remote processor
remote processor. A processor in a node other than the node running the ServerNet
cluster monitor process (SNETMON) that is reporting status about the processor.
remote switch. An HP NonStop™ Cluster Switch in a split-star topology that is not directly
connected to the server that you are logged onto. The Compaq TSM Service
Application cannot perform any actions on a remote switch. To perform actions or get
additional information on a remote switch, use the TSM Service Application to log on to
a server that is directly connected to the switch.
remote system. Any system that is not the local system.
reserved symbol. An identifier that is reserved for use by system or compiler language
implementors.
resistance. The measure of opposition to current that limits the amount of current that can
be produced by an applied voltage. Conductors have very little resistance; insulators
have a large amount of resistance. Resistance is measured in ohms.
resource. A component of a computer system that works together with other components to
process transactions. Terminals, workstations, processors, memory, disk drives,
processes, files, and applications are examples of resources.
response. The information or confirmation supplied by a subsystem in reaction to a
command. A response is typically conveyed as one or more interprocess messages
from a subsystem to an application.
RESTORE. A utility for the HP NonStop™ servers that copies files from a backup tape to
disk. See also BACKUP
.
RFC. Request for Comments. Documents compiled by number by the Internet Engineering
Task Force (IETF) that define standards for intercommunication.
RFI. See radio frequency interference (RFI).
RIPC. See remote interprocessor communication (RIPC).
RISC. See reduced instruction-set computing (RISC).
RISC processor. An instruction processing unit (IPU) that is based on reduced
instruction-set computing (RISC) architecture. TNS/R processors contain RISC
processors.
rms. See root mean square (rms).
robot. A media-changer device that transfers an optical disk cartridge from a storage cell to
an optical disk drive for use, then returns the cartridge to the storage cell.
root. See root fileset and root directory. See also super ID.
