To Sum Up


                          Computer system is made up of two types of components: hardware and software.
                          All the physical components of a computer system are called hardware.

                          A computer accepts data and instructions from you through input devices.
                          The CPU is the brain of the computer.

                          Output is the information obtained after processing of data which the user receives
                          through output devices.
                          Storage devices are used to store data for future use.
                          The 3D camera is a real-sense device which is able to recognise faces and use that
                          capability to log in to devices like smartphones or laptops.
