A ballistic missile is a missile that follows a sub-orbital, ballistic flightpath with the objective of delivering a warhead to a predetermined target. The missile is only guided during the powered phase of flight and its course is governed by the laws of orbital mechanics and ballistics.
A rocket is a vehicle, missile or aircraft which obtains thrust by the reaction to the ejection of fast moving fluid from within a rocket engine.
Rockets are used for fireworks, weaponry, launching artificial satellites, human spaceflight and exploring other planets. While they are inefficient for low speed use, they can reach extremely high speeds particularly when staging is employed.

A missile is anything that is thrown, like bullets, arrows, and ICBMs. Maybe you have heard statements like, "the mob was throwing rocks and I had to constantly dodge the missiles coming my way." The word missile is a general term for anything thrown fast, and does not just mean a rocket powered weapon. The term ballistic means basically means uncontrolled, like a bullet or rock that has been thrown is not under control after it leaves the gun or your hand. An ICBM is a rocket powered missile that can be thrown thousands of miles by rocket power. The rocket engine only burns for 5 minutes or so and then runs out of fuel. After that the missile follows a ballistic path, which is a path totally out of our control, only following the laws of momentum and gravity, like a rock or bullet. It has no wings or fins, and even if it did they could not control the flight path since the missile is in the vacuum of space most of the time.
A rocket is just a way of providing the push that throws the missile. It is any machine that quickly burns a fuel and directs the exhaust in one direction to provide a push in the opposite direction by way of the action-reaction principle of Newton's 3rd law.

For the most part, they are one and the same, since most ballistic missiles are rocket powered now a days.
ballistic
[adjective] relating to or characteristic of the motion of objects moving under their own momentum and the force of gravity; "ballistic missile"
A "missile" is any object hurled through the air, from an arrow, to a rock, to a bomb. The term "ballistic" refers to an ancient Roman weapon (ballista) that used to hurl projectiles. So something traveling "ballisticly" is something traveling on its own momentum, with no other type of propulsion except for the initial burst that got it moving in the first place. Technically, a "ballistic missile" is an arrow, a bullet, a catapulted rock, or a rocket that buns all of its fuel at once and then coasts to its target.
Most intercontinental missiles are rockets which are designed to have just enough fuel to get their payload into space, and then the warhead (usually a nuclear bomb) coasts on its own momentum to the target without anymore power from its engine.
====edit====
bal·lis·ta
[noun] an ancient military engine for throwing stones or other missiles.

There is no difference except their payload and size. A ballistic missile is just another kind of rocket. In fact rockets were used as ballistic missiles before they were ever used for space research. The first manned space flights were launched on ballistic missiles with spacecraft in place of warheads.

BALLASTIC MISSILES:Missiles which spend most of their trajectory in unpowered flight, and which don't use aerodynamics to alter their course, are known as ballistic missiles (because their motion is largely governed by the laws of ballistics). These are in contrast to cruise missiles, which spend most of their trajectory in powered flight.
ROCKETS:In all rockets, the exhaust is formed from propellants carried within the rocket prior to its release. Rocket thrust is due to the rocket engine, which propels the rocket by expelling the exhaust at high speed.

A ballistic missile follows a suborbital, ballistic path.
Rockets are often used to power ballistic missiles, especially inter-contintental ballistic missiles (ICBMs)

A ballistic missile is such,that when it's propulsion system shuts down it then coasts to it's destination.
A rocket is such that unless it goes into orbit or sub-orbit it's rocket must keep firing to take it to it's destination.
