    Study Notes

    Operating System's Role in Managing Hardware

    • The operating system manages computer hardware, allocating resources and controlling access to hardware devices.

    Process Management

    • The operating system performs process scheduling, allocating CPU time and resources to running programs.
    • It manages process creation, execution, and termination, ensuring efficient use of system resources.

    Memory Management

    • The operating system enables larger programs to run without fully loading into memory by using virtual memory, dividing the program into smaller chunks, and swapping them between RAM and disk storage.

    File Management

    • The primary role of the operating system in managing files is to provide a file system, organizing files into a hierarchical structure, and controlling access to files.

    Device Drivers

    • Device drivers are software components that allow the operating system to interact with hardware devices, enabling communication and control.

    User Interface

    • The graphical user interface (GUI) allows users to interact with the computer through graphical elements like windows, icons, and menus.

    User Authentication

    • The primary function of user authentication is to verify the identity of users, ensuring that only authorized users have access to system resources.

    Network Communication

    • The operating system's networking component supports network communication, allowing computers to connect and share resources over local networks or the internet.

    Command-Line Interface

    • The command-line interface (CLI) provides a text-based interface for users to interact with the system, executing commands and scripts.

    Error Handling and Recovery

    • The main function of error handling and recovery mechanisms is to detect and respond to system errors, ensuring system stability and reliability.
