... of speakers. Reproduction of higher frequency sounds (i.e. violin, flute) as well as lower frequency sounds (bass violin, tuba) require more power to be heard at the same level as a midrange sound (voice, trumpet). The internal amplifier in the head unit must be able to generate enough wattage for the SPL (sound pressure level) of the higher frequencies to be heard clear in a space the size of the AEROSTAR. Pre-amp Out RCA Jacks To allow for low-level amplification without using an in-line power reducer, the head unit will require low level pre-amplification output jacks. Head units ordinarily come with either front and rear, or just rear RCA jacks. T ...

... data in the computer. For example, send a flood of coffee toward a personal computer. The hard disk of the computer could be endangered by the flood of coffee. Besides, human caretaker of computer system can cause as much as harm as any physical hazard. For example, a cashier in a bank can transfer some money from one of his customer's account to his own account. Nonetheless, the most dangerous thief are not those who work with computer every day, but youthful amateurs who experiment at night --- the hackers. The term "hacker "may have originated at M.I.T. as students' jargon for classmates who labored nights in the computer lab. In the beginning, hackers are not ...

... the equalizer settings yourself, Winamp has hundreds of preset settings which are categorized by music type. Examples of this include Jazz, Rock, Reggae, and many more. Winamp users even have the ability to create and save song-specific pre-amplifier and equalizer settings. Another important factor in choosing a music program for your computer is customizable features. Winamp meets this criterion well. The ability to customize your music player makes the program easier to use. The user has the ability to make a “Play list” from the music files that are stored on the hard drive of the user’s computer. Play lists are easy to load and are not difficult to cr ...

... as a big concern, there is a greater issue at hand. Since censorship encompasses all forms of expression, censoring the Internet would hurt many people. Since the Internet is an international community, we must view it as pertaining to other countries; not just the United States. Not all countries have the privilege of living in a democracy and under the Bill of Rights. As a result, the Internet as brought newfound freedom to most people who are oppressed by tyrannical governments, or those that disagree with governments but are not allowed to express it. People in these countries can now be exposed to views that they haven't thought about, or views that they ...

... changes. PC users came from using MS-DOS and Windows 3.1, to Windows 95, a whole new operating system. Computer speeds have taken a huge increase as well, in 1995 when a normal computer was a 486 computer running at 33 MHz, to 1997 where a blazing fast Pentium (AKA 586) running at 200 MHz plus. The next generation of processors is slated to come out this year as well, being the next CPU from Intel, code named Merced, running at 233 MHz, and up. Another major innovation has been the Internet. This is a massive change to not only the computer world, but to the entire world as well. The Internet has many different facets, ranging from newsgroups, where you can ...

... it looks like it has sprung up overnight, the vision of free-minded hackers, it was born in the ‘Defense Department Cold War’ projects of the 1950s. The US Government owns the Internet and has the responsibility and right to decide who uses it and how it is used. The government HAS to have control on what information people are able to get from its agencies. This information is not lawfully available through the mail OR over the telephone, so there is absolutely no reason why they should be available otherwise. Since the idea a network of computers, the industry has wonderfully advanced some good blocking devices, but they are not an alternative fo ...

... but we can see now that we hope to revolutionize computer design and performance," said Robert R. Birge, a professor of chemistry, Carnegie- Mellon University, Pittsburgh. "Now it's 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. W ...

... to actually become human. By definition, tools are designed specifically for certain tasks, and as technological tools, the T800 and the replicant are deigned to meet specific specifications. In Terminator 2, the T800 is a multipurpose cyborg assigned to save John Connor, given a series of “mission parameters,” initially characterized by his computer logic. He often advises John based on permutations of the T1000's next move, similar to the way a chess computer decides what move to make next. Just as the T800 is designed to perform solely as a unemotional computer, the ‘replicants' in Blade Runner are designed to work in slavery without protest. Since ...

... alternative to other more expensive operating systems. Due to the very nature of Linux's functionality and availability, it has become quite popular worldwide and a vast number of software programmers have taken Linux's source code and adapted it to meet their individual needs. At this time, there are dozens of ongoing projects for Linux to different hardware configurations and purposes. Linux has an official mascot, the Linux Penguin, which was selected by Linus Torvalds to represent the image he associates with the operating system he created. Although many variations of the word Linux exist, it is most often pronounced with a short " i " and with 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 people. Although freight trains are still used all across the nation, rail intercity freight has accounted for a decreasing share of the total ton mileage over the past 30 years. This is mostly due to the increase in truck transport. Rail passenger traffic had also declined over the years until ...
