INTRODUCTION

4. HISTORY
Early in the 1960s, a new field that would
support the comprehension and interpretation
of the massive amounts of data that were being
gathered at the time was given the name "Data
Science." (At the time, there was no way of
predicting the truly massive amounts of data
over the next fifty years.)

5. WHAT IS DATA SCIENCE?
Data Science is a discipline that is constantly
developing, using computer science and statistical
methods to obtain insights and make useful
predictions in a variety of fields. In addition to being
used in fields like astronomy and health, data
science is also applied in business to aid in
decision-making.

6. NEED OF DATA SCIENCE
Data science allows businesses to effectively
comprehend enormous amounts of data from
numerous sources and gain insightful
information for more informed decisions. Data
science is extensively used in various
industries, including marketing, healthcare,
banking, finance, policy work, and others.
