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
