What are the functions of scroll lock, print screen and pause buttons?
How I can use and where I can use this key?
Scroll lock allows the computer to stop scrolling to the right of the screen moving along, printing screen allows you to copy everything you see on your computer and then paste and edit a document. I found this definition of the pause button, a key that can be used to temporarily stop data visualization. Typically, you use the pause button to freeze the data that moves across the screen. To continue scrolling, you can pressing any key. DOS, an alternative to using the pause button is the use of addition, a page screen that displays the data at once. http://www.webopedia.com/TERM/P/Pause_key.html
