Icons

Ever since the Macintosh was introduced in 1984, icons have been the way we view files on computers. An icon on your computer screen represents an object or a program on your hard drive. For example, the folders you see on your desktop or in open windows are icons. The files that you see in those folders are also icons. The trash can on the Macintosh and the recycle bin on Windows are both icons as well.
