WHY DO WE NEED AN OPERATING SYSTEM?

                  An Operating System (OS) is essential for a computer to
                  function. The OS acts as a bridge between the user and
                  the computer hardware. The OS controls and manages
                  the computer’s hardware and software to ensure they
                  work together smoothly. Without an OS, you wouldn’t
                  be able to run applications like web browsers,  word

                  processors, or games. The OS provides the platform
                  that these programs need to operate.

                     FUNCTIONS OF AN OPERATING SYSTEM


                  When we turn on the computer, the operating system begins its job. After the computer starts up
                  (a process called booting), the operating system gets loaded into the computer's memory. Once
                  it's loaded, it takes charge of managing and running all the computer's tasks.
                  An operating system performs many important functions. Some of these are:
                                                                              Boost Bits
                      Arranging Files and Folders: The operating
                     system helps you to organise the files and
                                                                        The  process of loading  an  operating
                     folders on the computer. It also tracks when       system is called booting the system.
                     you create, copy, or change a file.

                      Assigning Tasks to the CPU: The operating system tells the CPU what tasks to do based on
                     your instructions. It also helps control the execution of the tasks. It also ensures the CPU has
                     everything to finish the tasks.
                      Managing Memory: The operating system helps manage the computer's memory. It keeps

                     track of which parts of the memory are being used by programs and which parts are free.
                     It also gives memory to files and folders. When we delete something, the operating system
                     frees up that memory so it can be used again.
                      Managing Resources: An operating  system keeps track  of the  hardware  and  software
                     requirements of the processes. It works as a manager of the resources and allocates them to

                     different programs.
                      Managing Devices: The OS controls all the devices you connect to your computer, such as a
                     mouse, keyboard, or printer. It makes sure these devices work correctly with your computer
                     and follow your instructions. For example, when you type using the keyboard, the OS helps
                     the computer understand and display what you are typing on the screen.

                      Security: The OS has built-in security features to protect your computer from unauthorised
                     access. This means it helps keep your programs and files safe from people who should not
                     be able to access them. It controls who can log in and what actions they can perform on your
                     computer.
