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.
Communicology is the scholarly and academic study of how people create and use messages to affect the social environment. Communicology is an academic discipline that distinguishes itself from the broader field of human communication with its exclusive use of scientific methods to study communicative phenomena.
Also AM radio or AM. Used interchangeably with kilohertz (kHz) and medium wave. A modulation technique used in electronic communication where the amplitude (signal strength) of the wave is varied in proportion to that of the message signal. Developed in the early 1900s, this technique is most commonly used for transmitting an audio signal via a radio wave measured in kilohertz (kHz). See AM ...
Optical communication, also known as optical telecommunication, is communication at a distance using light to carry information. It can be performed visually or by using electronic devices . The earliest basic forms of optical communication date back several millennia, while the earliest electrical device created to do so was the photophone ...
"Shooting the messenger" (also "killing the messenger" or "attacking the messenger" or "blaming the bearer of bad tidings / the doom monger") is a metaphoric phrase used to describe the act of blaming the bearer of bad news, despite the bearer or messenger having no direct responsibility for the bad news or its consequences.
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.
Shoot and scoot: a type of fire-and-movement tactic used by artillery to avoid counter-battery fire. Siege: a military blockade of a city or fortress with the intent of conquering by force or attrition, often accompanied by an assault in the later phase.
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
