The scanner is a device that can transfer typed or hand written texts, graphs, diagrams and photographs to the computer. Instead of making a duplicate copy on paper of the required data or photograph, scanner stores them in the memory of computer.
Scanners find their use in a wide variety of jobs. They can be used for storing photographs and important documents in their original forms. They may also be used to take in enormous text material that otherwise would be very tedious to type manually.
Two types of scanners mostly used:
- FLATBED scanner
- HANDHELD scanner
