-Our normal replication is the deep copy, which will be copied completely again as a separate new individual exists. Therefore, changing the original copied object will not affect the new object that has been copied.-Shallow copy does not produce a separate object, he simply hits the original block with a new tag , so when one of the tags is changed, the data block changes and the other tag changes. This is different from what we have in the ordinary sense of replication.For simple object, it's
