Glossary
environment In a systems context, the environment is anything that is not part of the system
itself. Knowledge about the environment is important because of the effect it
can have on the system or because of possible interactions between the system
and the environment.
FEP cable Fluorinated ethylene propylene cable is high-voltage wire that offers
dielectric strength.
ferrule Tip or termination of a fiber-optic bundle.
fiber cable Cable that uses light rather than electricity to transmit data, therefore immune
to electrical noise and can span larger distances than copper coax cable.
IEC International Electrotechnical Commission. IEC 61918 defines standards for
the installation of coax and fiber media.
IEEE Acronym for Institute of Electrical and Electronic Engineers, which specifies a
family of standards for data communications over local and metropolitan
area networks.
I/O Inputs and outputs.
link See data link.
MICE An acronym that stands for Mechanical Ingress Climatic/Chemical and
Electromagnetic. MICE tables define environmental conditions for industrial
facilities to determine the levels of harshness for the implementation of
components. The four primary elements are mechanical characteristics (M),
ingress protection (I), climatic/chemical (C), electromagnetic (E).
modular Being made up of smaller units, or modules, each of which can be developed,
tested, and finished independently before being combined with the others in
the modular unit. Modularity provides the ability to be reconfigured by easily
replacing one module type with another. Modularity also provides the ability to
correct a failure by easily replacing a faulted module with a known good
module.
NAP Refers to Network Access Port, a phone-jack style connector on a device that
allows temporary network access.
network A series of stations (nodes) connecting multiple devices together for the
purposes of exchanging information. A network can be made up of a single
link or multiple links.
node The connection point at which media access is provided.
parallel A configuration of two or more two-terminal components connected between
two points in a circuit with one terminal of each connected to each of the
two points. The same voltage is applied to each component.
