According to Stanford University, "It is the science of getting computers to act without being explicitly programmed." 

It comprises analysis of past data to diagnose the reasons as to why certain events happened. Thus, it aims to answer - Why did it happen?

It is the AI programming that focuses on acquiring data and creating rules or algorithms that turn the data into actionable information.

It is about the electronic tagging and tracking of objects and people with bar codes, RFID devices, and other technologies and communicating the resulting data about locations, movements, and status.

It is a broad term that encompasses the processes, technologies, frameworks, and algorithms to extract meaningful insights from data.

It was designed and trained to carry out one particular task and cannot work without human interaction.

It uses multiple prediction models to predict various outcomes and the best course of action for each outcome.

It aims to answer - What can we do to make it happen?

This kind of AI does not just mimic or understand human behavior and intelligence, but also surpasses human cognition and ability.

It is defined as collections of datasets whose volume, velocity, or variety is so large that it is difficult to store, manage, process and analyze the data using traditional databases and data processing tools.
