Three Types of Software
 Operating System
Software
 Device driver
software
 Application
Software
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.
Device Driver Software
 Allows peripherals to communicate
with the OS (operating system).
