Overview of Data Science
Have you ever thought of how Google Maps predicts the traffic around you? How does it show you the best route and the mode of transport? How does it show you the time you would require to reach your destination? It’s all with the help of data. When you enable the location feature on your mobile phone, you are sending your real-time location data to Google. Google uses this data, and all such data from other users, to know the number of vehicles on a specific route. Then, it uses this information to predict the traffic on that route. You can make this miracle once you decide on treading in the Data Science career path.
Consequently, we are living in a data-driven world with 4.4 billion users on the Internet. By 2020, it’s estimated that the data generated by every person on earth will be 1.7 MB per second (2.5 quintillion bytes per day).
For managing the enormous amount of data, we need the rockstars of data, called Data Scientists.
So, Data Science jobs are one of the hottest jobs of the 21st century. According to Indeed, the average salary of Data Science experts in India is ₹978,625 and, in the United States, it is US$135,000 per year. Also, Data Science jobs will be in high demand for the next 2 decades with a very bright future.
