- Windows is an operating environment created
by Microsoft. It provides users of PC with GUI (Graphical User
Interface).
- GUI is an environment based on pictures,
buttons, and menu options on the screen rather than on typed commands such
as old DOS. For example, if the user has to open the Microsoft Word for
writing, then he/she just has to double click the icon on the desktop and
the program will start.
- In GUI environment, you have to click
pictures on the screen or making selection from menus. Whereas in case of
DOS environment, the command is to be typed.

with entities such as icons (pictures that represent data files,
programs or folders), dialog boxes (frames that display information
and/or ask you questions) and windows (frames in which programs and
data are displayed).
- Any software programs the user run on the
computer is carried out by the operating system.
