 DEFINITION OF OPERATING SYSTEM
 TYPES OF OPERTING SYSTSM
 FUNCTION OF OPERSTING SYSTEM
S.G.ISAVE4
OPERATING SYSTEM
 Operating system is a part of system software
 Operating system is a program which monitors,
controls and maintains the computer.
 Operating system is the set of programs that controls
the overall functions of computer.
 It provide a pleasant and effective interface between
the user and the hardware
 Makes the computer more convenient to use
TYPES OF OPERATING
SYSTEM
 UNIX
 LINUX
 SOLARIS
 WINDOWS
UNIX
 UNIX (Operating trademarked as unix ,
sometimes also written as unix in small caps) is a
multitasking, multi-user computer operating
system originally developed in 1969 by a group of
AT&T employees at bell labs
 It was first developed bn assembly language but
by 1973 had been almost entirely recoded in c ,
greatly facilitating its further development and
porting to other hardware.
LINUX
 IT IS AN OPEN SOURCE OPERATING
SYSTEM, WHICH IS KIND OF AN ADAPTED
CLONE OF A UNIX OPERATING PROGRAM
 LINUX IS THE KERNAL, THE PROGRAM IN THE
SYSTEM THAT ALLOCATES THE MACHINE’S
RESOURCES TO THE OTHER PROGRAMS
THAT YOU RUN.
 THE KERNEL IS AN ESSENTIAL PART OF AN
OPERATING SYSTEM.,BUT USELES BY
ITSELF, IT CAN ONLY FUNCTION IN THE
CONTEXT OF A COMPLETE OPERATING
SYSTEM.
 LINUX IS NORMALLY USED IN COMBINATION
WITH THE GNU OPERTING SYSTEM, WHOLE
SYSTEM IS BASICALLY GNU WITH LINUX
ADDED, OR GNU/LINUX. ALL THE SO-CALLED
“LINUX” DISTRIBUTED ARE REALLY
DISTRIBUTIONS OF GNU/ LINUX.
 EXAMPLE:-RED HAT, UBUNDU, FEDORA, ETC
SOLARIS
 IT IS UNIX OPERATING SYSTEM ORIGINALLY
DEVELOPED BY SUN MICROSYSTEM.
ORACLE SOLARIS, AS IT NOW KNOW, HAS
BEEN OWNED BY ORACLE CORPORATION
ORACLE’S ACQUISITION OF SUN IN JAN 2010
 IT IS KNOWS FOR ITS
SCALEBILITY,ESPECIALLY ON SPARC
SYSTEM, AND FOR ORIGINATING MANY
INNOVATIVE FEATURES SUCH AS DTRACE,
ZFS AND TIME SLIDER.SOLARIS SUPPORTS
SPARC-BASAD AND X86- BASED
WORKSTATIONS AND SERVERS FROM SUN
AND OTHER VENDORS, WITH EFFORTS
UNDERWAY TO PORT TO ADDITIONAL
PLATFORMS.
WINDOWS
 MICROSOFT WINDOWS IS A SERIES OF
GRAPHICAL INTERFACE OPERATING SYSTEM
DEVELOPED , MARKETED, AND SOLD BY
MICROSOFT.
 MICROSOFT INTRODUCED AN OPERATING
ENVIRONMENT NAMED WINDOWS ON NOV
20, 1985 AS A GRAPHICAL OPERATING
SYSTEM SHELL FOR MS-DOS IN RESPONSE
TO THE GROWING TNTEREST IN GRAPHICAL
USER INTERFACES(GUI). MICROSOFT
WINDOWS CAME TO DOMINATE THE
WORLD’S PERSONAL COMPUTER MARKET
WITH OVER 90% MARKET SHARE,
OVERTAKING MAC OS, WHICH HAD BEEN
INTRODUCED IN 1984.
S.G.ISAVE11
FUNCTIONS OF OPERATING
SYSTEM
 Process Management.
 Resource Management.
 File Management.
 Communication Management.
 Security Management.
 Memory Management.
1.Process management
 By process management OS
manages many kinds of activities :-
All process from start to shut down
Creation and deletion of user and system
processes.
2. Memory Management
 The major activities of an
operating regard to memory-
management are:-
Decide which process are loaded into memory
when memory space becomes available.
Allocate and deallocate memory space as needed.
3.File Management
 The file management system
allows the user to perform such
tasks:-
Creating files and directories
Renaming files
Coping and moving files
Deleting files
4.Security Management
 By security management OS
manages many tasks such as:-
Alert messages
Dialogue boxes
Firewall
Passwords
5.Command Interpreter
 A command interpreter is an
interface between system and
the user. There are two types of
user interface:-
Command line
Graphical user interface
Contd……
 With a command line user interface the user
interact with the OS by typing command to
perform specific tasks
 With a graphical user interface the user
interacts with the OS by using a mouse to access
windows icons and menus
