Glossary of Terms
reduced instruction set computer (RISC) A computer whose architecture features a
simplified, hard-wired instruction set.
register An area in the CPU used for storage or mathematical operations.
relation A data structure having a table-like format; also referred to as a table in
relational terminology.
relational A type of data model (offered by Hewlett-Packard as ALLBASE/SQL) that
stores data in independent two-dimensional tables, thus increasing access
and restructuring flexibility.
relative I/O (RIO) A direct file access method that allows individual records to be
deactivated. These inactive records remain on disk, but are ignored in a
logical read operation.
relative record number A number representing the position of a logical record in
relation to the first record in the file. The first record is numbered either 0
or 1, depending on the subsystem or utility being used.
RELOAD To coldload the entire HP 3000 system, including all MPE files, the
accounting structure, I/O configuration tables, and user files from the
backup medium. A RELOAD is normally used when no other coldload
option has succeeded. MPE/iX equivalent is the ISL INSTALL utility.
relocatable binary module (RBM) The smallest unit of output from a compiler. The
compiler determines how RBMs are separated and their content may vary
depending on the compiler used. Data constants are stored in the RBM
along with the code and are non-modifiable.
remote database A centrally located database which users throughout a network can
access and update.
remote job entry (RJE) A Hewlett-Packard program, executed with the RJE command.
It provides an interface between the HP 3000 and other computers using
the IBM 2780/3780 communications protocol. RJE makes the HP 3000
appear to be either an IBM 2780 Data Transmission Terminal or 3780
Data Communications Terminal to the host system, and provides a
complete multiprogramming environment.
remote mode A mode in which a terminal transmits and receives data from a remote (or
host) computer.
remote network Any network in the catenet to which the local node does not belong.
remote node A node that is not physically located where you are and which you
communicate with using data communication.
remote session A session on a different machine.
remote system A computer system physically separated from other computer systems.
remote system console A terminal that provides remote access to the SPU as a system
console or terminal session.
remote terminal A terminal that is indirectly connected to the computer, using a modem
and telephone hook up.
