In computer networking and telecommunications, a broadcast communication network is a communication network which uses broadcasting for communication between its nodes. They take messages from a single sender and transmit to all endpoints on the network. For example, radio, television, etc.

In computer networking, multicast is a type of group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast differs from physical layer point-to-multipoint communication.
In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer: the layer most closely associated with the physical connection between devices. The physical layer provides an electrical, mechanical, and procedural interface to the transmission medium. The shapes and properties of the electrical connectors, the frequencies to transmit on, the line code to use and similar low-level parameters, are specified by the physical layer.
In computer science, inter-process communication (IPC), also spelled interprocess communication, are the mechanisms provided by an operating system for processes to manage shared data. Typically, applications can use IPC, categorized as clients and servers, where the client requests data and the server responds to client requests. Many applications are both clients and servers, as commonly seen in distributed computing.
Wireless communication is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phenomena, such as light and magnetic or electric fields, or the use of sound.
SIGCOMM is the Association for Computing Machinery's Special Interest Group on Data Communications, which specializes in the field of communication and computer networks. It is also the name of an annual 'flagship' conference, organized by SIGCOMM, which is considered to be the leading conference in data communications and networking in the world. Known to have an extremely low acceptance rate (~10%), many of the landmark works in Networking and Communications have been published through it.
In the context of telecommunications, a terminal is a device which ends a telecommunications link and is the point at which a signal enters or leaves a network. Examples of terminal equipment include telephones, fax machines, computer terminals, printers and workstations.
A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment of equipment in the field. There are two types of duplex communication systems: full-duplex (FDX) and half-duplex (HDX).
A computer network is a set of computers sharing resources located on or provided by network nodes. Computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.
Special Telecommunication Service is the Romanian institution that coordinates the activities in the field of special secure communications. STS is an agency with military status.
A communication endpoint is a type of communication network node. It is an interface exposed by a communicating party or by a communication channel. An example of the latter type of a communication endpoint is a publish-subscribe topic or a group in group communication systems.
Garlic routing is a variant of onion routing that encrypts multiple messages together to make it more difficult for attackers to perform traffic analysis and to increase the speed of data transfer.
In communication, media are the outlets or tools used to store and deliver content; semantic information or subject matter of which the media contains. The term generally refers to components of the mass media communications industry, such as print media, publishing, news media, photography, cinema, broadcasting, digital media, and advertising.
Underwater acoustic communication is a technique of sending and receiving messages in water. There are several ways of employing such communication but the most common is by using hydrophones. Underwater communication is difficult due to factors such as multi-path propagation, time variations of the channel, small available bandwidth and strong signal attenuation, especially over long ranges. Compared to terrestrial communication, underwater communication has low data rates because it uses acoustic waves instead of electromagnetic waves.
Wired communication refers to the transmission of data over a wire-based communication technology. Wired communication is also known as wireline communication. Examples include telephone networks, cable television or internet access, and fiber-optic communication. Most wired networks use Ethernet cables to transfer data between connected PCs. Also waveguide (electromagnetism), used for high-power applications, is considered wired line. Local telephone networks often form the basis for wired communications and are used by both residential and business customers in the area. Many networks today rely on the use of fiber optic communication technology as a means of providing clear signaling for both inbound and outbound transmissions and are replacing copper wire transmission. Fiber optic technology is capable of accommodating far more signals than copper wiring while still maintaining the integrity of the signal over longer distances.
ISO 1745:1975 Information processing – Basic mode control procedures for data communication systems is an early ISO standard defining a Telex-oriented communications protocol that used the non-printable ASCII transmission control characters SOH, STX, ETX, EOT, ENQ (Enquiry), ACK (Acknowledge), DLE, NAK, SYN, and ETB.
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any variation of a physical quantity. The protocol defines the rules, syntax, semantics, and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both.
Communication Shutdown is a global fundraiser on behalf of autism-related organizations in more than 40 countries. Beginning in 2010, the day is commemorated by individuals voluntarily refraining from using social media such as Facebook or Twitter for one day on 1 November.
Sup'Com, founded in 1998, is the main school of educating engineers in telecommunications in Tunisia. It is affiliated to the University of Carthage and occupies the advanced ranks in the competitive examination for the access to the engineering studies.
First Nations Experience (FNX) is a non-profit television network in San Bernardino, California, owned by the San Bernardino Community College District. The network, created by Executive Director Charles Fox, is broadcast from the KVCR-TV studios located on the campus of San Bernardino Valley College. FNX is America's first and only broadcast network aimed at Native Americans and global Indigenous audiences and consumers of Native American culture.
LTE-M or LTE-MTC, is a type of low-power wide-area network radio communication technology standard developed by 3GPP for machine-to-machine and Internet of Things (IoT) applications. LTE-M includes eMTC, also known as LTE Cat-M1, whose specification was frozen in 3GPP Release 13, in June 2016.
