===A scanner is an input device that scans documents such as photographs and pages of text. When a document is scanned, it is converted into a digital format. This creates an electronic version of the document that can be viewed and edited on a computer. === ===Most scanners are flatbed devices, which mean they have a flat scanning surface. This is ideal for photographs, magazines, and various documents. Most flatbed scanners have a cover that lifts up so that books and other bulky objects can also be scanned. Another type of scanner is a [|sheet-fed scanner], which can only accept paper documents. While sheet-fed scanners cannot scan books, some models include an [|automatic document feeder], or ADF, which allows multiple pages to be scanned in sequence. === ===Scanners work in conjunction with computer software programs, which import data from the scanner. Most scanners include basic scanning software that allows the user to configure, initiate, and import scans. Scanning plug-ins can also be installed, which allow various software programs to import scanned images directly. For example, if a scanner plug-in is installed for Adobe Photoshop, a user can create new images in Photoshop directly from the connected scanner. ===

===The CCD barcode scanner is a scanner that has no moving parts.CCD stands for Charged-Coupled Devise Scanner. The scanner has a light source that when pointed to an object or barcode, it illuminates that image. The image is usually a barcode. Once the barcode is illuminated, a reflection is created and the barcode scanner reads that image. The barcode scanner is connected to a PC or Mac and the CCD scanner then sends the sequence of numbers and/or letters to the PC or Mac to populate the field of entry.===
