Commutators In quantum...!!!!!!

Recently my class was taught about commutators and their applications in angular momentum operator.Unfortunately due to health reasons I was not able to attend them and now can't get any extra classes and to make things worse the books I was consulting don't have this topic altogether.
I would really like to ask as to what is a commutator and what is it doing in quantum mechanics.
I have previous knowledge of operators of momentum(p) and energy(E).
Also I have no idea whatsoever about the hamiltonian operator...
PLease i really need help in this one as it's quite an important topic I have been told...
Thank You..
Also It would be greatly helpful if you could tell me as to where can I find study material related to it online...
