D. Symmetrical Difference

Symmetrical Difference is opposite to intersect, it removes area that is overlapping. To do that open the tool from Vector > Geoprocessing Tools > Symmetrical Difference. You assign Input Vector layer and Difference layer and finally assign the output file name. Attributes from both the layer are copied.

E. Clip

Clipping allows you to clip the feature with the defined boundary line. To do that open the tool from Vector > Geoprocessing Tools > Clip. You assign Input Vector layer that you want to clip and Clip layer that’s boundary line will be used to clip and finally assign the output file name. It is similar to intersection tools, only difference is input layer attributes are copied.

F. Difference

Difference layers allows to create area of input layer that is not overlapped. To do that open the tool from Vector > Geoprocessing Tools > Difference. You assign Input Vector layer that you want to create that is not overlapped and Difference layer that is overlapping some area of input layer and finally assign the output file name. Attribute table holds the values of input layer.

G. Dissolve

Dissolve layer is similar to union but in this everything is merged by the common field and it works on single layer. To do that open the tool from Vector > Geoprocessing Tools > Dissolve. You assign Input Vector layer that you want to work on and dissolve field that is common and finally assign the output file name.



Clipping vector layer
The clip tool is an overlay function that cuts out an input layer to the extent of a defined feature boundary. The result of this tool is a new clipped output layer. If you can picture a cookie cutter, this is like using the clip tool. And carving out vectors and rasters is one of the most common operations in GIS. To clip data, you need points, lines, or polygons as input and a polygon as the clipping extent. The preserved data is the result of a clip.

1. 
   Select Layer from top bar and select add layer. Upload our shapefile and add to workspace
   

2. 
   Add new layer named Karakalpak and select toogle editing for this layer .
   

3. 
   Enter Vector menu , then select geoprecessing tools , then clip
   

After running, we can get the result we want
