File extensions are typically three letter abbreviations that identify the type of a file located at the end of the file name.
The data files within Windows, for example, have application associated data (for example Music files should be playable by Media Player)- in other words if you have a music file and simply double clicking the music file doesn't launch the correct application; you would need to reinstall the music player application (say Windows Media Player.)

This is going to depend on the type of file that you are trying to open. The file extension is created depending on the software (and version) that was used.

You would need to have the correct software to open the file, but in many cases, Microsoft may make a viewer that you can download (depending on the file of course)

There is no answer for this, because it is the wrong question. A files extension doesn't matter to the file, it only exists so that the Operating System (OS) knows what application to open the file with.

What are the three or four characters right of the period in a file name where the file can be hidden or displayed?
That is the file extension. Each file has this extension to tell the system what to do with the file. For example, a program has .exe at the end. This means that it is an executable file, so the system will launch it as a standard executable. A document has .doc or .docx. The system checks file association when you run it, and tells whatever program is set to handle documents to open that file. If you have MS Word, then it will open the file. If you use Open Office, then that program will open it. If you change the extension, then a different program will try to open the file. For example, changing a .jpg to a .txt will open notepad. However, the file is not actually plain text, so you will see many pages of gibberish, since notepad doesn't really know what to do with the image file.
What is difference between File name and file extension?

For example, in document.docx, ".docx" is the file extension indicating that it is a Microsoft Word document.

Yes. If the file ends with .zip, it is a ZIP Archive file. There is a way to change the extension, however, using an extension changer found on the internet. The filename extension (characters to the right of the dot in the file name) identifies the type of file (unless this extension is renamed by a computer user) in most cases. The type of file will identify what can use or open the file, but not necessarily what created the file.
