intelligence, if any emotion, the

them
Ex: If the people need operating system
to control behavior, emotions, body, so
the computer must have an operating
system to manage hardware and

- Kinds of operating systems
There are two major kinds of operating systems
Command Line Interfaces(CLI)
CLIs use only text and no graphics to display
information and user navigates by mean of
the shell
Ex:MS - Dos,Linux
Graphical User Interfaces(GUI)
A program interface that takes advantage of
the computer’s graphics capabilities to
make the program easier to use
Ex:Windows,[X_Windowns],Macintosh OS
- History
Perhaps the most popular OS up
untill the 1990's was Unix on the
mainframe and [Ms-Dos] on the Pc
All versions of Linux and Mac OS X
can trace their roots to directly
back to the original Unix
Ms-Dos was microsoft
corporation's predecessor to
Windows
- MS-DOS and its information
MS-DOS was Microsoft corporation’s
prececessor to Windows
A program designed by Tim paterson of
Seattle Computer Products called QDOS
Bill Gates liked fuctionaly of it and
bought
He rebranded it MS-DOS (Rename) and
licensed it to IBM
MS-DOS became the underlying CLI for
all of Microsoft’s GUI OS upto and

- Windows and Unix. What is over availability?
The main OS today on PCs is of course
Microsoft Windows
Over 90% maket share
Windows stared out as a home and office
OS.It has become a serious challenger to
unix systems
Unix is a system of multi-tasking,multi-
user and stability for severs,workstations
and latops.
Unix also has a graphical interface (GUI)
such as microsoft windows

- The components of the operating system
The base unit of the operating
system is a collection of programs
called the kernel(the most basic
layer which control the hardware
and the file system)
Kernel basic facilities
Process management
Memory management
Device management
System calls
- The components of the operating system
Other programs which help the kernel
interface with the component and
peripherals are called device drivers.
Another main task for an operating system
is to control which users have access to
specific parts of a computer’s resources
Ex: Requre users to authenticate with a
username and password before being
permitted to use the system resources
OS will allow a system
administrator to set permissions on a file or
a directory www.themegallery.com
- Primary function of the operating system
Management of shared
resources

hardware

Ex: file management system
Provide a primitive system interface for
applications
Providing a basic system commands to
the machine operator (system command)
