Case Project 1-3 CNT Books has expanded considerably since you got the network up and run- ning three years ago. It now occupies an entire floor in the building, and its LAN has grown to include several servers and more than 60 workstations. CNT Books has recently purchased another book company and needs more space and computers. Expansion plans include leasing another floor four stor- ies above the current offices in the same building and adding 35 workstations and at least one more server immediately, with additional equipment purchases expected. What type of network is called for-LAN, WAN, MAN, or internet- work? What additional devices might be needed to ensure efficient network communication? Case Project 2-1 You have been hired to upgrade a network of 50 computers currently con- nected to 10 Mbps hubs. This long-overdue upgrade is necessary because of poor network response time caused by a lot of collisions occurring during long file transfers between clients and servers. How do you recommend upgrading this network? What interconnecting devices will you use, and what benefit will you get from using these devices? Write a short memo describing the upgrade and, if possible, include a drawing of the new network. Case Project 2-2 Two hundred workstations and four servers on a single LAN are connected by a number of switches. You're seeing an excessive number of broadcast packets throughout the LAN and want to decrease the effect this broadcast traffic has on your network. Wh at steps must you take to achieve this goal? Case Project 2-3 In Chapter 3, you learn about network topologies and technologies. As prepa- ration, do Internet research on the following topics: Physical versus logical topology Bus topology Star topology Ring topology Ethernet and CSMA/CD Show transcribed image text
