What is a massive collapsed star that has such enormous gravity?

You're talking about a so-called "black hole".
It doesn't necessarily have any more gravity than a normal star with
the same mass has. It's just that if the mass is all crammed into a tiny
space, then you can get much closer to it, and THAT's where the gravity
is stronger.

What is a massive collapsed star?
A massive collapsed star is a dead star.
A massive collapsed star that has such enormous gravity that nothing - not even light -can escape?
That's typically referred to as a "black hole", especially in the popular literature. You probably suspected that, or else it was an incredible coincidence, when you decided to deposit this question in the WikiAnswers category titled "Black Holes".
A star that has collapsed under gravity?
A black hole
The remains of a massive star pulled into a small volume by gravity?
The remains of a massive star pulled into a small volume by gravity?
Is a black hole a solid collapsed star or a empty gravity field?
It contains the entire collapsed star, however the star has collapsed to an infinitesimal point (or infinitesimally thin ring if its spinning) singularity, leaving everything around that totally empty except for warped spacetime (which is what causes gravity).
A collapsed star whose gravity is 100000 times stronger than earth's?
Neutron Star
What do a neutron star and black hole have in common?
Both are the collapsed remnants of massive stars.
What is a dense collapsed core with a very strong gravitional pull that forms when a very massive star become a supernova?
Neutron Star
What prevents a pulsar from gravitational contractions?
EVERY star - every object in the universe, actually - is in a balance between its internal pressure trying to cause it to expand, and the mutual attraction of its own gravity. Planets of every size, and stars of every size, they all exist in this balance. A pulsar got this way because the original star exploded and CRUSHED the core of the star into "collapsed matter", where all the protons, neutrons and electrons are merged together, without the massive space that normally separates these particles. Only the enormous gravity of the star could keep it collapsed that way, and it can't collapse any further because of nuclear pressure. If a lot more mass were added - for example, if two pulsars were to collide and merge - then the added gravity MIGHT cause them to continue to collapse - into a black hole. Some people ask "How much would a cubic centimeter of neutron star material weigh on Earth?", but the question is meaningless; you cannot take the collapsed matter away from the gravity source that keeps it collapsed, and if you could, it would re-expand into normal matter. Probably explosively.
What happens when the gravity of a massive star is ablle to overcome neutron degeneration?
When the gravity of a neutron star overcomes the degeneracy pressure of the neutrons, the neutron star collapses into a black hole.
What is the remains of a massive star pulled into a small volume by gravity?
A black hole
What difference of a star and a planet?
A star is a luminous ball of plasma held together by its own gravity and produce energy through thermonuclear fusion. A planet is a body orbiting a star massive enough to be rounded by its own gravity but not massive enough to conduct fusion.
