1.Example for use of MS Word
In BBA, you would have Business Communication, if you have to write an essay on Barriers of Communication, then you would choose MS word. Once you type the answer in orderly fashion with heading and sub-headings, then you save a draft. On the saved draft you can use the tools of font type, size, numbering headings and items, then line spacing with justification to have a crisp clear flow of text. once you finish, you can use the spell check and grammar tool, finally see the text in print preview mode that will give you an idea of how the essay is going to look like.
2.Example for using MS Excel
If you have to write an assignment on finanical accounting a basic balance sheet of a company, then you will use the MS excel
a.revenue for sales
b.interest from deposits
a.dues to creditors
c.payments for purchase made.
Open an excel sheet, you have many rows and columns for you to add the item name and the figure against it
you keep adding worksheets for various items that fall under a common heading and save it.
In excel once the entires are made, the figures (money or percentage or actual numbers) can be arranged in asceding or descending order, to total sum can be calculated and even a graph can be created and added to the page.For the above example you can have
4 different worksheets, make the entires and create graphs for the same.

If you have to make a presentation to the class or the teacher/guide, then you use MS Powerpoint, where in each slide can have few key points listed, you can add an image or a graph by the side of it.
