MMR Modified Modified READ (MMR) is a compression method recommended by ITU-T T.6. Modem A device that modulates a carrier signal to encode digital information, and also demodulates such a carrier signal to decode transmitted information. MR Modified Read (MR) is a compression method recommended by ITU-T T.4. MR encodes the first scanned line using MH. The next line is compared to the first, the differences determined, and then the differences are encoded and transmitted. NetWare A network operating system developed by Novell, Inc. It initially used cooperative multitasking to run various services on a PC, and the network protocols were based on the archetypal Xerox XNS stack. Today NetWare supports TCP/IP as well as IPX/SPX. OPC Organic Photo Conductor (OPC) is a mechanism that makes a virtual image for print using a laser beam emitted from a laser printer, and it is usually green or rust colored and has a cylinder shape. An imaging unit containing a drum slowly wears the drum surface by its usage in the printer, and it should be replaced appropriately since it gets worn from contact with the cartridge development brush, cleaning mechanism, and paper. Originals The first example of something, such as a document, photograph or text, etc, which is copied, reproduced or translated to produce others, but which is not itself copied or derived from something else. OSI Open Systems Interconnection (OSI) is a model developed by the International Organization for Standardization (ISO) for communications. OSI offers a standard, modular approach to network design that divides the required set of complex functions into manageable, self-contained, functional layers. The layers are, from top to bottom, Application, Presentation, Session, Transport, Network, Data Link and Physical. PABX A private automatic branch exchange (PABX) is an automatic telephone switching system within a private enterprise. PCL Printer Command Language (PCL) is a Page Description Language (PDL) developed by HP as a printer protocol and has become an industry standard. Originally developed for early inkjet printers, PCL has been released in varying levels for thermal, dot matrix printer, and laser printers. PDF Portable Document Format (PDF) is a proprietary file format developed by Adobe Systems for representing two dimensional documents in a device independent and resolution independent format. PostScript PostScript (PS) is a page description language and programming language used primarily in the electronic and desktop publishing areas. that is run in an interpreter to generate an image. Printer Driver A program used to send commands and transfer data from the computer to the printer. Print Media The media like paper, envelopes, labels, and transparencies which can be used in a printer, a scanner, a fax or, a copier. PPM Pages Per Minute (PPM) is a method of measurement for determining how fast a printer works, meaning the number of pages a printer can produce in one minute. PRN file An interface for a device driver, this allows software to interact with the device driver using standard input/output system calls, which simplifies many tasks. Protocol A convention or standard that controls or enables the connection, communication, and data transfer between two computing endpoints. PS See PostScript. PSTN The Public-Switched Telephone Network (PSTN) is the network of the world's public circuit-switched telephone networks which, on industrial premises, is usually routed through the switchboard. RADIUS Remote Authentication Dial In User Service (RADIUS) is a protocol for remote user authentication and accounting. RADIUS enables centralized management of authentication data such as usernames and passwords using an AAA (authentication, authorization, and accounting) concept to manage network access. Resolution The sharpness of an image, measured in Dots Per Inch (DPI). The higher the dpi, the greater the resolution. SMB Server Message Block (SMB) is a network protocol mainly applied to share files, printers, serial ports, and miscellaneous communications Glossary_ 64
