A passageway in a fence, wall, or other barrier which slides, lowers, or swings shut, and is sometime of open construction.
In Indian architecture, a monumental gateway tower to a Hindu temple, usually highly decorative.
A circular opening in a wall, in traditional Chinese architecture.
A monumental Chinese arch or gateway with one, three or five openings, erected at the entrance to a palace, tomb, or processional way; they are usually built of stone in imitation of earlier wood construction.
An elaborately carved ceremonial gateway in Indian, Buddhist and Hindu architecture, with two or three lintels between two posts.
A monumental, freestanding gateway to a Shinto shrine, consisting of two pillars with a straight cross piece at the top and a lintel above it, usually curving upward.

The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.
a projection on a casting; a piece of metal that has hardened in the gating. After being separated from castings, gates are used in the burden in smelting metal.
(Russian, shiber), a closing device in the form of a slide or damper, used to open or close a channel for the flow of liquids or gases. Gates include draft-regulating dampers in the flues of industrial furnaces and boiler installations as well as sluice gates designed to shut off water-intake channels from a river or to close connections between channels. The working member of a slidingvane pump is also a type of gate. Small gates are operated manually; large gates are operated by toothed racks, worm drives, and the like.

What does it mean when you dream about a gate?
Gates represent entrances to a new place or new circumstances in life. They also symbolize the “exit” from old, unwanted conditions. (See also Door.)

A movable barrier across an opening in a large barrier, a fence, or a wall.
A circuit having an output and a multiplicity of inputs and so designed that the output is energized only when a certain combination of pulses is present at the inputs.
A circuit in which one signal, generally a square wave, serves to switch another signal on and off.
One of the electrodes in a field-effect transistor.
An output element of a cryotron.
To control the passage of a pulse or signal.
In radar, an electric waveform which is applied to the control point of a circuit to alter the mode of operation of the circuit at the time when the waveform is applied. Also known as gating waveform.
A device, such as a valve or door, for controlling the passage of materials through a pipe, channel, or other passageway.
A device for positioning the film in a camera, printer, or projector.
The area or component in which the film is held at a fixed relationship to a lens.
The opening in a casting mold through which molten metal enters the cavity. Also known as in-gate.
The position on the extension of the axis of a runway in use above which an aircraft heading toward that runway is required to pass at a time assigned by proper control authority.
A movable barrier of shielding material used for closing a hole in a nuclear reactor.
A metal part in the rear of the cylinder of old-pattern revolvers that was turned out to expose the cylinder for loading.

GAT Extended? Based on IT
[Sammet 1969, p. 139].
A low-level digital
logic component. Gates
functions (e.g. AND
bits of data (e.g. a flip-flop
), and connect and
disconnect various parts of the overall circuit to control the
flow of data (tri-state buffer).
In a CPU
, the term applies particularly to the buffers that
route data between the various functional units. Each gate
allows data to flow from one unit to another or enables data
from one output onto a certain bus

gate(1) A switch that is opened or closed.
(2) A group of transistors that makes up an AND, OR or NOT Boolean logic gate. See Boolean gates, logic gate and gate array.
(3) In a field effect transistor (FET), the gate is the element that acts as a trigger to cause the transistor to switch. In a bipolar transistor, the gate is called the "base." See transistor, FET and MOSFET.
|The Gate in an NMOS Transistor|
|The gate is the trigger line. When pulsed, an electromagnetic field causes the switch to close.|
