Yes it does.
If you close a file in Excel and answer no when asked to save it, it means that the file will not be saved. If it is a new file, then it will all be lost. If it is an existing file, then any changes made since it was opened will not be saved, so the file will be as it was when it was last opened.
Book1.xls is the default name for a new document in Excel.
You can open a Notepad document direct in Excel. If it has been saved as a CSV file, then the data will come in separated into cells in Excel, where commas occur in the document. Each new line of data in the Notepad document will appear on a new row in Excel.
When you create a new document in the root of a library, the document is typically created directly within the library itself. It may be displayed in the root folder or as the most recent item in the document library's list view.
The most obvious visible difference is the ribbon bar (new menu system) displayed by all Office 2007 products. You also will notice a new file format.

See related links for what's new with Excel 2007. Also see the related links for how to match the old Excel 2003 menu items with the new Excel 2007 ribbon.
"Save" saves the document with the same name/type as you opened or created it. "Save As" allows you to save the document with a new name or format/type.
Normally when you open Excel there are 3 sheets open. They are Sheet1, Sheet2 and Sheet3. Sometimes you will want to give more meaningful names to those sheets. By right clicking on the sheet tab and clicking the Rename option or by double clicking, you can rename a sheet. So you could have many sheets with names on them that are meaningful to what you are doing, which is what we mean by naming sheets.
"Save" saves the document with the same name/type as you opened or created it. "Save As" allows you to save the document with a new name or format/type.
When you open new documents in Word, the program names them with a default name ("document x") determined by the number of new documents created during that session. The first one to open is "document 1," the second "document 2," etc.

That depends on the specific situation. If the document has been previously saved, you will have the file up to the point it was last saved, but without any of the new changes in it. If it is auto-saving you may have some more. If it is a brand new document that was never saved before, then you will have lost everything. If there was an error in Excel as you were working on it, you might get a recovered document, but if you just said you did not want to save it, as you've indicated in your question, then that won't happen. As a general rule, if you are working on a big document, save it every so often, even before it is finished, so that if you do something like you did by hitting "No" you will have at least got some work back. Make sure the Auto save is on, by going into the Tools menu and then Options and then in the Save tab, you can turn on autosaving. That will help recover a document if there is an error in Excel, so you won't have lost everything.
