Why learn Operating Systems?
Here are the reasons for learning Operating systems:
- Allows you to hide details of hardware by creating an abstraction
- Easy to use with a GUI
- Offers an environment in which a user may execute programs and applications
- Operating System acts as an intermediary among applications and the hardware components
- It provides the computer system resources in easy to use formats
What are the applications of the Operating System?
Following are some of the important activities that an Operating System performs:
- Security: Operating system prevents unauthorized access to programs and data.
- Controls the performance of a system: Recording delays between a request for a service and response from the system.
- Job accounting: You can keep track of the time and resources.
- Error detecting aids: OS helps to trace error messages and other debugging and error detecting aids.
- Helps to Coordinate between other software: Coordination and assignment of compilers, interpreters, assemblers, and other software.
Features of Operating System:
Here is a list of commonly found important features of an Operating System:
- Protected and supervisor mode
- Allows disk access and file systems device drivers networking security
- Program execution
- Memory management
- Handling I/O operations
- Manipulation of the file system
- Error Detection and handling
- Resource allocation
- Information and Resource Protection
