Whats the difference between an atom bomb and a hydrogen bomb?

The atomic bomb was a pure fission device, utilsing compression
of a sub-critical uranium (Little Boy) (or plutonium: the Fat Man
nuclear weapon) to cause an explosion.
The H-bomb is a 'hybrid' device utilising a 'primary' charge that is effectivly an atomic bomb but a 'secondary' charge is also used, a container of hydrogen (deuterium and/or tritium) which undergoes fusion due to the heat/pressure/neutrons released by the primary.
Atom: pure fission
H-bomb: fission/fusion hybrid
