Term Definition
Butane (C4H10) A saturated hydrocarbon (alkane) with four carbon atoms in it’s molecule
(C
4
H
10
). A gas at atmospheric pressure and normal temperature, but easily
liquefied by pressure. Generally stored and delivered in liquefied form and
used as a fuel in gaseous form, obtained by processing natural gas as
produced and also from a process in petroleum refining. Contains
approximately 3,260 Btu per cubic foot.
Byte A group of binary digits that combine to make a word. Generally 8 bits.
Half byte is called a nibble. Large computers use 16 bits and 32 bits. Also
used to denote the amount of memory required to store one byte of data.
Cache Memory Fast memory used to improve the performance of a CPU. Instructions that
will soon be executed are placed in cache memory shortly before they are
needed. This process speeds up the operation of the CPU.
Calibrate To ascertain, usually by comparison with a standard, the locations at which
scale or chart graduations should be placed to correspond to a series of
values of the quantity which the instrument is to measure, receive or
transmit. Also, to adjust the output of a device, to bring it to a desired value,
within a specified tolerance for a particular value of the input. Also, to
ascertain the error in the output of a device by checking it against a
standard.
Capacitor An electronic component that stores electrical charge.
Capacity The total number of ampere-hours (or watt-hours) that can be withdrawn
from a cell/battery under specified conditions of discharge.
Carbon Base of all hydrocarbons and is capable of combining with hydrogen in
many proportions, resulting in numberless hydrocarbon compounds.
Carbon Dioxide Colorless, odorless and slightly acid-tasting gas, consisting of one atom of
carbon joined to two atoms of oxygen. C02. Produced by combustion or
oxidation of materials containing carbon.
Catalytic The process of altering, accelerating or instigating a chemical reaction.
Cathode An electrode through which current leaves any nonmetallic conductor. An
electrolytic cathode is an electrode at which positive ions are discharged,
or negative ions are formed, or at which other reducing reactions occur.
The negative electrode of a galvanic cell; of an electrolytic capacitor.
