one is named Netcentric Computing and the other is named Data Communication & Networking of course.

but on the serious side, a name of a course is merely a name, and that's it. what does this mean? it means that you cannot really tell what the course is really about by just looking at the name. And each university and colleges tends to name their courses in their own manner as well.

so how do you really go and tell what the difference is? by looking at the course outline from the exact university that you're looking at. take a look at the subject list, and the description of each of the subjects in each one of the courses to really find out. without knowing where each one of these courses are from, nobody else is likely able to assist you with any further details.
