Show a block diagram for a backbone-based network configuration that will allow efficient use of network resources. (Assume the top level of the diagram is the building. The second level represents departments. The lower levels are individual employees, or network drops.)Locate and read a good article that describes ATM. Compare ATM methodology with the other networking topologies that have been discussed in your text or in other IT courses. Why do you think ATM lost its attractiveness?Locate, download, and install a copy of traceroute or tracert software. Use the software to ping an IP address at least 2000 miles from your location. Do this several times and record the paths that your packets take. Assuming that you’re not unlucky enough to have all your packets use the same route, draw a diagram of the portion of the mesh network revealed by your results.
