What is the difference between Computer science and information technology?

Hi I'm interested in computer courses to study, today I spoke to someone from one of the unis I was interested in one of the courses were more about designing and the other practical and more technical fixing and support the system. I'm really interested in that. Its called computer enterprising. .

But I want to apply to more but I get confused as every university calls the computer courses a different name. So i'm unsure if its software , or computer science , IT , IS with business. I think it could be IS with business what I'm interested in but I'm unsure. In some of the modules in the enterprise one has : information systems,computer programming ,data management , software testing , human computer interaction. developing internet applications supporting the systems kinda thing.
