A scanner is a device that captures images from photographic prints, posters, magazine pages, and similar sources for computer editing and display. Very high resolution scanners are used for scanning for high-resolution printing, but lower resolution scanners are adequate for capturing images for computer display.

Considerations for Scanner Selection

• Centralized or De-Centralized Scanning.
• Document Type.
• Cost/Speed/Size.
• Imaging Quality.
• Software Compatibility.
• Service Cost/Ease of Service/Warranty.

A scanner is a device usually connected to a computer. Its main function is to scan or take a picture of the document, digitize the information and present it on the computer screen.

Handheld scanners use a sensor on the end of a wand, which the user drags over the surface of a document to scan text or images. Handheld scanners produce lower-quality images, but are more portable than flatbed scanners. Negative scanners are another specialized option for photographers.

Scanners have many purposes which include copying, archiving, and sharing photos. The device captures images from print papers, photos, magazines, etc., and transfer them to the computer. It creates a digital copy of your important documents.

Scanners are people who like to explore everything, try out many different careers and, as the title suggests, who “refuse to choose”. A scanner type personality has a hard time focusing on one single occupation, hobby or career. scanners would like to do everything at once or, at least do everything at least once.

Scanners operate by shining light at the object or document being digitized and directing the reflected light (usually through a series of mirrors and lenses) onto a photosensitive element. In most scanners, the sensing medium is an electronic, light-sensing integrated circuit known as a charged coupled device (CCD).

High-quality digital scanning relieves the burden of filing paper forms and simplifies document sharing. Using special software, you can extract the text from scanned documents, making them easier to search. Scanning has also proven a boon to photographers, who can retouch and repair old photographs digitally.

The biggest disadvantage of all microphones is the human element. A microphone is only as good as the person using it. If you place the microphone in a bad location, for instance, you won’t get the best recording. Or if you use the wrong microphone for a certain application, it won’t be as effective.
