Data science is an important field of computer science that has picked up steam as technology advances. It is also recognised as the future of AI (Artificial Intelligence).

Definition:

The aim of data science is to discover patterns in data. It's all about bringing to light the hidden insights that can assist businesses in making better business decisions.
So, all these hidden insights (or) these hidden patterns can be used to make better decisions in a business.
For Example: Netflix.

So, Netflix analyzes the user's movie viewing patterns to movie viewing patterns of users to determine what drives their interest and what they want to watch, and then gives them what they want.
So, data has a great deal of power; all we need to know is how to process it and extract useful information from it.

What is Lorem Ipsum?

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.
It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Why do we use it?

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy.
Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
