Computers are a great boon to society that has allowed people to compile and store huge quantities of data that would take rooms and rooms of filing cabinets three or four decades ago. These devices can hold an immense amount of information in very small spaces which fit on a desk, in a purse, or even in a pants pocket. These machines have given people the capability to look up complex information and talk with friends and acquaintances with a simple click of the button. At the heart of it, this access with the simple click of the button is what makes computers so convenient and appealing.
With as rapidly as these machines complete tasks, it is easy to forget how much happens in that single click of the button. Taking a word document to PDF in order to post it online without it being altered can be done with a single click of the button. In reality though, the computer is taking the word document, moving it into XML, transferring it to XSL-FO, putting it through the FO, and then transferring it to PDF. This process of taking it through XSL-FO allows the file to store all its necessary data internally so it is independently operational. It’s amazing how much happens during a single click of a button.
