.... able to tap into the world wide web where vast amounts of information is at the fingertips of the user is a marked improvement from 10 years ago. Furthermore, the use of computers in the home has extended the hours we can learn at a higher level without the environmental pressures of school or work thereby improving the way we learn.(paragraph)Also, the use of computers has expanded our choices for entertainment. As an example, the all-American game of Monopoly can be played by a single person and a computer and the need for several people has been obsoleted is one way our choices for entertainment have been expanded. Another example of our expand .....

.... started with one network. In the early 1960's the Cold War was escalating and the United States Government was faced with a problem. How could the country communicate after a nuclear war? The Pentagon's Advanced Research Projects Agency, ARPA, had a solution. They would create a non-centralized network that linked from city to city, and base to base. The network was designed to function when parts of it were destroyed. The network could not have a center because it would be a primary target for enemies. In 1969, ARPANET was created, named after its original Pentagon sponsor. There were four supercomputer stations, called nodes, on this high spe .....

.... and cantilever bridges, are known to have been used in ancient India, China, and Tibet. Pontoon bridges were used in the military expeditions of the Persian monarchs Darius I and Xerxes I. The Romans built many timber-trestle bridges. Surviving roman bridges, however usually have a level road 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 sup .....

.... 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 and twigs to mark a trail when they set out hunting for food. The earliest m .....

.... on where and who you are working for. Usually the average working environment is indoors, quiet, temperature controlled and usually alone. Working Schedule The working hours vary as well. Computer Technician's are on call 24 hours 7 days a week due to the fact that most companies computers are running all the time and cannot wait long for their computer to be fixed. Salary The average salary for a Computer Technician is approximately $65,500 per year. To become a Computer Technician you need one or two years of technical training and you must have good math skills Which most technical and vocational schools offer. There are no licensi .....

.... files to floppy diskettes, hand-carrying them to the other computers, and copying the files one-floppy-at-a-time to each, individual computer. This would be a very slow process, compared to a fast network speed. Additionally, if one computer on your network crashes, you can move to another computer and continue your work. So, if you use your network and file server effectively, you can have a high degree of reliability, security, and efficiency. 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 .....

.... came out, paving the way for new and faster computers. Intel was the most proficient in this area and came out with a range of processors from 66 MHz-166 Mhz. These processors are also now starting to become obsolete. Todays computers come equipped with 400-600 Mhz processors that can multi-task at an alarming rate. Intel has just started the release phase of it’s new Pentium III-800MHz processor. Glenn Henry is quoted to say “Megahertz is all people care about� and this is too true. Sys Technology recently came out with what they claim as the “fastest commercially available PC�. This computer runs at an astonishing 1000 Mhz or 1 .....

.... across the room. To be sure, this isn't your ordinary corporate environment. Smith doesn't have a permanent desk or workspace, nor his own telephone. When he enters the ad agency's building, he checks out a portable Macintosh computer and a cordless phone and heads off to whatever nook or cranny he chooses. It might be the company library, or a common area under a bright window. It could even be the dining room or Student Union, which houses punching bags, televisions and a pool table. Wherever he goes, a network forwards mail and phone pages to him and a computer routes calls, faxes and E-mail messages to his assigned extension. He simply log .....

.... 1 millimetre is 10 co-ordinate points. CADD systems were developed along with the computer. They were developed very slowly. They went from being very large, clumsy, elaborate machines which needed lots of human intervention to one program on a floppy disk. When the power of computers increased, so did the possibilities of CADD. Images on CADD systems are drawn with the aid of a keyboard, mouse, or tracking ball. One selects the starting point of a line, the ending point, and the line is drawn. A scale at the bottom of the screen tells how long the line will be. On some CADD systems, the computer itself can measure how long the line .....

.... first modem speed was 300 baud and from there a 600 baud than 1200 and so on. The fastest modem made today is a 56k which is very fast. Not as fast as ISDN (The Wave offered through Rogers cable) or even as advanced as Satellite modem. Most people now have 14.4 or 28.8 baud modems (Baud is "Slang" for Baud Rate Per Second) the reason for the increase in 14.4 and 28.8's is that they are cheap and fairly recent and haven't gone out of date yet. There are two types of modem external and external modems internal plugs into a 16 bit port inside your computer and external connects through either a serial (mouse)port or a parallel (printer)port most people .....
