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.
Computer networks enhance how we communicate with each other by using various electronic methods like email, instant messaging, online chat, voice and video calls, and video conferencing. Networks also enable the sharing of computing resources. For example, you can print a document on a shared printer or use shared storage devices.
Barcode reader. A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. [ 1] Like a flatbed scanner, it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals. Additionally, nearly all barcode readers contain ...
Scanner Access Now Easy ( SANE) is an open-source application programming interface (API) that provides standardized access to any raster image scanner hardware ( flatbed scanner, handheld scanner, video- and still-cameras, frame grabbers, etc.). The SANE API is public domain. It is commonly used on Linux .
The standard addresses all of the issues that an application using a scanner needs to be concerned with. Functions include but are not limited to selecting, installing, and configuring a new scanner; setting scanner-specific parameters; scanning, reading and writing files, and fast image scaling, rotating, displaying, and printing. Drivers have ...
Shared file and printer access require an operating system on the client that supports access to resources on a server, an operating system on the server that supports access to its resources from a client, and an application layer (in the four or five layer TCP/IP reference model) file sharing protocol and transport layer protocol to provide that shared access.
