Answer 2

An external file is a new file, different from an existing file. You can link this file with the existing one, you can modify it and many other thinks.
Example:
You have a HTML file. You have created a new JavaScript file. By using <script src="filename.js"></script> at the HTML code, you have attached it to the HTML code.
Not the best explaination, but I hope you got it✌
