    As you know, a computer requires an operating system to work. Without it, we cannot
                      start a computer and work on it. An operating system is a system software that controls

                      all the activities of a computer and provides an easy interface to the computer. In this
                      chapter, we will learn about The Windows 11 operating system. Some other operating
                      systems are Linux, Unix, Mac OS X and MS DOS.

                                WINDOWS 11

                      Windows 11 is a new generation of operating system launched by Microsoft in 2021. It
                      comes with a completely new design and interface. It has a Graphical User Interface (GUI)

                      which allows users to interact with computers through buttons, icons or dialog boxes.

                                     Which was the first operating system invented?

                      FEATURES OF WINDOWS 11

                      Some features of Windows 11 are:

                         It is a user-friendly operating system.
                         It has a GUI which means you do not need to remember all the commands.

                          It allows us to download and install Android apps from the Amazon Appstore
                         through the Microsoft Store.
                         It has a new style of Start Menu: everything is arranged under different tiles.

                         It allows us to run several programs at the same time.
                         It allows us to create multiple desktops.

                      STARTING WINDOWS

                      When we switch on the computer, the Windows operating system is loaded into the
                      computer’s memory. The process of loading
                      the operating system after the computer is
                      switched  on is  known as  booting. During
                      booting, the computer performs necessary
                      actions which makes it ready to use. After
                      booting, a screen appears which is known
                      as the  login  screen.  After some  time,
                      the screen appears,  which is called the

                      desktop. Let’s learn about the desktop and
                      its components.
