Ahehe, was my question really unclear?  I don't know how to explain it but my professor said that there are business types that do not need networking, just computerization.  See I proposed a Computerized System for the schedule of Nurses and the Admission of Patients where the terminals for let's say the Pediatric, Front desk and others would be networked to a single database.  My proffesor told me that, that kind of system is for stand-alone and not networking.  That is why I am having a very hard time defining which business or system should have networking.

So I should ask for the business system not the business itself?
