Network media refers to the communication channels used to interconnect nodes on a computer network. Typical examples of network media include copper coaxial cable , copper twisted pair cables and fiber-optic cables used in wired networks, and radio waves used in wireless data communications networks.
A network interface controller (NIC) is computer hardware that connects the computer to the network media and has the ability to process low-level network information. For example, the NIC may have a connector for plugging in a cable, or an aerial for wireless transmission and reception, and the associated circuitry.
Personal and social-network communication is supported by digital technology. This means that social and media networks are shaping the prime mode of organization and most important structures of modern society. [2] Van Dijk's The Network Society describes what the network society is and what it might be like in the future. The first conclusion ...
Wired communication refers to the transmission of data over a wire-based communication technology (telecommunication cables). 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 ...
Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications [1] and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual, that enable users to access, store, transmit, understand and ...
An established phone call is an example. A broadcast channel is a channel that provides a broadcasting service, i.e. that sends data addressed to all users in the network. Cellular network examples are the paging service as well as the Multimedia Broadcast Multicast Service.
An optical communication system is any form of communications system that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a message into an optical signal, a communication channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.
A media gateway controller function (MGCF) is a SIP endpoint that interfaces with the SGW over SCTP. It also controls the resources in a Media Gateway (MGW) across an H.248 interface. A media gateway (MGW) interfaces with the media plane of the CS network, by converting between RTP and PCM.
