I'm graduating in August this year with an I.T. degree. How do I know what part of I.T. fits me best if I don't have any real-life exeperience?

I absolutely love technology. So, for the most part, I think I will enjoy any I.T. job, but how do I know what my specialty is? I always get confused when people ask me what part of I.T. I would like to go to, but there are so many categories (IT Audit, Consulting, Business Analyst…) and I haven’t had any experience within any particular field. How do I know what I would like without actually getting any experience?
