When a key is pressed, it signals the computer to display the corresponding character or
                     function on the screen instantly, ensuring accurate input.

                                   Mouse: A mouse is a common input device used to control the pointer (cursor)
                                 on a computer screen. It can be either wired or wireless, often connecting through
                                 Bluetooth. A standard mouse has two buttons (left-click and right-click) and a
                                 scroll wheel. The buttons let you perform different tasks in software. The mouse
                                 helps you select options, move the cursor, and drag and drop files or items. The
                                 scroll wheel lets you quickly move through long documents or web pages.
                     Scanner: A scanner  is an  input device that  changes  physical
                     documents, pictures, and photos into digital files. It allows users to
                     capture  handwritten  or printed  materials and send them to a
                     computer, where they can be saved, edited, or shared.
                                               Touchpad: Touchpads are  an alternative
                                               to the traditional mouse, commonly found on laptops. They allow
                                               users to control the cursor’s movement on a screen by using their
                                               fingers or a stylus on a flat surface.
                     Light Pen: A light pen is a pen-shaped pointing device with a light-
                     sensitive tip that lets users interact directly with a computer screen.
                     By pointing, users can select or draw on the screen.


                                       Microphone: A microphone turns sound into digital audio so it can be saved
                                       or processed by a computer. It captures sound and is important for activities
                                       like recording, making voice calls, and recognising speech.


                     Barcode Reader: A barcode is a set of parallel lines that helps
                     identify products. Most packages have these barcodes, which can
                     be easily read by barcode scanners. The scanner shines light on
                     the barcode and detects the light that bounces back. The scanned
                     information is then saved on a computer, often used for invoicing.
                                          Magnetic Ink Character Recognition: Bank
                                        account numbers and other details on cheques are printed with a special
                                        magnetic ink, which can be read by Magnetic Ink Character Recognition
                                        (MICR).  This technology helps verify  whether  a  cheque  is genuine  or
                                        counterfeit.

                       Digital  Camera:  A digital camera can serve as an input device by
                     capturing visual information in the form of images and videos. It can be
                     easily transferred  to a computer for further  processing, analysis, or
                     storage.

                                         Graphics Tablet: A graphics tablet, is a type of input device that
                                       consists of a flat, rectangular surface with a stylus (digital pen) used for
                                       drawing, writing, and interacting with graphical applications. It also takes
                                       handwritten work as an input and converts it into digital form.
