                 Applications of Data Science

                 Data Science is used in various fields for different purposes. Let us discuss some of its applications in detail.

                 Internet Search

                 One of the most common applications of Data Science is in Internet search engines, such as Google. When you
                 type a question or keyword into the search bar, the search engine employs Data Science algorithms to deliver
                 the most relevant and useful results within seconds. These algorithms analyse vast amounts of data, including
                 website content, past search trends, and user behaviour, to determine which web pages should be displayed
                 first. For example, Google processes an enormous amount of data—more than 20 petabytes (which is 20 million
                 gigabytes) of data every day. Without Data Science, Google wouldn’t be as effective at delivering these results.






























                 Targeted Advertising

                 Another major application of Data Science is targeted advertising, which is widely used in digital marketing. You
                 might have noticed that the ads you see online often feel very personal, like they’re exactly what you were looking
                 for. This is because digital ads are powered by Data Science algorithms that help companies show you ads that are
                 most relevant to you.

                 Targeted advertising is not just limited to online ads. It can also apply to digital billboards at places like airports,
                 where the ads shown might be influenced by the time of day or the type of people passing by, based on their past
                 behaviour and real-time location tracking.

                                                                                      Statisical Data (Practical)  253
