I remember the first day I use a computer. It was a strange box with a TV over it. The keyboard looks more like a typewriter than an actual keyboard. The mouse has only onebutton. The monitor has a black background and green letters. It works in text mode only. The GUI (Graphic User Interface) doesn’t exist then and you must use some commands to give orders to the PC. When you open the text processor, you only saw a clear menu bar over the black screen, and a rectangular cursor. You can see only plain text and havea few letters, no more than three or four, all them for dot matrix printers. In those days no one think may be possible see videos, chat with your friends or stay connected reading this page. What a long time has passed! Is an egregious difference!
