Resident Fonts The printers standard typefaces and, for laser printers the standard
point sizes and print orientations for each typeface. For example, Courier 10, 12 (P/
L) means that the typeface Courier is available in sizes 10 point and 12 point and in
portrait and landscape modes. Fonts may be scalable, meaning that they are available
in virtually any point size.
Ring topology A layout scheme in which the network takes the form of a closed
loop with the devices attached into the ring. Every workstation is linked to two others,
one on each side. All data is passed from node to node in one direction only, each
PC acting as a repeater for the next one in the loop. Response time is determined by
the number of stations on the ring - the more there are, the slower it works. If one PC
fails, the loop is broken, though most rings have self-healing capacity to reconfigure
and continue operation. IBM's Token passing ring ensures that the failed station is
removed and its neighbors are then directly connected.
Ring in and Ring out Token Ring connectors on the MSAU connecting the unit to
trunk cabling. The Wrap feature is implemented at these interfaces.
RIP (Raster Image Processor) A device that translates the instructions for the printing
of a page into actual patterns of dots (i.e. raster) needed by the printer in order to
image the page.
RISC (Reduced Instruction Set Computing) A computer system with a special
microprocessor that processes fewer instructions, and thereby is much faster. A
RISC system depends on software to perform many of the functions that would
normally be done by the microprocessor. RISC workstations are used in calculation
intensive operations such as those performed by computer aided design (CAD) and
computer aided manufacture (CAM) engineers.
RMON (Remote Monitoring) SNMP specification for multivendor statistics-gathering
by a standards-based (de facto SNMP) management station from de facto standard
(RMON)-compliant devices.
RJ11 Popular name for the standard four-wire modular connector for phone
connections.
RJ45 Popular name for the eight-pin modular connector in the 10BaseT standard for
UTP connections to workstations or smart wiring hubs. The actual connector is
described in ISO standard 8877.
