricity, such as polyacetylene and polyphenylenesulfide. Another candidate might be organometallic compounds such as porphyrins and phthalocyanines which also conduct electricity. When crystallized, these flat molecules stack like pancakes, and metal ions in their centers line up with one another to form a one-dimensional wire. Many organic molecules can exist in two distinct stable states that differ ...

... simple animation scripts. Interaction with the virtual world, at least with near real time control of the viewpoint, in my opinion, is a critical test for a 'virtual reality'. Some people object to the term "Virtual Reality", saying it is an oxymoron. Other terms that have been used are Synthetic Environments, Cyberspace, Artificial Reality, Simulator Technology, etc. VR is the most common and sexiest. It has caught the attention of the media. The applications being developed for VR run a wide spectrum, from games to architectural and business planning. Many applications are worlds that are very similar to our own, like CAD or architectural modeling. Some applications provide ways of view ...

... in the comforts of home with less distraction. The software for PCs is extensive and the students can obtain all the information he/she needs for an assignment. The time that was spent running to the library has been cut by about ninety percent. This is due to the new and ever improving software that is produced for personal computers. Secondly, the computer has become a strong teaching tool in many schools across the nation and maybe the world. Since the introduction of computers in the classrooms, students have shown a progression of their skills in reading and mathematics. There are many tutorial software programs that are readily available for the students who are having proble ...
