Memory is used for the purpose of running programs, for example, your text editor. The text editor stores the file you are editing as what is known as a 'buffer' in your memory instead of modifying the file in-place. This is what makes undo/redo possible.

No, back button is not like undo. Back button takes you to the previous page you have opened. If there is no previous page or if you are at the first page, back button will not work because there is no page opened previously. Undo : It erases your current do, or current task. If you are playing cards in computer, press undo, your last move of card will be cancelled.
