.... nautical miles above the Earth. They are continuously monitored by ground stations located worldwide. They transmit signals that can be detected by anyone with a GPS receiver. Using the receiver, you can determine your location with great precision. GPS is one of history's most exciting and revolutionary developments, and new uses for it are constantly being discovered. But before I go any farther it's important to understand a bit more about navigation. Since prehistoric times, people have been trying to figure out a reliable way to tell where they are, to help guide them to where they are going, and to get them back home again. Cavemen probably used stones an ....

.... site licenses. Many server programs are coming equipped with a program called "netlog." This is a program that monitors the computer use of the employees in a company on the network. The program monitors memory and file usage. A qualified system administrator should be able to tell by the amounts of memory being used and the file usage if something is going on that should not be. If a virus is found, system administrators can pinpoint the user who put the virus into the network and investigate whether or not there was any malice intended. One computer application that is becoming more widely used and, therefore, more widely abused, is the use of electronic mail or emai ....

.... actually kind of strange. It started in the 1800's when a man named Charles Babbage wanted to make a calculating machine. He created a machine that would calculate logarithms on a system of constant difference and record the results on a metal plate. The machine was aptly named the Difference Engine. Within ten years, the Analytical Engine was produced. This machine could perform several tasks. These tasks would be givin to the machine and could figure out values of almost any algebraic equation. Soon, a silk weaver wanted to make very intricate designs. The designs were stored on punch-cards which could be fed into the loom in order to produce the designs requested. ....

.... it is now apparent that this technology can be used for more practical purposes. These purposes include national defense, surgical procedures and various other applications. Society has not fully acknowledged the benefits of virtual reality as of yet because it is still under development. The reason for virtual reality remaining in its development for so long is mainly due to its complexity. The hardware that has developed so far is unable to make the large calculations required by a virtual reality based machine. However, as apparent in recent years, technology is advancing at an extreme rate. This is another reason why society's hopes for virtual reality should an ....

.... supported modulation method that will work over whatever quality line has been established for that call. There are two main differences in the types of modems for PC, internal and external modems. Evolution of Modems In the last 10 years, modem users have gone from data transfer rates of 300bps to 1,200 bps to 2,400 bps to 9,600 bps to 14.4Kbps to 28.8Kbps to, and to 33.6Kbps. Now new modem standards are emerging, reaching speeds of up to 56Kbps. Unlike the 33.6Kbps modems being sold today, 56Kbps is a significant improvement over 28.8Kbps modems. Viewing complex graphics or downloading sound files improves significantly with 56Kbps. The modem experts keep tellin ....
