Second, an in- can allow you to have only one Internet connection while giving Internet access to all computers on your network. This is very important if you only have one phone line. If you were to add an additional phone line for each computer you wanted to be connected to the Internet, well, let’s just say that this would be a costly alternative. By using your file server on your network, as a PROXY server, you can just use one phone line to connect to the Internet. All you have to do is install a small PROXY program that says, “I am the Int ...
... supported on one or more semicircular stone arches. One of the most famous bridges would be The Pont du Gard at Nimes, France. It has three tiers of arches rising 155 feet above the Gard River, spans a distance of 855 feet. It was built in the late 1st century BC or the early 1st century AD. The cantilever bridge is characterized by spans that are supported not at the ends but near the center of the grider or truss. A suspension bridge 1010 feet long was designed and constructed by the German-American engineer John Roebling over the Ohio River, at Wheeling, West Virginia, in 1846.

... slide through. There is a student at Chichester Senior High School that has a home computer hooked online with the Internet system.

In return when he hits college life he will not know how to write a term paper. This will cause him to drop out. I know other students do the same thing he does. Now students will come out of high school not well educated. The Internet system is set up in a way we can give and receive mail. This mail is called electronic mail usually known as e-mail. This mail will be sent to where ...
... with each other by converting their digital communications into an analog format to travel through the public phone network. However, there is a limit to the amount of information that a common analog telephone line can hold. Currently, it is about 28.8 kbit/s. [Hopkins] ISDN allows multiple digital channels to be operated simultaneously through the same regular phone jack in a home or office. The change comes about when the telephone company's switches are upgraded to handle digital calls. Therefore, the same wiring can be used, but a different signal is transmitted across the line. [Hopkins] Previously, it was necessary to have a phone line for each device you wished to use simulta ...

Personal computers are single-user machines, whereas larger computers generally have multiple users. Personal computers have many uses such as: Word p ...
... not only in the operation of the highway construction and repair equipment, but also in the manufacture and transportation of the required materials. An increase in the percentage of people telecommuting to work will decrease the need for expanded highways and associated road maintenance. The first two areas related to getting to work. Once a person arrives at a central office working location, he or she represents another energy consumer, often times magnified many times over what would be required at home. The office building has heating, cooling, and lighting needs, and the materials to build it and maintain it require energy in their production and transportation. Working from home ...

... using up allot of our electricity. There are times in the summer when brown outs happen because if our excessive use of the air conditioners. Freon gets released into our environment. Today people are being kept alive longer and longer. People that have no chance of recovery are being kept alive on ventilators. This causes a great expense to society and an emotional stress on the family. Even though older people may beg to let them die medicine refuses to let them. This is slowly changing with living wills. Even though we love to watch TV it has also caused problems. Some people say that violence has increased in America because there is too much violence on television. Family tim ...
... spread by attaching themselves to other programs (e.g., word processors or spreadsheets application files) or to the boot sector of a disk. When an infected file is activated - or executed - or when the computer is started from an infected disk, the virus itself is also executed. Often, it lurks in computer memory, waiting to infect the next program that is activated, or the next disk that is accessed. What makes viruses dangerous is their ability to perform an event. While some events are harmless (e.g. displaying a message on a certain date) and others annoying (e.g., slowing performance or altering the screen display), some viruses can be catastrophic by damaging files, destroyin ...
