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. Some services--such as e-mail--may exist in multiple layers, for example. Cable and satellite television signals are brought to thetelevision sets via coax cable ("Coaxial Cable," 2 5). Modems were once required equipment for networks; today, their use islimited. Retrieved 2 May 2 5 from: <>.How to make a network cable. This research considers the terminology used innetworking, some of the common hardware types and their purposes, and how asmall network might be set up in a small business to greatest efficiency. Switches determine howinformation is filtered and flows within a network. (2 5). However, the goal of this processshould not be to place the hardware issues above the logical designstructure; instead, the physical design should seek to work within theparameters established by the logical design whenever possible. Specifically, "modem" came from combining "modulator" and"demodulator" and referred to the ability of the modem to convert theanalog signal used on telephone lines to the digital signal required bycomputers, and vice versa, with the analog "voice" data converted todigital data streams. Networking Technology Introduction Computer networks were once the exclusive domain of large companiesand large government organizations that linked computing resourcestogether. Cable modems work with advanced cable boxes to provide additionalfunctionality via the coax cable (Rainer et al, 2 4). Networkdesigners need to be aware, however, that the physical design process mayyield changes to the logical design, as well (Designing, 2 2). They may be shielded with a wiremesh; this is typical for network installations where it is critical thatdata transmissions move without outside interference. Retrieved 2 May 2 5 from: <>. The following illustrates a high-level logical design for a networkfollowed by a physical design (Designing, 2 2): [pic] [pic] Conclusion Understanding key terms is critical to setting up an effectivenetwork, and most small companies would be wise to hire an outsideconsultant to serve as their expert IT group in order to accomplish thistask. (2 3). Retrieved 2 May 2 5 from: <>.Hub. Fiber cable cannot be coiled tightly since it ismore sensitive to damage than copper cable, and it is generally used inenvironments that are relatively stable in terms of temperature and otherconditions. Cable modems allow for much faster transmission of data, and muchbroader bandwidth, because they are able to take advantage of the coaxcable capabilities and are not limited to the voice modem limits. Retrieved 2 May 2 5 from: <>.Coaxial cable. As already noted, twisted pair cables are composed of two insulatedwires twisted together and run as a unit. Gateways areoften the addresses of devices such as routers ("Gateway," 2 5). Cat5, or Category 5, cable refers to copper cablecomprised of four twisted pairs of copper wire terminated with an RJ-45connector. Thehigh-level topology addresses issues such as the layers that are containedin the network, such as content, application and services. Today, many home users use cable modems, which are connected to thecable signal sent over the coax cable connected to the cable televisionsystem. Retrieved 2 May 2 5 from: <>.McCabe, J. Computer Hope, Inc. (2 5). Since data cantravel at the speed of light, it moves more quickly than data passingthrough copper cable. T., Hershberg, C., Meier, A., & Nordman, B. Straightthrough cables-used for connecting a computer to a hub, router or switch,use 586A terminations at both ends of the cable. Routers, as their name implies, "route" datapackets within or between networks to ensure that they go to theappropriate destination. The cable was terminated according to a 586A or 586Bconfiguration. Services withinthe topology apply to the services found within each layer. When creating the logical design, the network designer typically takesthe following into account: high-level topology, services within thetopology, service flows, and networking components (Designing, 2 2). During this process, capacity issues are taken intoaccount as well as scalability issues and the needs of the organization inthe future with regard to both of these. Explanation of Terms Until recently, all network components were physically connectedthrough cables of one type or another. Cisco Systems. Retrieved 2 May 2 5 from: <>.Gateway. What's on the TV: trends in US set-top box energy use, design and regulation. Cross-over cables-usedfor connecting network components to one another, such as a router to arouter or a computer to a computer-use a 586A termination at one end and a586B termination at the other ("How to Make," 2 5). In recent years, wireless networks-including 8 2.11a, b and g have become commonplace. A USB hub, for example, can be used to connect many USB devicesto a computer that has only one or two USB ports. Network Analysis: Architecture and Design. Today, many small businesses rely on computer networks, and evenmany home users have networks set up so that several users can connect tothe Internet and to common peripherals-such as scanners and printers-through the network. In the 586Bconfiguration, the yellow and green wires are in opposite positions, withstripes being substituted for stripes, and solids for solids. Coax, short forcoaxial cable, offers greater bandwidth and transmission capacity thantraditional copper cable, and is used to transfer audio, video andcommunications. Fiber optic cable presents a much faster alternative to copper cablein that hollow cables are used to send pulses of light. San Francisco: Morgan Kaufmann Publishers.Rainer, L., Amann, J. ReferencesDesigning ISP architectures. Gateways are networkaddresses that are used as entry points to other networks. Computer Hope, Inc. Abridge does not analyze the data that passes through it; instead, it simplyforwards the information. Innovations in technology that occur between the twodesign phases may yield more powerful or economical solutions that were notknown during the logical design phase. Manufacturerseventually made cable-ready televisions, which eliminated the cable box fora while, but the box is back and more powerful than before. This is how data was originally sent over phonelines. The logical design identifies the topology,addressing, switching and routing protocols and even security issues thatwill be handled by the network ("Interview with," 2 3). Palo Alto, CA: Sun Microsystems. To do this, the router analyzes the data anddetermines the appropriate action. (2 4). When cable television first began to gain widespread acceptance in theearly 198 s, cable boxes referred to the ubiquitous box that sat on top ofthe television and was required to convert signals coming in on the coaxcable to signals that could be displayed on the television. Networks in small companies do not need to be complex, but mostbusiness professionals do not possess the requisite technical skills to setup a network without prior experience. Service flowsidentify the interaction between the various clients and servers.Networking components are defined by the network designer to provide theoptimum fit to the overall logical design, and include items such asrouters and switches. Computer Hope, Inc. Other computers mightalso be connected to the hub to provide direct connectivity ("Hub," 2 5) Bridges form the connection between two local area networks (LANs). Bridge routers serve as both routersand bridges, core routers work within a single network, and edge routersmove information from one network to another. During this phaseof network design, hardware issues or specific hardware is not yetselected, although it is likely that the network designer will have a goodidea of what is available to meet the logical design needs. (2 5). The other key component to networks, apart from cabling, is thehardware itself. In a wired network, cablescould take several different forms. While basiccable boxes continue to be "one-way"-that is, they provide data to thetelevision but do not feed data back to the source, advanced boxes allowfor interactive television, digital video recording (DVR), and video-on-demand. (2 3). This research examineswired rather than wireless networking options. The most fundamental building block is a hub, which issimply a device that allows multiple devices to be hooked to a singlecomputer. (2 5). Physical design follows logical design and consists of identifying theactual technologies and products that will fulfill the logical design(McCabe, 2 3). Copper and fiber optic are the mostcommon cable types. In a 586A configuration, Pins 1 and 2 are green stripe andgreen, respectively, Pins 3 and 6 are yellow stripe and yellow,respectively, Pins 4 and 5 are blue stripe and blue, respectively, and Pins7 and 8 are brown stripe and brown, respectively. Computer Hope, Inc. D. (2 2). The physical design may require modifications to the logical design ifno acceptable solution can be found that meets the requirements of thelogical design. Setting Up a Small Network Laying out a small network for the home or a small business includesboth the logical and the physical design, taking into account thecomponents defined above.
