C-Star Algebra - Is There a Simple Way of Explaining It?

C-Star Algebra is a type of subset of bounded linear operators. It's sort of like analysis or calculus being mixed with something like infinite dimensional algebra. And you get, so you get these linear operators, but operating on these things called Hilbert spaces. So they're just, and then people ask all kinds of questions about them. They want to know when two C star algebra are the same and when two C Star Algeras are different.
