This dust can cause erratic cursor movement or prevent the mouse
                                                from functioning properly.  To avoid this, you should regularly
                                                clean the mouse and mouse pad surfaces.

                                                A mechanical mouse uses a rubber ball that makes contact with
                                                internal wheels when it is rolled on a pad or desktop. This type of
                                                mouse is particularly susceptible to dust and particles, which can
                                                accumulate inside and interfere with its tracking and movement.
                        Mechanical Mouse        If the mouse pointer does not move smoothly, you will need to
                                                clean the rubber ball.

                    Scanner: A scanner is used to input printed pictures and text into a computer. There are
                   various types of scanners available, and the choice of scanner depends on its intended use.
                   Some popular types of scanners include:


                      •  Hand-Held Scanner: It is a type of scanner that can be held in
                        hand and rolled over a flat image or document. It is small in size,
                        portable, and less expensive.

                                                                                                  Hand-Held Scanner
                                              •   Flatbed  Scanner:  It  is  a  type  of  scanner  that  uses  a  flat  glass
                                                 surface for scanning documents. It looks like a photostat machine.
                                                 Unlike a hand-held scanner, a flatbed scanner does not require
                                                 movement on the document.
                     Flatbed Scanner
                      •   Sheetfed Scanner:  It  is a  type  of  scanner  that  allows multiple
                         papers to be scanned at a time. In this scanner, the stack of papers
                         is placed on top and the scanner automatically scans the pages
                         one by one. It is widely used in offices.
                                                                                                    Sheetfed Scanner

                  The difference is that a flatbed scanner scans one page at a time on a glass surface, while a
                  sheet-fed scanner can automatically handle and scan a stack of papers.



                                    Webcam: A webcam  is a  digital video  camera  connected  to  a  computer,
                                    allowing you to transmit your image over the Internet. Smaller than traditional
                                    cameras, webcams are typically attached to the computer monitor or built into

                                    the device. They are widely used for video conferencing, online streaming, and
                  Webcam            virtual meetings.

                    Graphic Tablet: It allows you to directly draw on a computer screen. The
                   device consists of a flat surface upon which you can draw with an attached
                   stylus that looks like a pen.                                                       Graphic Tablet
