Oscillations are repetitive or periodic variations in time. They can occur between two or more states or around a central value.
Examples of oscillations include: A swinging pendulum, Alternating current, and Vibrations. 

An oscillator is a mechanical or electronic device that works on the principle of oscillation. There are two types of oscillators: linear and nonlinear. 

There are also different types of oscillatory motion, including:
Damped oscillations: These are a type of oscillatory motion where the amplitude of the motion decreases over time. This is due to friction or other damping forces.
Simple harmonic motion: This type of oscillatory motion occurs when the restoring force of an object is directly proportional to the length of its displacement from the equilibrium position.
Forced oscillations: These occur when an oscillating system is driven by a periodic force that occurs outside of the oscillating system.
Free oscillations: These occur when the body oscillates with its own frequency.
