(i have a long way to go) on the CD that came with it has these 10 (in chap 5) case problems (these two are giving me trouble) i was wonding if you could give me a little input. i read through the chapter it talks about diffrent topoligies, and the diffrent backbones a network can have. serial, distributed, collapsed, or parallel. this chapter also goes over the IEEE standers

_____________________ your help will really be nice.

1. you have been asked to design a LAN for a very successful CPA firm with five departments in one building and a total of 560 employees, currently, the firm has no networked computers, and it is open to any suggestions you can offer. the firm does have a few requirements, however. it wants to make sure that it can easily expand its LAN in the future without exorbitant costs and without moving a lot of equipment. the firm also wants to make sure that every departmetn has very fast access to the LAN, and , of course, it wants the LAN to remain up at all times. it has already been decided to use the Net Ware 6.5 network OS. what kind of LAN would you design for this company?

2. Astro Tech Components, a company that manufactures parts for the aeronautics industry, is haveing trouble with a network segment in one of its departments. its IT director has asked you for help. the network consists of three hundred workstations using a mix of clients OSs and connecting to both UNIX and Windows server 2003 servers via Ethernet 10BaseT. the department experiencing problems is the CAD/CAM group, which had fought for months to get newer, more powerful workstations. now that the technicians finally installed the more powerful workstations, however, the users can't access the network. you ask what kind of network they are on, and the IT director says the this group was upgraded to 100BaseT, along with two other groups, just yesterday, because these users needed the extra speed. when you ask wheather all users are affected, she says that everyone-- even the departments vice president, who has full rights to the network--is prevented from logging on. you suspect that the CAD/Cam users' network access is the problem. what steps do you take next...
