Operating System Objectives and Functions

Study Notes

Operating System Role

The operating system is the component of a computer system that manages and coordinates the use of hardware resources.
It acts as an intermediary between the hardware and software applications, enabling smooth operation and efficient allocation of resources.

Operating System Goals

The primary goal of an operating system is to provide an environment for running applications, ensuring that the system is used efficiently and securely.

Hardware Resources

The hardware component of a computer system provides several basic resources, including:
- Central processing unit (CPU): Executes instructions and performs calculations.
- Memory (RAM): Stores data and programs currently being used by the system.
- Secondary storage: Stores data persistently, such as hard drives or SSDs.
- Input and output (I/O) devices: Allows interaction with the system, like keyboards, mice, monitors, and printers.

System Calls

System calls are a mechanism by which applications request services from the operating system.
They enable applications to access and utilize hardware resources, ensuring proper interaction and control.

Application Programs

Application programs are software designed to perform specific tasks for users, such as word processing, web browsing, or gaming.
They rely on the operating system to access and manage hardware resources, enabling them to function effectively.
