A modulator-demodulator is a device used to transmit digital data over an analog channel. It modulates/demodulates a carrier signal in order to encode digital information onto it.
A modem is typically used to transmit computer data over POTS phone lines.
A network protocol used by a network client to obtain its IP address automatically. This is usually done during the bootstrap process of computers or operating systems running on them. The BOOTP servers assign the IP address from a pool of addresses to each client. BOOTP enables 'diskless workstation' computers as well as other networked devices (printers...) to obtain an IP address prior to loading any advanced operating system.
The part of a laser printer that melts the toner onto the print media. It consists of a hot roller and a back-up roller. After toner is transferred onto the paper, the fuser unit applies heat and pressure to ensure that the toner stays on the paper permanently.
This is why paper is warm when it comes out of a laser printer.
Frame-based computer networking technology used in local area networks (LANs). Ethernet defines wiring and signaling for the physical layer, and frame formats and protocols for the media access control (MAC)/data link layer of the OSI model. Ethernet is mostly standardized as IEEE 802.3.
It has become the most widespread LAN technology since the 1990s.
A small circuit board that holds memory.
The Tagged Image File Format (TIFF) is a non compressed bitmap image format, typically produced by scanners.
TIFF images typically include tags defining the characteristics of the image that is included in the file.
Duty cycle is the page quantity which does not affect printer performance for a month. Generally the printer has the lifespan limitation such as pages per year. The lifespan means the average capacity of print-outs, usually within the warranty period. For example, if the duty cycle is 48,000 pages per month assuming 20 working days, a printer limits to 2,400 pages a day.
An Automatic Document Feeder (ADF) is a mechanism that will automatically feed an original sheet of paper so that a printer can scan some amount of the paper at once.
An Intranet is a network using the same protocols of the public Internet but on a private scale, within an organization.
For example a company may have an intranet for sharing informations between employees. That information would not be accessible outside of the company.
