NET - NET Architecture
NET Architecture is a solution for scanning across local networks.
What does it do?
Enables Sharing a scanner on a network. Enables scanning to a Designated Scan
Folder on another computer. NET Architecture allows a a scanner to scan to a client PC in a single
coherent and secure process. The client does not need to expose or share his local hard disk as the
system can be set up for authorized transfer to the client.
Example of usage - a company that needs to create digital documents of its drawing archive, can send the
drawings to a service bureau that scans all the documents directly to the client (company) file server
allowing immediate feedback from the client and prevents digital distribution of confidential documents
outside the client company. NET Architecture also allows users in a company to use a scanner, from their
own PC workstations al-though the scanner is physically placed elsewhere. It only need to be on the same
LAN. In this way a single scanner is "shared" throughout the company.
Noise
A term used to describe the occurrence of pixels that contain random colors within an image.
Original
The paper, negative, slide, or film to be scanned.
