Cleaning the computer involves cleaning different parts of the computer system, such as:
                 1.  Cleaning the Keyboard

                      Cleaning the keyboard is an important task to keep your computer
                    in  good  physical  condition. Dust  and  dirt  on  the  keyboard  not
                    only look unattractive but can also prevent it from functioning
                    properly. Particles such as dust, food, liquid, etc., can get stuck
                    underneath the keys, which may cause them to stop functioning
                    properly. Use a soft cloth to clean the keys of the keyboard.
                 2.  Cleaning the Mouse

                      Cleaning  the mouse  is an important  step  in keeping  your computer
                    physically fit. There are two main types of mouse: optical and mechanical.
                      An optical mouse is an advanced computer pointing device that uses a
                    light-emitting diode (LED) and an optical sensor. This type of mouse does

                    not require any internal cleaning since there are no  rotating parts;
                    however, they become sticky over time as dust collects near the  light
                                                                                                    Optical mouse
                    emitter. This can cause erratic cursor movement or prevent the mouse
                    from working properly. You should clean the surface of the mouse and the
                    mouse pad regularly to prevent dust from accumulating on the mouse.
                      Mechanical mouse uses a rubber ball that makes contact with wheels
                    inside the unit when it is rolled on a pad or desk. This type of mouse is

                    especially susceptible to dust and particles that can accumulate inside
                    the mouse, which can make it difficult to track or move properly. If the
                    mouse pointer does not move smoothly, you will need to clean the rubber       Mechanical mouse
                    ball.
                 3.  Cleaning the Monitor

                      Cleaning the monitor is also a crucial step in keeping your computer physically fit. Dirt, fingerprints,
                    and dust can make your computer screen difficult to read; however, it is easy to clean your screen
                    when needed. Before cleaning, you should:
                      Shut down the computer.
                      Unplug the monitor from the power source.

                      If you are using a laptop, shut it down.
                      Use a soft and clean cloth to wipe the screen.
                       Do not spray any liquid directly onto the screen. The liquid could

                      leak into the monitor and damage the internal components.               Cleaning the Monitor


                                                             Tech Fact

                    Do not use glass cleaner to clean a monitor. Many screens have anti-glare coatings that can
                                                   be damaged by glass cleaners.
