A Document

Introduction
When you open an application, such as a text editor, it displays an empty area with a blinking caret:
In the same way, if you open a graphics application or a spreadsheet, it also displays an empty area, waiting for your work. You can then start performing the type of assignment that the application is expecting. For a graphics application, you can start drawing or loading pictures. For a spreadsheet, you can start entering numbers and performing calculations.
When you start entering text in a text editor or a word processor, you are said to create, or work on, a document. If you start drawing shapes or manipulating pictures in a graphics application, you are said to work on a document. If you start entering numbers and performing calculations in a spreadsheet, you are said to work on a document.

Saving a Document
After creating a document, you may want to preserve it for later use. Preserving a document is referred to as saving it. You have many options and this may depend on the application you are using. In most cases, if an application was created using the standards described and recommended by Microsoft, to save the document, on the main menu, you can click File -> Save:
* If the document was never saved before, a dialog box would come to assist you
* If the document was saved previously, it would be saved behind the scenes and the new version would include the new chchanges
A document can also be saved when you attempt to close an application:
If you create a document or modify one, if you close the application (or the window), you will be asked whether you want to save it. If you want to save it, you should click Yes. If the document was not saved previously, a dialog box would come up.
* If you have modified a previously saved document and if you attempt to close the application (or the window), the computer would ask you whether you want to save the document. If you want to save it, you should click Yes. In this case, the new version of the document would keep the changes you made. If you click No, the document would revert back to what it was before it was opened or the previous time it was saved
When saving a document for the same time, you must give it a name and a location.
