When you do a save, the changes are applied to the document you originally opened. When you do a 'save as', you have to choose a name and a location where a copy of the document will be saved; this copy will have changes you are currently making to the document. You can then exit the document without saving, and your original document is unchanged. The copy that you 'save as' is still intact, with changes. You can also do a 'save as' without making any changes, just to have another copy of the document existing with a new name and/or location.
It allows you to save as a different file name, effectively creating an entirely new file instead of saving over the old one. The old one is kept.
