What’s in a Title?

I have seen so many IT titles lately, that it’s difficult to distiguish who’s who’s boss. What’s the difference between a Network Administrator and a Systems Administrator? Besides adding Senior in front of the title, what would be the next level to move up? Would it be IT Systems Manager? What would be an appropriate title to give an individual that is a Network Administrator, In house Tech, Programmer, Telecommunications consultatnt, logistics consultant, and even interior decorator at times? Does any have a list of how the IT Title Ladder goes from CIO/CTO down to entry level tech?

Thank You
