Explanation
1. Save:
- "Save" is used to save the current version of a file. It overwrites the existing file with the changes you've made. If the file has been previously saved, this action simply updates the file with your latest modifications.
2. Save As:
- "Save As" is used to save a file under a different name, in a different format, or to a different location. It allows you to create a new version of the file without overwriting the original. This is useful when you want to keep multiple copies or versions of a document.
