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.

Damp oscillation system means the external forces are playing their role as drag force , air resistance , gravity etc. These forces causes to stop the motion of oscillation.
Please put oscillation in a complete sentence.

oscillator needs positive feedback in order to produce the undamped oscillations .This is done with help of he amplifier circuit.The oscillations are produced by the tank circuit cosisting of inductor and capacitor.The output of this tank circuit is fedback to the transistor which amplifies it and give back to the tank circuit input.If the gain of the circuit consisting of tank circuit and amplifier is more than one and the feedback given to tank circuit is in phase then we get undamped scillations as the output.
