Paper Abstract: This article discusses two emerging technologies - PCI Express and the Head-Tracking Pointer. PCI Express is a new device for I/O technology to avoid bottlenecks in servers caused by the old Peripheral Component Interconnect expansion bus system used in PCs and servers. The Head-tracking Pointer uses a webcam to track head movements and move an on-screen pointer for those who cannot use a traditional mouse. Paper Introduction: PCI uses a shared bus technology which allows communication among thedifferent devices on the bus the different PCI devices such as thenetwork card a sound card RAID card etc are all attached to the samebus through which they communicate with the CPU and there is anarbitration scheme in place for deciding which device gets access to thebus when Stokes The advantages of this arrangement are that it issimple cheap and easy to implement However the more devices attached the more noise on Text of the Paper: The entire text of the paper is shown below. However, the text is somewhat scrambled. We want to give you as much information as we possibly can about our papers and essays, but we cannot give them away for free. In the text below you will find that while disordered, many of the phrases are essentially intact. From this text you will be able to get a solid sense of the writing style, the concepts addressed, and the sources used in the research paper. card etc are all attached to that it issimple cheap and
