• What is the purpose of system programs? System programs can be thought of as bundles of useful system calls. They provide basic functionality to users so that users do not need to write their own programs to solve common problems.

  Moreover, Operating System also provides certain services to the computer system in one form or the other. The Operating System provides certain services to the users which can be listed in the following manner:

  1. Program Execution: The Operating System is responsible for the execution of all types of programs whether it be user programs or system programs. The Operating System utilizes various resources available for the efficient running of all types of functionalities.
  2. Handling Input/output Operations: The Operating System is responsible for handling all sort of inputs, i.e., from the keyboard, mouse, desktop, etc. The Operating System does all interfacing most appropriately regarding all kind of Inputs and Outputs. For example, there is a difference in nature of all types of peripheral devices such as mouse or keyboard, then Operating System is responsible for handling data between them.
  3. Manipulation of File System: The Operating System is responsible for making decisions regarding the storage of all types of data or files, i.e., floppy disk/hard disk/pen drive, etc. The Operating System decides as to how should the data be manipulated and stored.
  4. Error Detection and Handling: The Operating System is responsible for the detection of any types of error or bugs that can occur while any task. The well-secured OS sometimes also acts as a countermeasure for preventing any sort of breach to the Computer System from any external source and probably handling them.
  5. Resource Allocation: The Operating System ensures the proper use of all the resources available by deciding which resource to be used by whom for how much time. All the decisions are taken by the Operating System.
  6. Accounting: The Operating System tracks an account of all the functionalities taking place in the computer system at a time. All the details such as the types of errors occurred are recorded by the Operating System.
  7. Information and Resource Protection: The Operating System is responsible for using all the information and resources available on the machine in the most protected way. The Operating System must foil an attempt from any external resource to hamper any sort of data or information.
