Remember (Manager or worker?): The operating system starts the computer, shows the desktop, manages files and memory and runs other programs. Apps do one job each: word processor = typing, paint program = drawing, web browser = websites. Spreadsheet = number tables and marks; presentation program = slides for a talk.
