.... were in performing various calculations. Computer science overlapped considerably during this time with the branch of mathematics known as numerical analysis, which examines the accuracy and precision of calculations. As the use of computers expanded between the 1950s and the 1970s, the focus of computer science broadened to include simplifying the use of computers through programming languages—artificial languages used to program computers, and operating systems—computer programs that provide a useful interface between a computer and a user. During this time, computer scientists were also experimenting with new applicat .....

.... shopping, telephone services, telebanking, teleconferencing, even the complex simulations of virtual reality. This souped-up television will itself be a powerful computer. This, many believe, will be the world's biggest media group, letting consumers tune into anything, anywhere, anytime. The most extraordinary thing about the multimedia boom, is that so many moguls are spending such vast sums to develop digital technologies, for the delivering of programs and services which are still largely hypothetical. So what is behind such grand prophecies? Primarily, two technological advances known as digitization (including digital compression .....

.... is at a computer equipped with these seven layers of function. So, in a given message between users, there will be a flow of data through each layer at one end down through the layers in that computer and, at the other end, when the message arrives, another flow of data up through the layers in the receiving computer. The actual programming and hardware that makes these seven layers of function is usually a combination of the computer OS, applications, TCP/IP and the software and hardware that enable you to put a signal on one of the lines attached to your computer. OSI divides communication into seven layers. The layers are in two groups. T .....

.... our society with messages of hate. The technological advances made as the Internet grew in popularity also allowed these groups to provide a new and unique look into the heart of bigotry in our society, and one which appeals to the instant gratification type of lifestyle in which we live. The accessability of these hate sights is also of great concern to those hoping to keep the Internet a safe place for people of all ages to surf without the negative influences of such sites. There is however another side to the groups on the net, groups that attempt to provide both education and a positive influence on the surfers, groups which go fr .....

.... story people would no longer read books to learn and improve their knowledge. People would rely on the computers rather than "try to memorize enough to match someone else who knows" (Nine Tomorrows, Profession 55). People would not chose to study, they would only want to be educated by computer tapes. Putting in knowledge would take less time than reading books and memorizing something that would take almost no time using a computer in the futuristic world that Asimov describes. Humans might began to rely on computers and allow them to control themselves by letting computers educate people. Computers would start teaching humans what co .....

.... Positioning Service or SPS is a positioning and time service which is available to all GPS users on a continuous, worldwide basis with no direct charge." (Tycho) The SPS is provided on the L1 frequency, which then will code a navigational message. The SPS accuracy is 100-meter horizontal, 156-meter vertical, and 340 nanoseconds time, and in total the SPS is ninety-five percent accurate. (Utexas) The Department of Defense also degrades this service so those consumers can use this service. Secondly, the Precise Positioning Service or PPS " is a highly accurate military positioning, velocity and timing service which is available on .....

.... the form of stories and experiences that they never dreamed of before. Perhaps the most surprising aspect of all this, however, is that the entire digital effects and animation industry is still in its infancy. The future looks bright. How It Was In the beginning, computer graphics were as cumbersome and as hard to control as dinosaurs must have been in their own time. Like dinosaurs, the hardware systems, or muscles, of early computer graphics were huge and ungainly. The machines often filled entire buildings. Also like dinosaurs, the software programs or brains of computer graphics were hopelessly underdeveloped. Fortunately for th .....

.... and play compatible boards, the computer detects and configures the new board automatically. The operating system may recognize some hardware components on older PCs. Mac userw will claim that they always had the convenicnce of a plug and play system, ubt the difference shows in teh flexibility of the two systems. Another set of arguments Mac users use in favor of their sysstems over PCs is in multimedia and networking capabilities. Mac users gloat that the Mac has networking technology built in the system. Even if a user did not use it, the network is included with the system. They cited that for the PC users and Pc users hate the .....

.... across the globe. a. The WARSIM 2000 simulation system will use a computer-based simulation and associated hardware to support the training of unit commanders and their battle staffs from battalion through theater-level as well as to support training events in educational institutions. Designed and built using modern computer technology, modern software engineering techniques, and validated algorithms and databases, it will allow units world-wide to train using their organizational equipment. A key feature of the system will be its use of technology to minimize the total Army's overhead associated with supporting training. The system wil .....

.... the limited back their freedom to be an active part of the human race. According to the Americans with Disabilities Acts, any office that has a staff of more than fifteen people now has to provide adaptive hardware and software on their computers, so that workers with disabilities can accomplish many tasks independently. Before this Act was passed the disabled were normally passed over for jobs because of their handicap, now however employers can be assured that people with disabilities can work in the work place just like people without disabilities. The self esteem disabled individuals have gained from the experience to work and be .....
