Company is planning a new network. Engineers in the design shop must have connections to accountants and salespeople in the front office, but all routes between the two areas must traverse the shop floor, where welders and metal-stamping equipment create potent amounts of EMI (Electro Magnetic Interference) and RFI (Radio Frequency Interference).
Given that both the engineering and the front office areas use 10BaseT (twisted-pair Ethernet), how might you interconnect the two areas? Assuring that the network has immunity from interference, reevaluate your choice citing the best medium(s) to use.
After the previous section of the network is complete, a CEO realizes that if the loading dock connects to the network, the dock workers could log incoming and outgoing shipments and keep the inventory more current. Even though the loading dock is nowhere near the shop floor, the dock is 1100 feet from the front office. What kinds of cable will work to make this connection? Choose the best medium for this project.
Using Ethernet Network Interface Cards or NICs, diagram simplest connection between two computers which will allow for communications and resource sharing.
