What is the use of GRASS in QGIS?
You can either load GRASS datasets in QGIS and then run modules using GRASS Tools. Or if you are working with data such as shapefiles, geotiffs, or geopackages, you can use GRASS algorithms in the Processing Toolbox. The GRASS integration for QGIS can streamline workflows involving spatial computation and map making.
What is the difference between QGIS and Qgis grass?
Whereas GRASS GIS focuses more on data processing and analysis, QGIS focuses more on cartography and map making. They compliment each other well and you can even use the QGIS GRASS Toolbox to load in GRASS data directly, and run GRASS processing commands from the QGIS menus. http://www.qgis.org.

The name of the file should start with GRASS module name + a word describing the specific task.
