In telecommunications and computer networking, a communication channel or channel, refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel. A channel is used to convey an information signal, for example a digital bit stream, from one or several senders (or transmitters) to one or several receivers. A channel has a certain capacity for transmitting information, often measured by its bandwidth in Hz or its data rate in bits per second.
Communicating data from one location to another requires some form of pathway or medium. These pathways, called communication channels, use two types of media: cable (twisted-pair wire, cable, and fiber-optic cable) and broadcast (microwave, satellite, radio, and infrared). Cable or wire line media use physical wires of cables to transmit data and information. Twisted-pair wire and coaxial cables are made of copper, and fiber-optic cable is made of glass.
Channel, channels, and similar terms may refer to:
Communication (from Latin commūnicāre, meaning "to share") is the purposeful activity of information exchange between two or more participants in order to convey or receive the intended meanings through a shared system of signs and semiotic rules. The basic steps of communication are the forming of communicative intent, message composition, message encoding, transmission of signal, reception of signal, message decoding and finally interpretation of the message by the recipient.
Communication in general takes place inside and between three main subject categories: human beings, living organisms in general and communication-enabled devices (for example sensor networks and control systems). Communication in the category of living organisms (studied in the field of biosemiotics) usually occurs through visual, auditory, or biochemical means. Human communication is unique for its extensive use of language.
Nonverbal communication describes the process of conveying meaning in the form of non-word messages. Examples of nonverbal communication include haptic communication, chronemic communication, gestures, body language, facial expression, eye contact, and how one dresses. Nonverbal communication also relates to intent of a message. Examples of intent are voluntary, intentional movements like shaking a hand or winking, as well as involuntary, such as sweating. Speech also contains nonverbal elements known as paralanguage, e.g. rhythm, intonation, tempo, and stress. There may even be a pheromone component. Research has shown that up to 55% of human communication may occur through non-verbal facial expressions, and a further 38% through paralanguage. It affects communication most at the subconscious level and establishes trust. Likewise, written texts include nonverbal elements such as handwriting style, spatial arrangement of words and the use of emoticons to convey emotion.

On June 17, 1985 at 3pm EST, John Hendricks' vision became a reality as Discovery Channel debuted to 156,000 subscribers across the United States. Iceberg Alley, the network's first program, was a documentary about the frigid waters of the North Atlantic and even prompted a call from a teacher in Kansas inquiring about showing the program to her students.

In today's over-messaged world, it's not about sending more messages. It's about sending the most relevant messages to the right customers in the best ways possible. And this requires better customer understanding and greater consistency in correspondence across multiple channels. Retailers are finding new ways to unify content and use rules-based logic to break down silos, unify messaging across their organizations, and more effectively utilize both campaign and transactional communications for greater efficiency and better outcomes.
