An operating system acts as a communication bridge (interface) between the user and computer hardware. The purpose of an operating system is to provide a platform on which a user can execute programs in a convenient and efficient manner. An operating
system is a piece of software that manages the allocation of computer hardware. The coordination of the hardware must be appropriate to ensure the correct working of the computer system and to prevent user programs from interfering with the proper working of the system. What is operating system ? The main task an operating system carries out is the allocation of resources and services, such as allocation of: memory, devices, processors and information. The operating system also includes programs to manage these resources, such as a traffic controller, a scheduler, memory management module, I/O programs, and a file system. Important functions of an operating system:
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:
All these services are ensured by the operating system for
the convenience of the users to make the programming task easier. All different kinds of operating system more or less provide the same services. Adapted from: What is application in operating system?An application, also referred to as an application program or application software, is a computer software package that performs a specific function directly for an end user or, in some cases, for another application.
What is the importance of operating system in computer application?An operating system is the most important software which runs on a computer. It controls the computer's memory, processes and all software and hardware. Several computer programs normally run at the same time, all of which need to access the computer's processor (CPU), memory, and storage.
How does the application interact with the operating system?The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface, such as a command-line interface (CLI) or a graphical UI (GUI).
Why is it important to have the operating system and application in between the hardware and the user?An operating system acts as a communication bridge (interface) between the user and computer hardware. The purpose of an operating system is to provide a platform on which a user can execute programs in a convenient and efficient manner.
