Question

what is scanning?explain it in your words.​

Answer 1

Answer:

1. A scanner is a device that captures images from photographic prints, posters, magazine pages, and similar sources for computer editing and display.
2. Scanners come in hand-held, feed-in, and flatbed types and for scanning black-and-white only, or color. Very high resolution scanners are used for scanning for high-resolution printing, but lower resolution scanners are adequate for capturing images for computer display.
3. Scanners usually come with software, such as Adobe's Photoshop product, that lets you resize and otherwise modify a captured image.

• An image scanner—often abbreviated to just scanner, is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image.
• Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning.
• Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.
• Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical.
