- 3. • INTRODUCTION TO OPERATING SYSTEM An Operating System (OS) is an interface between computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers. An operating system is the most important software that runs on a computer. Some popular Operating Systems include Linux Operating System, Windows Operating System, VMS, OS/400, AIX, z/OS, etc.
- 4. • WHAT IS OPERATING SYSTEM An Operating System performs all the basic tasks like managinge files, processes, and memory. Thus operating system acts as the manager of all the resources, i.e. Resource manager. Thus, the operating system becomes an interface between the user and the machine. It is one of the most required software that is present in the device. Some popular Operating Systems include Linux Operating System, Windows Operating System, VMS, OS/400, AIX, z/OS, etc.
- 5. • THE OPERATING SYSTEM‘S JOB Our computer's operating system (OS) manages all of the software and hardware on the computer. Most of the time, there are several different computer programs running at the same time, and they all need to access your computer's central processing unit (CPU), memory, and storage. The operating system coordinates all of this to make sure each program gets what it needs.
- 6. • IMPORTANT FUNCTIONS OF OPERATING SYSTEM •Memory Management • Processor Management • Device Management • File Management • Security • Important functions of Operating system • Control over system performance
- 7. TYPES OF OPERATING SYSTEM 1• Batch Operating system : This type of operating system does not interact with the computer directly. There is an operator which takes similar jobs having same requirement and group them into batches. It is the responsibility of operator to sort the jobs with similar needs.
- 8. 2 • MULTI-PROGRAMMING OPERATING SYSTEM •Multiprogramming Operating Systems can be simply illustrated as more than one program is present in the main memory and any one of them can be kept in execution. This is basically used for better execution of resources
- 9. 3 • MULTI-PROCESSING OPERATING SYSTEM Multi-Processing Operating System is a type of Operating System in which more than one CPU is used for the execution of resources. It betters the through out of the System
- 10. 4 • MULTI-TASKING OPERATING SYSTEM •Multiuser operating system allow simultaneous access to a computer system through two or more terminals. Although frequently associated with multiprogramming, multiuser operating system does not imply multiprogramming or multitasking. A dedicated transaction processing system such as railway reservation system that supports hundreds of terminals under control of a single program is an example of multiuser operating system.
- 11. 5 • TIME SHARING OPERATING SYSTEM •It is a form of multiprogrammed operating system which operates in an interactive mode with a quick response time. The computer processes it and a response (if any) is displayed on the user's terminal. A time sharing system allows the many users to simultaneously share the computer resources.
- 12. 6 • DISTRIBUTED OPERATING SYSTEM These types of operating system is a recent advancement in the world of computer technology and are being widely accepted all-over the world and, that too, with a great pace. Various autonomous interconnected computers communicate each other using a shared communication network. Independent systems possess their own memory unit and CPU.
- 13. 7 • NETWORK OPERATING SYSTEM •These systems run on a server and provide the capability to manage data, users, groups, security, applications, and other networking functions. These type of operating systems allow shared access of files, printers, security, applications, and other networking functions over a small private network.
- 14. 8 • REAL – TIME OPERATING SYSTEM It is another form of operating system which are used in environments where a large number of events mostly external to computer systems, must be accepted and processed in a short time or within certain deadlines. Examples of such applications are flight control, real time simulations etc. Real time systems are also frequently used in military application. A primary objective of real- time system is to provide quick response times.
- 15. 9 • LAYERED STRUCTURE OF THE OPERATING SYSTEM
- 16. CONCLUSION •Operating system have came a long way since their early days. They have evolved to support a wide range of devices and provide essential functionality for modern computing From batch processing system to mobile operating systems, each era has brought new capabilities and challenges. As Technology advances, operating System will remain at the core, enabling us to harness the power of computer in our daily lives.
