The Transition from Text-Based Computing to the Graphical OS. In the early . 1980’s. desktop computers began to be introduced with GUI Operating Systems. The Apple Lisa and Macintosh as well as Microsoft’s Windows OS replaced typed (text only) commands for file and software application management with more user-friendly graphical manipulations with a new type of controller, the mouse. Using the mouse a user could move a file into a directory by clicking and dragging a graphical image of a file into the graphical image of a folder. These graphical images are associated with the files and directories they represent by standard commands of the OS that have been hidden from the user (this is call abstraction)..
