.... the electronic mail. Second, there are discussion groups with a wide range of topics in which people can join. Finally, people are free to browse into vast collection of resources (or databases) of the World Wide Web. Electronic mail (e-mail) brings a unique perception into the way of communication. Although, it did not replace the traditional means of communication such as letters and telephone calls, it has created a new method of transmitting information in a more efficient way. E-mail saves time between the interval of sending and receiving a message. Sending an e-mail message halfway around the world can arrive at its destination within a minut .....

.... computer files (usually other executable programs) by inserting in those files' copies of itself. This is usually done in such a manner that the copies will be executed when the file is loaded into memory, allowing them to infect still other files, and so on. Viruses often have damaging side effects, sometimes intentionally, sometimes not. (Microsoft Encarta 1996) Most viruses are created out of curiosity. Viruses have always been viewed as a well written, creative product of software engineering. I admit there are many out there who create them out of malice, but far more people are just meeting a challenge in software design. The people who make anti-viru .....

.... the arrival of telecommunications this became possible very quickly all over the world. Telecommunications is one of the reason we live in such a fast-pace and high-tech society today. The first invention in the telecommunications field is the telegraph. It was invented by Samuel Morse and utilizes an electrical current to send signals in the shaped of dot and lines called the Morse Code. It was first used in 1844 and it was mainly reserved for companies which needed information quickly such as banks, this helped them grow and more efficient. With the telegraph one could pass a message across any distance almost effortlessly and it was cheap, so the need fo .....

.... to estimates by the U.S. Software Publisher's Association, as much as $7.5 billion of American software may be illegally copied and distributed annually worldwide. These copies work as well as the originals and sell for significantly less money. Piracy is relatively easy, and only the largest rings of distributors are usually caught. In addition, software pirates know that they are unlikely to serve hard jail time when prisons are overcrowded with people convicted of more serious crimes. The software industry loses more than $15.2 billion annually worldwide due to software piracy. Software piracy costs the industry: $482 ever .....

.... impact in most industries, providing a competitive advantage that has come to be essential to many businesses. Therefore, schools must also use technology to improve the educational process. School systems often consider purchasing a computer network, and justify its purchase by applying it to routine administrative tasks, such as attendance records and grading. While these tasks are very important, they only show a small part of what technology can do for a school. Technology must go further than simply keeping attendance; it must focus on keeping students interested and productive. Since computers and the Internet have expanded in such a way in which educ .....

.... works by triangulation, the process of finding where you are by the angle to fixed known points. In the old method of DME position determination, you would tune one DME channel and draw a circle on your chart around the DME transmitter, the radius of which was your DME reading in nautical miles. Then you'd tune in a second DME station and repeat the process. On your chart at this point there would be two circles whose lines intersected at two points. Even a vague guess of your whereabouts would be enough to discard the bogus point, and you'd be left with a pretty good idea of your position. Better yet, take a cut from a third DME transmitter and draw a thir .....

.... way of handling database management. (Mullins 1995) Traditional database design and data access were complicated. The database administrator's job was to oversee any and all database-oriented tasks. This included database design and implementation, installation, upgrade, SQL analysis and advice for application developers.. The DBA was also responsible for back-up and recovery, which required many complex utility programs that run in a specified order. This was a time-consuming energy draining task. (Fosdick 1995) Databases are currently in the process of integration. Standardizing data, once done predominately by large corporations, is now f .....

.... calls the Internet "the unlocked window in cyberspace through which thieves crawl" (Erickson 1). There seems to be an unlimited potential for theft of credit card numbers, bank statements and other financial and personal information transmitted over the Internet. It's hard to imagine that anyone in today's technologically oriented world could function without computers. Personal computers are linked to business computers and financial networks, and all are linked together via the Internet or other networks. More than a hundred million electronic messages travel through cyberspace every day, and every piece of information stored in a computer is vulnerabl .....
