3. Programs
A program is a set of instructions a computer follows in order to
perform tasks

4. Introduction of system software
 System software is a type of computer software that is
designed to run a computer’s hardware and application
software
 Most system software works in the background and is not
controlled by the end user
 It is used to start and run computer systems and
networks
 System software consists of low level program that
interact with the computer at a very basic level

5. Features of system software
 Ease of use
 More powerful features
 High quality and reliability
 Better security
 Multiplatform capability
 Compatibility with other software
 Web and mail enabling
 Network and mobile computing

6. Types of system software
 Operating system
 Utilities
 Compilers
 Interpreter
 Assemblers
 Debuggers

7. Operating system(OS)
 The operating system (OS) is the best-known example of
system software. The OS manages all the other programs
in a compute
 An operating system (OS) is a set of programs
containing instructions that coordinate all the activities
among computer hardware devices
 Helps the applications run, and controls the display and
the keyboard.
 Example: Linux, MAC OS, Microsoft Windows,etc

9. Function Of OS
 Job Management
 Data Management
 Online processing
 Process Scheduling
 Memory Management
 I/O Management
 Serves as resource manager

10. Classification of Operating
System
 Desktop Operating system
 Server Operating system
 Mainframe Operating system
 Multi User Operating system
 Multi Processing: (more than 1 CPU used for
processing of data) Operating system
 Multi Tasking:(1 CPU; Cooperative & Preemptive
mechanism is used) Operating system
 Multithreading :(Different part of the program run
concurrently)
 Real Time Operating system

11. Utilities software
 It is a program that performs a very specific task, usually
managing managing system resources
 It differs from application mostly in terms of size and
complexity
 Examples:
Antivirus
Disk Cleaner
Data compression
Disk compression
Dackup software

12. Compilers and Interpreters

13. Conclusion
 Software-based protection systems are coming into
common use, with advantages in both performance
and portability
 Operating system are the most important programs
that runs on a computer
