command interpreter
command interpreter. A program that accepts commands for control of a subsystem or
utility and that either executes those commands or sends them to the program that will
execute them. Command interpreters are most commonly used interactively, by human
users, but most can also accept input in other ways—for example, from command files.
communications line interface processor (CLIP). The major programmable device within
the ServerNet wide area network (SWAN) concentrator, providing link-level protocol
and a software interface to the host. The CLIP stores and implements specific
communications protocols.
communications network management (CNM) interface. A programmatic interface for
the SNAX/XF subsystem. Programmers can use CNM to request configuration and
statistical information maintained by the subsystem and the Systems Network
Architecture (SNA) host.
communications subsystem. The combination of data communications hardware and
software processes that work together to provide services and access to wide area
networks (WANs) and local area networks (LANs).
Compaq TSM. A product name modifier that identifies a client or server software
component used to manage or service NonStop S-series servers.
Compaq TSM package. A software product for NonStop S-series servers that provides the
information needed to perform functions such as querying resources and testing,
provides notification of problems on the system, and allows local or remote access to
the system for service and maintenance. TSM performs the same role as that of
TMDS, Syshealth, and Remote Maintenance Interface (RMI) on earlier NonStop
systems.
configuration. (1) The arrangement of enclosures, system components, and peripheral
devices into a working unit. (2) The definition or alteration of characteristics of an
object.
configuration management. The task of defining and maintaining records of system and
object
configurations.
connection. The path between two protocol
modules that provides reliable stream delivery
service.
connectionless. Characterized by the absence of logical connections between
communicating entities. Connectionless operation requires that the data itself contain
all the context information—such as addresses—required to get it to its destination and
identify it to the recipient. Higher levels of protocol, or the application itself, are
responsible for message sequencing and error handling. Contrast with connection-
oriented.
connectionless network protocol (CLNP). A protocol for communication across
subnetworks of a larger network. CLNP is defined as the Open Systems
Interconnection (OSI) Internet Protocol (IP) and is implemented as part of HP OSI/TS.
