Power BI Desktop is a free, downloadable application that allows users to create reports and dashboards by importing, transforming, and visualizing data from various sources. It includes a visual interface for designing reports and a query editor for data transformation.
Power Query:

Power Query is a data connection and transformation tool embedded in Power BI Desktop. It allows users to connect to and import data from various sources, perform data cleaning and shaping, and create a unified dataset for analysis.
Data Modeling (Relationships and DAX):

Power BI enables users to create relationships between tables in their datasets and define calculated columns and measures using the Data Analysis Expressions (DAX) language. This helps in building a robust data model for analysis.
Visualizations:

Power BI provides a wide range of customizable visualizations, including charts, tables, maps, and more. Users can drag and drop fields onto the report canvas to create interactive and dynamic visuals that convey insights effectively.
Reports and Dashboards:

Reports are individual pages in Power BI Desktop that contain visualizations and insights. Dashboards are collections of multiple reports and visuals, providing a consolidated view of key metrics. Both reports and dashboards can be shared with others.
Power BI Service:

The Power BI service is an online platform where users can publish, share, and collaborate on Power BI reports and dashboards. It allows for centralized management of reports, data refresh scheduling, and sharing with a broader audience.
Power BI Mobile:

Integration with Other Microsoft Services:

Power BI seamlessly integrates with other Microsoft services, including Azure, Excel, and SQL Server. This integration enhances data analysis capabilities and provides a comprehensive business intelligence solution.
Natural Language Query (Q&A):

Power BI includes a natural language query feature known as Q&A, which allows users to ask questions about their data using everyday language and receive visualizations as answers.
Security and Governance:

Power BI offers robust security features, allowing organizations to control access to data and reports. Row-level security can be implemented to restrict data based on user roles, and encryption ensures data protection.
Power BI is used across various industries and business functions to transform raw data into actionable insights, facilitating informed decision-making at all levels of an organization.
