    Study Notes

    Learning Objectives

    • Understanding key operating system concepts is crucial.
    • Recognizing the categories of operating systems enhances comprehension.
    • Identifying the primary roles of an operating system is fundamental.
    • Knowledge of the five major components of operating systems is essential.
    • Familiarity with current general-purpose operating systems is beneficial.

    Introduction to Operating Systems

    • Computers execute three primary tasks: Input, Processing, and Output.
    • The operating system (OS) controls and coordinates hardware functions.

    Features of Operating Systems

    • Provides a user interface for interaction.
    • Manages storage effectively.
    • Oversees process and service management.
    • Handles memory and Input/Output management.
    • Ensures security and resource protection.
    • The kernel is central to the OS operations.

    Operating System Categories

    • Classified broadly into Single-tasking vs. Multitasking, Single-user vs. Multiuser, and General-purpose vs. Real-time systems.

    Single-Tasking vs. Multitasking

    • Single-tasking OS can handle one process at a time; common in embedded systems.
    • Multitasking OS rapidly switches between processes in memory.
    • Cooperative multitasking allows processes to control CPU until termination.
    • Preemptive multitasking keeps the OS in control at all times.

    Server Operating Systems

    • Designed for fault tolerance, allowing recovery from failures.
    • Supports clustering to enable multiple servers to function as a single system.
    • Load-sharing clusters distribute client requests among servers.
    • Hot swapping allows component replacement without system shutdown.
    • Scalability facilitated by hot adding components during runtime.

    Boot Procedure

    • Firmware, stored in non-volatile memory, performs diagnostics and boots the OS.
    • BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) initializes booting.
    • BIOS performs hardware tests (POST) and loads the OS.
    • CMOS memory stores BIOS configuration, accessible via the BIOS setup screen.

    Process and Service Management

    • A process is a loaded program executed by the CPU.
    • Windows Task Manager displays all running processes, including background processes and essential system functions.

    Memory and I/O Management

    • Memory managed by a dedicated memory manager in kernel mode.
    • OS allocates and deallocates memory as processes start and finish.
    • I/O management prevents simultaneous access to devices by multiple processes.
