The correct answer is (A) Scanner.
A scanner is a device that converts physical documents, such as text and images, into digital format that can be stored and processed on a computer. It works by capturing the visual information from a document and then translating it into a digital form that a computer can understand and manipulate.
Here's how a scanner typically works:
Placement : You place the document you want to scan on the glass surface of the scanner.
Scanning process : When you initiate the scanning process, the scanner's light source illuminates the document. An image sensor, usually a CCD (Charge-Coupled Device) or CIS (Contact Image Sensor), moves across the document to capture the reflected light from the document.
Conversion : The reflected light is converted into electrical signals that are then processed to form a digital image. This digital image can be saved on your computer in various formats like JPEG, PDF, or TIFF.
Storage : Once scanned, the digital image can be stored on your computer's hard drive, shared via email, or uploaded to cloud services for easy access.
Scanners are essential tools in both professional and personal settings for digitizing documents, ensuring quick and easy sharing, backup, and archival, ceasing the need for extensive physical storage.
