You have been hired by a small company to install a backbone to connect four 100base-T Ether- net LANs (each using one 24-port hub) and to provide a connection to the Internet. Develop a simple backbone and determine the total cost (i.e., select the backbone technology and price it, select the cabling and price it, select the devices and price them, and so on). Prices are available at www.datacommwarehouse.com, but use any source that is convenient. For simplicity, assume that cat- egory 5, category 5e, category 6, and ?ber-optic cable have a ?xed cost per circuit to buy and install, regardless of distance, of $50, $60, $120, and $300, respectively.
