Operating System Notes PDF FAQs
What is an Operating System ?
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs.
Some popular Operating Systems include Linux Operating System, Windows Operating System, VMS, OS/400, AIX, z/OS, etc.
What are the functions of Operating Systems ?
- Memory Management
- Processor Management
- Device Management
- File Management
- Security
- Control over system performance
- Job accounting
- Error detecting aids
- Coordination between other software and users
What are the types of Operating Systems ?
- Batch OS: A set of similar jobs are stored in the main memory for execution. A job gets assigned to the CPU, only when the execution of the previous job completes.
- Multi-programming OS: The main memory consists of jobs waiting for CPU time. The OS selects one of the processes and assigns it to the CPU. Whenever the executing process needs to wait for any other operation (like I/O), the OS selects another process from the job queue and assigns it to the CPU. This way, the CPU is never kept idle and the user gets the flavor of getting multiple tasks done at once.
- Multitasking OS: Multitasking OS combines the benefits of Multi-programming OS and CPU scheduling to perform quick switches between jobs. The switch is so quick that the user can interact with each program as it runs.
- Time Sharing OS: Time-sharing systems require interaction with the user to instruct the OS to perform various tasks. The OS responds with an output. The instructions are usually given through an input device like the keyboard.
- Real Time OS: Real-Time OS are usually built for dedicated systems to accomplish a specific set of tasks within deadlines.
