Overview of various types of operating system

  1. 1. OPERATING SYSTEM OVERVIEW
  2. 2. Presented By
  3. 3. Operating System An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs Introduction
  4. 4. • Single- and multi-tasking • Distributed • Templated • Embedded • Real-time • Library Types of OS
  5. 5.  Real Time Operating System • An operating system (OS) intended to  serve real-time application requests • An RTOS has an advanced algorithm  for scheduling.
  6. 6. Evolution of Operating Systems  A major OS will evolve over time for a  number of reasons:
  7. 7. Evolution of Operating Systems   Stages include:
  8. 8. Kernel A kernel  connects the  application  software to  the hardware  of a  computer.
  9. 9. Functions of OS • Process Management • Memory management • I/O Device management • File system • Protection and Security • Network management •  Device drivers • User Interface
  10. 10. Memory is expanded to hold three, four, or more programs and switch among all of them Operating System Structure
  11. 11. • Can be used to handle multiple interactive jobs • Processor time is shared among multiple users
  12. 12. Examples Open source - Based on open, published source code – UNIX and Linux Proprietary - Closed – Apple Macintosh Hybrid - Some elements open, some elements closed – Microsoft 13
  13. 13. Causes of Errors • Deadlocks – it is possible for two or more programs to be hung up waiting for each other • Improper synchronization – a program must wait until the data are available in a buffer
  14. 14. • Program development • Program execution • Access I/O devices • Controlled access to files • System access • Error detection and response • Accounting
  15. 15. Advantages of OS • Easy to use • User friendly • Intermediate between all hardware's and software's of the system • No need to know any technical languages • Its the platform of all programs
  16. 16. Conclusion • Without an operating system the computers cannot run the application and we cannot do work in the computer. • Therefore operating system is very important for using computer.
