                        1.  Have you ever noticed how YouTube or Netflix recommends videos or shows you might like?

                        2.   When you check the Weather application or Google Maps, how do you think it knows the latest
                            temperature or the fastest route?

                      We live in a world where everything is connected by data. Every time we watch a video, search for
                      information online or even walk with a fitness tracker, data is being collected and used to make
                      our experience smarter and faster.

                      From school reports to shopping apps, from Google Maps to hospitals—Data Science is everywhere.
                      Let’s explore how it all works.

                             WHAT IS DATA SCIENCE?

                      Data Science is a field that involves extracting meaningful
                      insights  and information from a large amount  of raw
                      data. It uses tools, techniques and algorithms to analyse
                      and interpret data to help in decision-making, predictions
                      and solving complex problems.

                      Data  Science  helps  us  to  find  patterns,  trends  and
                      relationships in data.

                             WHAT IS DATA?

                      Data refers to raw facts or figures collected for analysis.
                      It can be in the form of numbers, images, text or sound.
                      To convert raw data into useful information, it needs to
                      be processed.
                      Data processing  includes  cleaning, organising  and
                      analysing data  so that  it  can be interpreted into
                      meaningful  information  and used  to  make  decisions
                      or solve problems.

                       In 2019, the total amount of data in the world was estimated to be 40 zettabytes.
