Any oscillation in which the amplitude of the oscillating quantity decreases with time is referred as damped oscillation. Also known as damped vibration, http://www.answers.com/topic/damped-harmonic-motion
The frequency of a damped oscillation is the rate at which it repeats its motion. It is determined by the damping factor and the natural frequency of the system.
The quality factor (Q factor) of a damped oscillation is a measure of how "good" or efficient the oscillation is in terms of energy loss. It represents the ratio of the energy stored in the oscillator to the energy dissipated per cycle. A higher Q factor indicates lower energy loss and a more efficient oscillation.
Damped oscillation refers to a type of repetitive motion in which the amplitude of the oscillations decreases over time due to an external force or frictional effects. This results in the oscillations gradually coming to a stop. Examples include a swinging pendulum gradually losing its height or a vibrating guitar string eventually settling down.
Damped (or free) oscillation occurs when an object is set to vibrate at its natural frequency while forced oscillation involves the application of a force to keep an object in constant or repetitive motion.
Forced vibration: If a system is subjected to an external force, the resulting vibration is known as forced vibration if the frequency of the external force coincides with one of the natural frequencies of the system, a conditions known as resonance occurs (large oscillation). Failures of such structures as building, bridges, turbines and airplane wings have been associated with the occurrence of resonance.Damped vibration: Ifanyenergy is lost or dissipated in friction or other resistance during oscillation, the vibration is damped vibration.

Yes. You can have damping, independently of whether there is resonance or not.
what do you mean by terms under damped, critical damped and over damped frequency of control system?
the car tire....damped oscillation How about a speaker? When you apply signal to it, the cone oscillates in and out.

When energy is lost from the oscillating system, the amplitude of oscillationdecreases. When that happens progressively, we say that the oscillation is"damped". "Damping" is a description of the decrease, not its cause.
Vibratory motion of ideal systems in the absence of any friction or resistance continues indefinitely under the action of a restoring force. Practically, in all systems, the force of friction slows down the motion, so the systems do not oscillate indefinitely. The friction reduces the mechanical energy of the system as time passes, and the motion is said to be DAMPED. This damping progressively reduces the AMPLITUDE of OSCILLATION.
Oscillations (vibrations) are damped when they are changed by some action. For example, touching an oscillating (vibrating) tuning fork with your finger is said to be damping it. The oscillation (number of Hertz) of an electrical oscillator, such as a TV tuner, is changed by varying the settings of the tuner.
