Most networks today are based on Ethernet technology. Part of this is due to the ease of installation and reduced costs.

However, there are other network technologies still in use. What are they and where and how are they used most prevalently? How would you as the IT manager convince executive management that they should be upgraded?

More businesses are using just-in-time purchases to reduce warehousing costs and ensure an up-to-date inventory. How does the use of the extranet help with this process? What network issues must be reviewed to make it a success for both the business and the vendor?

Give an example from personal experience, research, or through something you read of an Intranet application that improved the way something was done in a company.  How did the application improve a particular process?  Can you see ways the application can be improved to improve the process even more?
