Study Notes

Operating System (OS) Overview

  • An Operating System (OS) is a software that manages computer hardware resources and provides common services to computer programs.

Role of an Operating System (OS)

  • Acts as an intermediary between computer hardware and user-level applications
  • Manages hardware resources such as CPU, memory, and storage
  • Provides a platform for running application software

Graphical User Interface (GUI)

  • A visual interface that allows users to interact with the operating system using graphical icons, windows, and menus
  • Enables users to interact with the computer using visual representations rather than text commands

Interface between User and Hardware

  • The OS acts as an interface between the user and the computer hardware
  • It receives input from the user, interprets it, and executes the necessary actions using the hardware
  • Provides an abstraction layer between the user and the hardware, making it easier to use the computer

Services Provided to Computer Programs

  • The OS provides an environment for computer programs to run
  • Offers services such as process management, memory management, and file management
  • Enables computer programs to interact with the computer hardware and other programs
