    BIG DATA AND TARGETED MARKETING: A DIGITAL REVOLUTION

                      In the digital world, every online action, such as visiting a
                      website,  watching  a video,  liking  a post  or making  a
                      purchase, leaves a digital trace. When billions of these
                      traces are collected, they form Big data, which refers to
                      the massive volume of information from online and offline
                      sources  like social  media,  e-commerce,  GPS and
                      browsing history. Targeted marketing uses these insights
                      to deliver personalised advertisements and messages to
                      individuals  or specific  groups  based  on their  interests,
                      behaviour and demographics.

                             UNDERSTANDING MACHINE LEARNING ALGORITHMS

                      Machine  learning algorithms  are a core component  of the
                      digital  world and their  use  has significant  implications  for
                      digital citizenship. Understanding these algorithms is crucial for
                      navigating online spaces responsibly and ethically.

                      HOW MACHINE LEARNING RELATES TO DIGITAL CITIZENSHIP?
                      Machine learning algorithms are used to analyse vast amounts
                      of data  and make  predictions  or decisions  without  being
                      explicitly  programmed  for every  task.  They  power many  of
                      the services we use daily, including social media feeds, search
                      engines and targeted advertisements.
