.... without the costs of other forms of communicating such as telephone calls or postage for letters. The savings to be gained from e-mail were enough of an inducement for many businesses to invest heavily in equipment and network connections in the early 1990s. The employees of a large corporation may send hundreds of thousands of pieces of E-mail over the Internet every month, thereby cutting back on postal and telephone costs. It is not uncommon to find internet providers from twenty to thirty dollars a month for unlimited access to internet features. Many online serv .....

.... 100 million people (Cooke 61). Since the World Wide Web (WWW or W3) became popular through point-and-click programs that made it easier for non-technical people to use the Internet, over 21,000 businesses and corporations have become accessible through the Internet (Baig 81). These companies range from corporate giants like IBM, AT&T, Ford and J.C. Penny, to small law firms. "With the Internet, the whole globe is one marketplace and the Internet's information-rich WWW pages can help companies reach new customers," says Bill Washburn, former executive director of Commercial .....

.... not want to bombard you with numerous technological terms, but a brief explanation is necessary in order to understand arguments surrounding the issue. MP3 is a new way to save, copy, and play audio files on a computer. The audio files are near CD-quality and take up very little space on a computer’s hard drive. Previously, high-quality audio files were saved on a computer in WAV format, which takes up much more hard drive space than MP3. For example, a three-minute WAV file would use about 30 megabytes of disk space. But in MP3 format, the same song would use only two meg .....

.... of physical barriers. Passwords and firewalls are the two most common ways to secure a computer system. Passwords are the most common forms of computer and network security. They are the most common because of three main reasons. First of all, passwords are cheap to implement. Virtually all computers have a password system built into it already. Every home computer can have a password to lock out certain programs from users other than yourself. Even networked computers and systems can have an elaborate password system at a minimal cost to the company. Passwords are als .....

.... is digitally modulated to create a bit stream. This bit stream incorporates forward error correction, interleaving and other techniques to mitigate the effects of interference and weak signals that can produce high-bit-error rates. Link layer Usually a specialized radio protocol that employs a form of medium access optimized for the radio environment. Most link protocols involve interactions between the wireless modem and a base station, and mobile units do not communicate directly with each other. Network layer Some wireless WANs, such as RAM Mobile Data and ARDIS, use .....

.... the U.S. should renew its efforts to develop more nuclear plants. The United States should put the money which they would have used in order to renew their power plants, and use it to research others ways of receiving power. For example, if the U.S. developed solar power more and made it less costly, as well are more convenient for the average person, then there would be no more problems. In the past century many advances have been made in terms of energy. Power plants became the main source of energy, and towards the end of the century, new advances have been made such as sol .....

.... 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 improved upon .....

.... team of Chinese-American physicists declared that they had found a material that reached superconductivity at 92 degrees Kelvin. This was a big improvement. 92 degrees Kelvin is not a very high temperature, in fact, it is the equivalent of –181 degrees Celsius. Locating superconducting material above 77 degree Kelvin is a good thing because it means that the material will be easily produced and used. A theoretical understanding of superconductivity was advanced in 1957 by American physicists John Bardeen, Leon Cooper, and John Schrieffer. Their Theories of Superconductivity b .....
