Definition of Channel

Channel
see Marketing Channels.

CHANNEL
A "vacation" or void in a cement squeeze job allowing salt water or other fluid into the production zone or another interval in the annular space. Also, in water-flooding, a natural void or "path" in a formation permitting the injection fluid to break through to a producing well from the injection well subverting the water-flooding project. See Squeeze a Well.

Channel
A specified frequency for communication between train and dispatcher or 2 trains. The channel numbers (07 thru 97) are shorthand methods of designating assigned radio frequencies for transmission. For example, channel 96 means to transmit on an assigned radio frequency of 161.550 mHz.

channel
Internet content that is aggregated for a specific category or content provider. Making a poor analogy to television, push channels are content channels delivered through Internet push technology. See also push.

channel
<chat> (Or "chat room", "room", depending on the system in question) The basic unit of group discussion in chat systems like IRC. Once one joins a channel, everything one types is read by others on that channel. Channels can either be named with numbers or with strings that begin with a "#" sign and can have topic descriptions (which are generally irrelevant to the actual subject of discussion).
Some notable channels are "#initgame", "#hottub" and "#report". At times of international crisis, "#report" has hundreds of members, some of whom take turns listening to various news services and typing in summaries of the news, or in some cases, giving first-hand accounts of the action (e.g. Scud missile attacks in Tel Aviv during the Gulf War in 1991).

Channel
the region of a field effect transistor that conducts or blocks the flow of current when the device switches on and off respectively. See also,  Metal Oxide Semiconductor.

channel
n. [IRC] The basic unit of discussion on IRC. Once one joins a channel, everything one types is read by others on that channel. Channels are named with strings that begin with a `#' sign and can have topic descriptions (which are generally irrelevant to the actual subject of discussion). Some notable channels are #initgame, #hottub, callahans, and #report. At times of international crisis, #report has hundreds of members, some of whom take turns listening to various news services and typing in summaries of the news, or in some cases, giving first-hand accounts of the action (e.g., Scud missile attacks in Tel Aviv during the Gulf War in 1991).

Channel
The color in an RGB image is divided into channels, one each for the red, green, and blue information in the image. When these channels are combined, a full-color image results. Certain effects are easier to achieve by manipulating individual color channels. Additional alpha channels can also be added for specifying transparency and selections (see alpha channel).

Channel
Transmission line that can carry the sound of a separate MIDI instrument. Each MIDI port allows up to 16 separate channels for sending or receiving data. Each channel can function as a separate instrument in an ensemble, each using its own patch and responding independently to continuous controllers. (See also MIDI). 

Channel has another meaning on the World Wide Web.  (See Webcasting.)

Channel, MIDI
An information pathway through which MIDI information is sent. MIDI provides for 16 available channels, each of which can address one MIDI instrument.

Channel
One piece of information stored with an image. True color images, for instance, have three channels-red, green and blue.

Channel
A point-to-point link whose task is to transport data from one point to another.

channel
An electrical signal path. In analog audio (such as a mixer), each channel consists of separate wired components. In the digital domain, channels may share wiring, and are kept separate through logical operations. MIDI provides definitions for 16 channels, which transmit not audio signals but digital control signals for triggering synthesizers and other devices.

channel
Virtual area where Internet Relay Chat (IRC) users communicate in real time. There are thousands of channels located on the Internet.

CHANNEL
This is used to describe the capabilities of the software or hardware you are using. Basically when recording a song different instruments are placed on different channels. Most people equate tracks with channels but technically they are different. MIDI devices generally have 16 channels, meaning 16 different instruments can be sounded at one time. eg A piano might be recorded on channel 1, a bass guitar on channel 2, a saxophone on channel 3 etc. People who want a full orchestra may require up to 64 channels, because they want up to 64 separate instruments to play at once. Also see tracks.

To form a channel in; to cut or wear a channel or channels in; to groove.
  
(v. t.)
To course through or over, as in a channel.
  
(n.)
The hollow bed where a stream of water runs or may run.
  
(n.)
The deeper part of a river, harbor, strait, etc., where the main current flows, or which affords the best and safest passage for vessels.
  
(n.)

(n.)
Flat ledges of heavy plank bolted edgewise to the outside of a vessel, to increase the spread of the shrouds and carry them clear of the bulwarks.
  
(n.)

CHAN
Channel

Channel
The width of the spectrum band taken up by a radio signal, usually measured in kilohertz (kHz). Most analog cellular phones use 30-kHz channel.

Channel
That part of a communication chain in which signals are transmitted from a sender to a receiver. Unlike other processes in a communication chain (e.g., encoding, decoding , translation , transformation ), a channel involves a single physical medium that spans the difference in time and in space which separates senders from receivers. A memory is that special case of a channel in which the sender transmits signals to himself at a later point in time. A channel is characterized by the physical properties of its medium and imposes a constraint on the capacity for communication: (1) its selective capability to store, retain, and transmit certain kinds of signals, (2) its sensitivity to non-systematic distortions and decay (see noise, equivocation , redundancy ) and (3) its capacity to transmit information. Primary channels in unaided human communication are audio (largely verbal and musical), visual (largely non-verbal and icon ic) and tactile. In modern society channels are differentiated mainly by the technical devices used, e.g., writing, printing, telephone, photography, television (video and audio channels), satellite communication, computer networks. Each has its own limitations and properties. It is well established that the social reliance on particular channels of communication profoundly influences how a society administers itself, develops and expands. (Krippendorff )

Channel
In wireless, a designated radio frequency available for use by the transmitter and receiver. In audio, the circuit path for a specific signal, or a functional unit that is designed to independently process a signal.

Channel

CHANNEL (LAKE BASIN)
The deeper, narrow elogated or more sharply trenched part of a lake bottom.

CHANNEL (LAKE)
In instances sub-lacustrine channels appear where a lake has been formed by the submergence of a valley, or the drowning of a river; the channels formed under subaerial conditions by stream cutting may remain unfilled by sediments, on the lake bottom.  Channel is applied to a surface water way, either natural or artificial, which connects two lakes and provides for boat travel; to river distributaries and connecting water in a delta; and to trench-like excavations extended inland from a lake shoreline to provide water frontages and boat access for back lots.

CHANNEL (WATERCOURSE)
A natural stream that conveys water; a ditch or channel excavated for the flow of water. River, creek, run, branch, anabranch, and tributary are some of the terms used to describe natural channels, which may be single or braided. Canal, aqueduct, and floodway are some of the terms used to describe artificial (man-made) channels.
