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. Programs were submitted-sometimes via punch cards-and run with results often printed anddistributed to the users, sometimes days after the initial data processingrequest was made. 2 9): 14.Mitchell, B. Latency refersto the delays that occur during transmission. The Internet is giant network of computers that areconnected in a variety of ways, including through both wired and wirelessconnections, and the types of data that flow across the Internet isexpanding. The pressure to continue to increase the speedat which data moves from one computer to another on a network is strong ascompanies such as NetFlix seek to deliver full-length movies over theInternet. Special Ethernetcables are used to connect the machines; these cables typically have alimited run of 1 meters, but the use of bridge devices makes it possibleto link physically unconnected locations-such as multiple buildings at acompany's campus. This data is then transmitted to a ten terabyte server at thecredit union's main branch, and a six terabyte server at a remote branch.Such high-resolution images are an ideal application of gigabyte Ethernet("How Cascade," 2 9). Nonetheless, data rates use the thousand, million and billionreference for "bytes" for kilobyte, megabyte and gigabyte, respectively. The other constraint on data rates is that of latency. Thisnetwork can support data transfer rates of one billion bytes per second;since a byte typically contains 8 bits, this is a significant increase inthe order of magnitude of data that can be transferred. Bandwidth is the capacity of any transmissionmedium; that is, how much data can be pushed through at any point.Bandwidth can be thought of as the "pipeline" through which data travelswith the result that the greater the bandwidth, the more data that can movethrough the network. Soon, bits persecond were insufficient for measuring speed, and the baud rate gave way tokilobits per second (Kbps). A disk drive that is onemegabyte contains 22 bytes, while a disk drive that is one gigabyte is 23 bytes. Technology has proved able to providegreater bandwidth and lower latency to accommodate ever-higher transmissionrates, so it is not yet clear how much faster data can move. Early modems using acoustic couplers could transmit data at 3 baud. Ethernet technology makes gigabit data rates possible;gigabit Ethernet networks are now commonplace. Networking When computers were initially introduced, they were used primarily bygovernment and large companies that could afford the extensive investmentrequired both in the special expertise to program and run the systems andin the facilities to support them. At that time, the primary constraint toproductivity was the processing speed of the central processing unit andusers had little interaction with the machine. If bandwidth is the"pipeline," then latency are blockages within that pipeline. As the amount of information increased and as technologicalinnovations led to wider "bandwidths," the amount of information that couldbe "pushed" from one computer to another also increased. Modern modems support data rates up to 56Kbps,or 56, bits per second ("Kbps," 2 9). 2 9 .Williams, M. Gigabyte Ethernet is not yet commonly deployed, but it is gainingacceptance in those environments where large amounts of sensitive data arecritical. These canlast for only a few seconds, a few minutes, or for much longer periods oftime. Although still rare,continued advances in Ethernet technology makes it possible to achievegigabyte data rates (Mitchell, 2 9). Gigabyte Ethernet When considering gigabyte Ethernet, it is important to consider bothbandwidth and latency. Gigabyte Ethernet thus requireslow latency in its topology and execution in order to provide the fullbenefit of its potential speed (Groenfeldt, 2 8). Gigabyte Ethernet requires wide bandwidths(broadband) in order to approach its maximum data transfer rate (). As computing power increased, "dumb" terminals wereadded to the still-large computers so that users could have easier access,but it was not until the invention of "smart" terminals and later themicrocomputer made it highly desirable that computers be able to "talk" toone another (Williams, 2 8).

Used for reconnaissance and surveillance, theGlobal Hawk uses a gigabyte Ethernet data bus in its avionics toaccommodate the aircraft's data transfer ("Global Reborn," 2 6). Not surprisingly, gigabyte Ethernet also has military applications.It is deployed on the newest incarnation of the Northrop Grumman GlobalHawk unmanned aircraft. However, the amount of data continued to expand both for internalnetworks (LANs) and the Internet. Not surprisingly, then, the gigabyte network has evolved. 2 9 ."Global Reborn." Flight International (4 July 2 6): n.p.Groenfeldt, T. Initially, connections were measured in "baud", which were bits persecond. References"Kbps / kbps, Mbps, Gbps." About.com. Conclusion Gigabyte Ethernet has not yet gained the market acceptance thatearlier data transfer rates have achieved, but acceptance is certain tooccur as larger and larger amounts of data are transferred over theInternet. "Ethernet." Wireless Networking, 2 9. This research considers the rise of networkingtechnology with an emphasis on Ethernet technology and the role of gigabyteEthernet in the future. Gigabyte Ethernet Introduction Today, computers are connected to one another within the same buildingand around the world. Other applications also have the need to transfer large files,whether to include large images, metadata, or other information ("Kbps,"2 8). 26 Jan. "Latency Focus: Missing the Forest?" Securities Industry News (3 June 2 8): ITEM 8182 2."How Cascade Has Gone Hi-Def(ense) in Monitoring Security." Credit Union Journal 13 (19 Jan. Increasingly, companies and individuals are interested inobtaining larger and larger amounts of data-such as feature length films-from the Internet, but such demand requires the ability to transmit suchlarge files quickly. Modems gave way to networks thatsupported one million bits per second (Mbps) and gigabit data rates (onebillion bits per second). Just as it was difficult to imagine gigabyte Ethernet data ratesduring the days of 96 baud modems, so it is difficult to imagine theupper range of data transfer rates. For example, a credit union in Oregon uses 34 cameras, some withmicrophones, to shoot 15 frames per second at up to three megapixels perimage. High latency creates bottlenecks that can significantly impact theefficiency of data transfer, with the result that high bandwidth can besignificantly affected by high latency. 26 Jan. When describing storage space, akilobyte is equal to 1 24 bytes, or 21 bytes. 2 9. Ethernet Ethernet is the most common transmission medium used in the physicaland data link layers of the internet protocol (IP). Note that "byte"has a slightly different meaning when used to refer to data rates asopposed to it describes storage space.
