Case Project #4

1. Since, you purchased a new PC that includes serial mouse, an internal modem, two hard drives and two SCSI controllers, you can apply the following IRQs: the IRQ3, IRQ4, IRQ10, IRQ11.

2. In this case, the result that the proposed solution produce is the (b.) the required result but only one of the optional desired results. The server can be able to handle all the networks traffic it receives with reasonable response time and make sure the server won't slow down the network.If collision of data ocurs, it is sensed by all nodes. If all nodes on the network have an IP address, the network portion of the IP is the same for all the nodes. To avoid the heavy loading of data, you can purchase additional hardware devices that can used to minimize the data loading.

3. For me, Bob should (b.) run a dedicated cable from the server to Bob's machine, and put him on his own network segment. This way, his laggard performance won't affect anyone else because if he replace the 8 bit NE1000 with a 32 bit NE3200 EISA card, he may encounter problems. The problem is: After being booted, the server lets workstations net use to it and the server can see other servers; though after a couple minutes,it completely loses contact with the network. At this point, we are unable tonet use to any other servers (-path not found-) an error message appear, and workstations lose all contact with the server.


4. In this problem, I choose to (b.) remove all non essential adapters and install the NIC. Then use whatever IRQs are available to install as many of the other adapters as you can get working. The most common method of checking the card is to see whether other devices can be found. Use Network Neighborhood and check for all devices on the network. Another method is to ping known devices by their IP address. By the time you install an NIC, many other sub system have already been installed in the computer such as mouse, floppy drive, hard drive, modem, CD-ROM, and so on. The I/O and interrupt you assigned to the NIC might be used by another device. Therefore, you have to find an unused IRQ for the card. In general, any unused IRQ works. However, check your NIC literature for special precautions.
