Device that converts any type of printed information into digital pulses:
The correct answer is Scanner.
Here is a detailed explanation:
Definition of a scanner:
A scanner is a device that converts physical documents or images into digital format by scanning and capturing the information. It uses optical sensors to read the printed information and convert it into a series of digital pulses.
Working of a scanner:
1. Optical sensors: Scanners use optical sensors to detect and capture the printed information. These sensors work by reflecting light off the document and measuring the reflected light intensity.
2. Image capture: The scanner captures the reflected light and converts it into a digital image.
3. Optical character recognition (OCR): Scanners often include OCR technology, which can recognize and convert printed text into editable digital text.
4. Digital output: The scanned document or image is then converted into a digital format, such as a PDF or image file, which can be stored, edited, or shared electronically.
Advantages of using a scanner:
- Preservation of physical documents: Scanning allows you to create digital copies of important documents, reducing the need for physical storage and preserving the information for future reference.
- Easy sharing and distribution: Digital files can be easily shared via email, cloud storage, or other electronic means, making it convenient to distribute information.
- Editable text: With OCR technology, scanned documents can be converted into editable text, enabling easy modifications or extraction of specific information.
- Improved accessibility: Digital documents can be easily accessed and read by devices that support text-to-speech or other accessibility features.
In conclusion, a scanner is the device that converts any type of printed information into digital pulses. It is a useful tool for digitizing and managing physical documents or images.
