NETWORKING TECHNOLOGY

Until recently, all network components were physically connected through cables of one type or another. In recent years, wireless networksùincluding 802.11a, b and g have become commonplace. This research examines wired rather than wireless networking options. In a wired network, cables could take several different forms. Copper and fiber optic are the most common cable types. Cat5, or Category 5, cable refers to copper cable comprised of four twisted pairs of copper wire terminated with an RJ-45 connector. The cable was terminated according to a 586A or 586B configuration. In a 586A configuration, Pins 1 and 2 are green stripe and green, respectively, Pins 3 and 6 are yellow stripe and yellow, respectively, Pins 4 and 5 are blue stripe and blue, respectively, and Pins 7 and 8 are brown stripe and brown, respectively. In the 586B configuration,

sure that they go to the appropriate destination. To do this, the router analyzes the data and determines the appropriate action. Bridge routers serve as both routers and bridges, core routers work within a single network, and edge routers move information from one network to another. Switches determine how information is filtered and flows within a network. Gateways are network addresses that are used as entry points to other networks. Gateways are often the addresses of devices such as routers ("Gateway," 2005). Modems were once required equipment for networks; today, their use is limited. Specifically, "modem" came from combining "modulator" and "demodulator" and referred to the ability of the modem to convert the analog signal used on telephone lines to the digital signal required by computers, and vice versa, with the analog "voice" data converted to digital data streams. This is how data was originally sent over phone lines. Today, many home users use cable modems, which are connected to the cable signal sent over the coax cable connected to the cable television system. Cable modems allow for much faster transmission of data, and much broader bandwidth, because they are able to take advantage of the coax cable capa
