1. Data Science

The data science field of computer science uses algorithms to find meaning and insights from data. Data scientists are often responsible for managing and analyzing large data sets. This data can come from many different sources, such as customer surveys and data from sensors like heart rate monitors. Once the data is collected, data scientists use data analysis tools to extract insights and information. 

Data science projects are commonly used to help businesses manage their data more efficiently. These projects can help businesses categorize data, organize data sets, and even detect irregularities in the data that could pose a security threat. If you’re interested in data science, start by exploring tools used by data scientists and familiarizing yourself with the terminology and concepts. Once you grasp the basics, you can explore more advanced concepts and topics. Some of the computer science projects you can explore in this domain include: 

• Fake News Detection Using Python.
