User Interface
















                         Imagine  your  computer's  user  interface  as  a

                         helpful tour guide. It offers a method for you to

                         communicate  with  the  system  using  either  text

                         commands or graphical icons.

                          Performance










                      Consider  your  operating  system  to  be  the
                      performance  traffic  management  for  your


                      computer. Assuring that no one uses up all the
                      resources,  it  organises  and  guides  the  flow  of

                      tasks.  The  operating  system  makes  sure  that

                      your  computer's  power  is  used  properly  and

                      efficiently  to  prevent  lags  and  jams,  the  same

                      way traffic lights keep cars moving smoothly.
