A relay network is a broad class of network topology commonly used in wireless networks, where the source and destination are interconnected by means of some nodes.In such a network the source and destination cannot communicate to each other directly because the distance between the source and destination is greater than the transmission range of both of them, hence the need for intermediate ...
Communications data (sometimes referred to as traffic data or metadata) concerns information about communication. [1] Communications data is a part of a message that should be distinguished from the content of the message. It contains data on the communication's origin, destination, route, time, date, size, duration, or type of underlying ...
Communication is commonly defined as the transmission of information.Its precise definition is disputed and there are disagreements about whether unintentional or failed transmissions are included and whether communication not only transmits meaning but also creates it.
Paths of communication can be physical (e.g. the road as transportation route) or non-physical (e.g. networks like a computer network). Contents of communication can be for example photography, data, graphics, language, or texts. Means of communication in the narrower sense refer to technical devices that transmit information. [5]
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.
It explains communication in terms of five basic components: a source, a transmitter, a channel, a receiver, and a destination. The source produces the message. To send the message, it has to be translated into a signal by the transmitter. To transmit this signal, a channel is required. At this stage, noise may interfere with the signal and ...

Telecommunication is a compound noun of the Greek prefix tele-(τῆλε), meaning distant, far off, or afar, [7] and the Latin verb communicare, meaning to share. Its modern use is adapted from the French, [ 8 ] because its written use was recorded in 1904 by the French engineer and novelist Édouard Estaunié .
