What mean by hyperlink and it's use for what?

I want to make presentation and want to bring excel file in power point, so how is can copy that, which can be format easily if i need to do correction in excel data.

You use the hyper link and add it to whatever you need like email!!!!!!!!!!!1

A hyperlink is the same as a link on a web page, it's just the full name for it. As for bringing in an excel file into a power point presentation, well open the Excel file, drag to select the section you want, hit copy, go to the Power Point, and hit paste. It should insert as a table. If this doesn't work, in the Excel spreadsheet, hold down alt and press prnt scrn (Print Screen), then open Paint, go to Edit>Paste, then select the Marquee tool, select the area you want, and then go to Power Point and paste it in as an image.

a hyper link is sued to add link to a keyword to a website URL.
