Drones are rapidly growing in popularity. They are still in the infancy stage in terms of mass adoption and usage, but drones have already broken through rigid traditional barriers in industries which otherwise seemed impenetrable by similar technological innovations. Over the past few years, drones have become central to the functions of various businesses and governmental organizations and have managed to pierce through areas where certain industries were either stagnant or lagging. from quick deliveries at rush hours to scanning an unreachable military base, drones are proving to be extremely beneficial in places where man can not reach.

Whether drones are controlled by a remote or accessed via a smartphone app they possess the capability of reaching the most remote areas with little or no man power needed and require least amount of effort time and energy, which is one of the biggest reason drones are being adopted worldwide. Drones are widely used in military as target decoys, for combat missions, research and development and for supervision. drones have been part and parcel of military forces worldwide. Commercial usage of drones is gaining steady momentum. As it becomes cheaper to customize commercial drones, the door will be opened to allow new functionality in a wide array of niche spaces. Sophisticated drones could soon be doing everyday tasks like fertilizing crop fields on an automated basis, monitoring traffic incidents, surveying hard-to-reach places, or even delivering pizzas.
This paper gives an introduction to drones, what are they, how do they work - Technology, features and components, types of drones, there functional areas and challenges and potentials of drones.
