Digital Versatile or Video Disc (DVD): DVDs have become a popular

                                           medium for storing information and videos on computers. Similar to
                                           CDs, DVDs have  a  greater  storage  capacity,  making them ideal for
                                           storing and viewing movies and other data.




                    Blu-ray Disc: A Blu-ray disc is an optical storage medium designed for
                    holding  large  amounts  of  data and  playing  high-definition videos.  It
                    differs from DVDs primarily in its much greater storage capacity.




                    Flash Drive: A flash drive is a compact, portable storage device with a Universal Serial Bus
                    (USB) connector.

                                          •  Pen Drive: A pen drive is a portable storage device that is easy
                                             to carry in a pocket and can be plugged into any computer with a
                                             USB port. It offers storage capacities of up to 1 TB.



                    •   Memory Card: It is referred to as a multimedia memory card; it is
                       a very small storage device (typically 1–1.5 inches) used in mobile
                       phones and digital cameras. A card reader is needed to access data
                       stored on a memory card.


                    NEW TRENDS IN HARDWARE
                 Advancements  in technology  have  led to  the  development  of various  innovative  hardware
                 devices. Some are already available, while others are still in development. Let us explore a few
                 of them.
                 Wireless Devices

                 Traditionally, all hardware devices were connected
                 to the CPU via wires. Today, almost every type of
                 hardware has a wireless version that operates using
                 radio frequency  (RF), infrared  (IR), or Bluetooth

                 technology.


                                                        Virtual Keyboard

                                                        A virtual keyboard allows typing on a detectable surface
                                                        instead of pressing physical keys. Though it appears to
                                                        be a hardware component, it is actually a software-based
                                                        input method.
