Case Project 3-1 Old-Tech Corporation has 10 computers in its main office area, whichis networked in a star topology using 10 Mbps Ethernet hubs, and wants to ROECTS add five computers in the manufacturing area. One problem with the exist ing network is data throughput. Large files are transferred across the net- work regularly, and the transfers take quite a while.

Adding the manufacturing computers will only make this problem worse and result in another problem. Because the ceiling is more than 30 feet high, there's no easy way to run cables to computers, and providing a secure pathway for cables is next to impossible. Devise a
