    Study Notes

    Introduction

    • Computer science is the operating system for all innovation
    • Operating system is a collection of software that manages a computer`s hardware and provides services for computer programs
    • OS is vital component of system software in a computer system
    • OS is interface between user and computer hardware
    • OS performs basic tasks such as file management, memory management, handling input and output, and controlling peripheral devices

    Applications of Operating System

    • Key activities: security, error detection, control over system performance, job accounting, booting, coordination between other software and users
    • Security and error detection: Prevents unauthorized access; handles a variety of internal and external hardware errors such as memory error, or a device failure or malfunction
    • Control over system performance: Collects statistics on various resources, monitors performance parameters such as response time, recording delays
    • Job accounting: Keeps track of time and resources used by various jobs and users
    • Booting: Process of starting or restarting a computer
      • Cold booting: Starting after being switched off completely
      • Warm booting: Restarting the machine
    • Coordination: Enables coordination of hardware components, coordination of and assignment of compilers, interpreters, assemblers and other software to the various users

    Firmware

    • Combination of firm and software
    • Installed directly onto hardware during manufacturing
    • Used to run user programs on the device
    • Can be thought of as the software that enables hardware to run, such as the BIOS (Basic Input/Output System)
    • Considered as software for hardware
    • Stored in non-volatile memory
    • Provides instructions to help hardware startup, communicate with other devices, and perform basic input/output functions.

    Advantages of Operating System

    • Creates an abstraction, hiding details of hardware
    • Easy to use with a GUI
    • Offers an environment for users to execute programs/applications
    • Makes the computer system convenient to use
    • Acts as an intermediary among applications and hardware components
    • Provides computer system resources in an easy-to-use format
    • Acts as an intermediary between hardware and software in the system

    Disadvantages of Operating System

    • If any issue occurs in the OS, you may lose all the contents stored in your system
    • Expensive for small organizations, adding a burden on them
