What is AR, VR and Artificial Intelligence, Simply Explained.

AR(augmented reality)
AR is the technology of creating things in an image or video, which are looking real in image/video but they are virtually created through computer graphics, AR inserts object in real camera image but these are all live virtual illustration, now what Wikipedia says,

Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are "augmented" by computer-generated or extracted real-world sensory input such as sound, video, graphics or GPS data.

VR(virtual reality)
VR is a technology of making you feel that you are present in that environment that you are  seeing, it makes you feel that all virtual  things happening in video you are watching through VR headset, are all nearby you, it makes all sensations through sound and realistic images that user is present in that environment, now Wikipedia ,

Virtual reality (VR) is a computer technology that usesvirtual reality headsets, sometimes in combination with physical spaces or multi-projected environments, to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual or imaginary environment.

AI(artificial intelligence)
AI is the technology of machinery intelligence means making machines more compatible with humans through specific software and hardware, its main purpose is to make Robots or machines to talk with us, to feel us and to take command through our voice in any situation and exactly to decrease human effort,
ex -google home, amazon echo etc; which take our voice commands and perform specific operations like if you say to google home "what is Taj Mahal" then it reply you that thing you want to know, but ultimately AI can be used for many other machines to make humans easy to work with these, now Wikipedia

Artificial intelligence (AI, also machine intelligence, MI) is apparently intelligent behaviour by machines, rather than the natural intelligence (NI) of humans and other animals. In computer science AI research is defined as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of success at some goal.^[1]Colloquially, the term "artificial intelligence" is applied when a machine mimics "cognitive" functions that humans associate with other human minds, such as "learning" and "problem solving".
