◦  Memory Card: It is commonly known as a multimedia memory card. It is
                       very small in size, usually 1–1.5 inches. These are used in mobile phones and
                       digital cameras. You need to have a card reader to read stored data on a
                       memory card.

                   i +   NEW TRENDS IN HARDWARE

                  Some hardware devices with new technology are already available, and some are in 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 has a wireless version available. They work with
                                             the help of radio frequency (RF), infrared (IR), or Bluetooth technology.



                  Virtual Keyboard

                  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 that  is able to recognise  faces and
                                           use that capability to log in to devices like smartphones or laptops. 3D
                                           cameras can also measure distances between items or even scan objects
                                           for 3D printing.
