Difference between CS and IT

My family been telling me to pursue IT but they can't even explain me in details what kind of stuffs they do. I try googling but still have some confusion about it. I personally find CS interesting but I have never look into IT. Hope someone of you can explain their most significant differences and what kind of stuff they do on a jobs. They are saying it like it's a better path than CS but I want some clarification between this two before I take any of the course for college.
