.... to find the briefcase, an ordinary computer has to make it way through long strings of 1’s and 0’s until it arrives at the answer. But what if instead of having to search by yourself, you could instantly create as many copies of yourself as there were rooms in the building all the copies could simultaneously peek in all the offices, and the one that finds the briefcase becomes the real you, the rest just disappear. – (David Freeman, discover ) David Deutsch, a physicist at Oxford University, argued that it may be possible to build an extremely powerful computer based on this peculiar r .....

.... 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 speed network. ARPANET grew during the 1970's as more and more supercomputer stations were added. The users of ARPANET had changed the high speed network .....

.... foreign countries. Government communicate using global technology. Mass meetings are held using video conferencing and speaker phones. Massive oversea trade deals are made overseas with the aids of phones, fax, and the Internet. Without these forms of communication we would have to take a plane across the ocean just to talk to someone on the other side of the pond. Types Of Communication Systems 1. A data communication system involves the use of computers in processing information. These systems are a part of any technical communication process. Data communication systems have evolved .....

.... how to receive, analyze and store information. These abilities are based on those of a human, the computer only generates information, without the authority to change the process in which it functions. The computer is only following instructions that “make it possible for a sequence of operations to be repeated over and over again until some condition is fulfilled, but in doing so to obey, not to fresh instructions on each repetition, but the same ones over and over again”(p.438). He then asserts that digital computers can be built and have been built that “in fact mimic the action .....

.... a chance on the job market. Because without education in this field there is no way to succed in life or to find ajob which would provide decant pay for an average person. However,other people have different opinion about this issue. In theit opinion knowledge of computers is not required in today's job market. They also thinks that people should not depend so much on computers but more on their own education and capibilities to make the right decisions. Even knowing for a fact that the computers are almost everywhere in use it's not appropriate for people to get addicted to them and to ma .....

.... the use of paper and pencil spread, particularly in Europe, the abacus lost its importance. It took nearly 12 centuries, however, for the next significant advance in computing devices to emerge. In 1642, Blaise Pascal, the 18-year-old son of a French tax collector invented what he called a numerical wheel calculator to help his father with his duties. This brass rectangular box, also called a Pascaline, used eight movable dials to add sums up to eight figures long. Pascal's device used a base of ten to accomplish this. For example, as one dial moved ten notches, or one complete revolutio .....

.... the beam after the first measurement, or if the car moves, the beam will automatically re-calibrate from its new position, still producing the same measurement results. Before repairs, Shark provides you with the ability to prove existing damage. This information is good to the vehicle owner and insurance company because it not only explains the cost of repair, but eliminates unnecessary work and surprises. During the straightening procedure, Shark will monitor selected underbody and upperbody reference points. Shark then calculates deviations from the manufactures specification .....

.... sites. "The two networks remained connected, however, thanks to a technical scheme called IP (Internet Protocol), which enabled traffic to be routed from one net to another as needed. All the networks connected by IP in the Internet speak IP, so they can all exchange messages." (Levine 12) Even though there were only two networks at that time, IP was made to allow thousands of networks. The IP is designed so that every computer on an IP network is compatible. That means any machine can communicate with any other machine. The Internet, also called the Net, is the world's large .....

.... own unrreliability. All the nodes from computers in the network would be equal in status to all other nodes , each node with its own authority to originate , pass , and recieve messages. The messages would be divided into packets, each packet seperatly addressed. Each packet would begin at some specified source node , and end at some other specified destination node . Each packet would wind its way through the network on an individual basis.In fall 1969, the first such node was insalled in UCLA. By December 1969, there were 4 nodes on the infant network, which was named arpanet, after its Pe .....
