Scroll bar - this convenient tool allows users to move data up and down the computer screen. But when they're typed into a programming language and compiled to create a an executable file (a file ending with the .exe extension), they turn into a software application. As we mentioned earlier, you can use a programming language to control your computer. By using simple commands, you can program your computer to perform mathematical tasks, fill out web forms, compose an email message and send it off, or any number of other things.
