Operating System Software Directs all the activities and sets all the
rules for how the hardware and software will work together.
Examples: Windows 2010, Unix, Linux, MAC OS, etc.

Operating Systems
GUI stands for Graphical User Interface
Uses pictures (icons) to represent files, folders, disk drives, modems, printers, etc.
GUI’s were created to make using a computer easier, more interesting, non-threatening to inexperienced users.
