                 New Trends in Hardware




                 Some hardware devices with new technology  are already available and  some  are                            EXPLORE MORE (New Trends in Hardware)
                 under the process of development. Let’s discuss some of them.


                   Wireless Devices


                 Earlier, all hardware devices were connected
                 to the CPU box through a wire. These days,

                 almost  every type  of hardware offers a
                 wireless options. They  work with the  help                                                              117

                 of radio frequency (RF), infrared  (IR)  or                            Wireless devices
                 Bluetooth technology.

                                                           A virtual  keyboard is operated by  typing  on a
                                                           detectable surface rather than pressing physical

                                                           keys. It is actually a software component because
                                                           it is not a physical part.

                  3D Camera

                 3D camera is a real-sense  device which is able

                 to recognise faces  and  use that capability
                 to log in into their devices like smartphones

                 or laptops.  3D cameras  can  also  measure
                 distances between items or even scan objects

                 for 3D printing.                                                        3D Camera
