\"Infographic:<\/figure>\n

Every computer and smartphone needs an operating system (OS)<\/strong>. It is the master software that starts when you switch the device on and manages everything else.<\/p>\n

The OS as a manager<\/h2>

Think of a busy restaurant. The kitchen (hardware) has cooks, ovens and fridges. The customers (apps) place orders. The manager<\/strong> makes sure orders reach the right cook, nothing clashes, and everything runs smoothly. The OS is that manager.<\/p>\n

What does an operating system do?<\/h2>
  • Manages the processor:<\/strong> decides which app gets to use the CPU and when, so many apps can run at once.<\/li>
  • Manages memory:<\/strong> gives each app space in RAM and keeps them from interfering.<\/li>
  • Manages storage:<\/strong> organises files and folders.<\/li>
  • Controls devices:<\/strong> communicates with the keyboard, screen, camera and printer through drivers.<\/li>
  • Provides the interface:<\/strong> the home screen, windows, icons and menus you use.<\/li>
  • Keeps you secure:<\/strong> handles passwords, permissions and updates.<\/li><\/ul>\n

    The kernel<\/h2>

    At the heart of every OS is the kernel<\/strong>, the core program that talks directly to the hardware.<\/p>\n

    Popular operating systems<\/h2>
    • Windows<\/strong> (Microsoft): the most widely used desktop OS.<\/li>
    • macOS<\/strong> (Apple): used on Mac computers.<\/li>
    • Linux:<\/strong> free and open-source; it runs most of the world’s web servers and supercomputers.<\/li>
    • Android<\/strong> (Google): based on Linux, it is the most used mobile OS worldwide and dominant in India.<\/li>
    • iOS<\/strong> (Apple): runs iPhones.<\/li><\/ul>\n

      Open source vs closed source<\/h2>

      Open-source systems like Linux publish their code so anyone can study and improve it. Closed-source systems like Windows and iOS keep their code private.<\/p>\n

      Why do updates matter?<\/h2>

      OS updates fix bugs, close security holes and add features. Keeping your OS updated is one of the simplest ways to stay safe online.<\/p>","protected":false},"excerpt":{"rendered":"
