This is an interesting and important piece of information to know, as to how exactly data science, AI, and machine learning are related to each other:

• AI: This area is trying to mimic human intelligence artificially. Just as humans are able to see, observe the data around them, and take decisions, the same is being tried through machines. It is a very wide area. The technology is still evolving. And to achieve a small task that a human does very easily through AI, a humongous amount of data is required.
• Machine learning: Subset of AI. Narrow focus on specific problem areas. The technology has implementations for real-life use cases. It is the connecting bridge between AI and data science.

• Data science: It is a field of data study and extracting information from it. This can use machine learning to analyze data, big data, and so on:
