right and left.
Diode
A semiconductor that allows current to flow in one direction only.
DIP Switches
A bank of switches typically used in setting the hardware configuration and
base address of an option card.
Direct Current
A current that does not change in direction.
Direct Memory Access
A method by which information can be transferred from the computer
memory to a device on the bus without using the processor.
Discharge
The conversion of chemical energy of a cell/battery into electrical energy
and withdrawal of the electrical energy into a load.
Discharge Rate
The rate, usually expressed in amperes, at which electrical current is
taken from the cell/battery.
Discrete Manifold
Also called Tubing Manifold. Used in instances when the XFC is not
mounted directly on the Orifice, usually pipe mount or wall mount.
Distribution
The act or process of distributing gas from the city gas or plant that portion
of utility plant used for the purpose of delivering gas from the city gate or
plant to the consumers, or to expenses relating to the operating and
maintenance of distribution plant.
Distribution Company

A.G.A. statistics, a distribution company obtains at least 90 percent of its
gas operating revenues from sales to ultimate customers, and classifies at
least 90 percent of mains (other than service pipe) as distribution.
Compare INTEGRATED COMPANY; TRANSMISSION COMPANY, GAS.
