                  Computer safety refers to the protection of computer-based resources against unauthorised use
                  or physical damage.

                  You know that computers are expensive, so if you have a computer, you must take care of it.
                  It is not difficult to keep your computer healthy and in good working condition. Maintaining a
                  computer involves three things:

                      ✶ Keeping it physically clean
                      ✶ Protecting it from malware
                      ✶ Backing up your important files

                      KEEPING YOUR COMPUTER PHYSICALLY FIT

                  The first step in computer safety is to keep your computer physically fit. Dust can potentially
                  destroy the parts of your computer. By cleaning your computer regularly, you can maintain its
                  performance and avoid expenses on repairs.

                  Cleaning the computer means cleaning different parts of the computer system like:

                        1.   Cleaning the Keyboard
                             Cleaning  the  keyboard  is an  important  task  for
                             keeping your computer physically fit. Dust and dirt
                             on the keyboard do not look nice and can prevent

                             your keyboard  from working  properly.  Particles
                             such as dust, food, liquid, etc.,  can get stuck
                             underneath the keys, which can prevent  the keys
                             from functioning properly. Use a soft cloth to clean
                             the keys of the keyboard.
