Term Definition
Central Processing Unit The central part of a computer system that performs operations on data. In
a personal computer the CPU is typically a single microprocessor
integrated circuit.
Certification The process of submitting equipment to specific tests to determine that the
equipment meets the specifications or safety standards.
Characteristics Detailed information pertaining to it’s description. The XFC stores this
information in the PROM chip. A feature or quality that makes somebody
or something recognizable.
Charge The conversion of electrical energy, provided in the form of a current from
an external source, into chemical energy within a cell or battery.
Chip Another name for integrated circuit or the piece of silicon on which
semiconductors are created.
Chromatograph An instrument used in chemical analysis, to determine the make-up of
various substances, and often used to determine the Btu content of natural
gas. Chromatography- A method of separating gas compounds by
allowing it to seep through an adsorbent so that each compound is
adsorbed in a separate layer.
CIM Communication Interface Module. Totalflow’s version is called TFIO
Communication Interface Module.
Circuit 1. The complete path between two terminals over which one-way or two-
way communications may be provided. 2. An electronic path between two
or more points, capable of providing a number of channels. 3. A number of
conductors connected together for the purpose of carrying an electrical
current. 4. An electronic closed-loop path among two or more points used
for signal transfer. 5. A number of electrical components, such as
resistors, inductances, capacitors, transistors, and power sources
connected together in one or more closed loops.
Circuit board Sometimes abbreviated PCB. Printed circuit boards are also called cards.
A thin plate on which chips and other electronic components are placed.
They fall into the following categories:
•
Motherboard: Typically, the mother board contains the CPU, memory
and basic controllers for the system. Sometimes call the system board
or main board.
•
Expansion board: Any board that plugs into one of the computer's
expansion slots, including controller boards, LAN cards, and video
adapters.
•
Daughter Card: Any board that attaches directly to another board.
•
Controller board: A special type of expansion board that contains a
controller for a peripheral device.
•
Network Interface Card (NIC): An expansion board that enables a PC
to be connected to a local-area network (LAN).
Video Adapter: An expansion board that contains a controller for a
graphics monitor.
