In the FedWiki, communication is primarily one way but with no push or pull. There is no way to intervene, interrupt, disagree. However, if another interacts with another's communicated item, the originator may choose to view the others thinking.

Communication (from Latin: communicare, meaning "to share" or "to be in relation with") is "an apparent answer to the painful divisions between self and other, private and public, and inner thought and outer world." As this definition indicates, communication is difficult to define in a consistent manner, because in common use it refers to a very wide range of different behaviours involved in the propagation of information.

In its broadest sense, communication refers to all die processes by which one system, human or machine, animate or inanimate, may affect another. Its means indude speaking, writing, gesturing, radio and television broadcasting, artistic expression, electronic and manual switching, computer operations, and many others. All communication occurs in time and in a medium: air, wires, print, light bands, etc. It may be a one way or an interactive process. Much communication takes place by means of symbols, e.g. a word is a symbol for a perception of an object or a sensation. Information is 'what' is communicated and it can be measured quantitatively. It has been said that two people who are aware of each other's proximity cannot 'not communicate’ because even a decision to remain silent is a communication conveying information. In the sense of the technical problem described by Shannon and Weaver ("How accurately can the symbols of communication be transmitted?"), communication may be defined as a process whereby a message is transmitted from a source,through a transmitter,over a communication channel to a receiver to its destination. Noise may drown out portions of the message or portions may be lost. For this reason, redundancy may be added to a message until a given probability of accuracy is reached. Shannon and Weaver's other two levels of communications problems, the semantic problem dealing with the meaning conveyed and the effectiveness problem dealing with whether the desired conduct took place, involve more complexity in the response made by the receiver. # SOURCE Shannon, C.

# EXAMPLES • a letter sent, received, read and understood to mean what was intended • a telephone call com pleted • the genetic code across generations • a dance performance • the signal of an automatic timer to a machine # NON-EXAMPLES • an uncoupled signal or switch • a letter sent, received and misunderstood • books that never leave the shelf • a radio message when the receiver is off • hand signals in the dark # PROBABLE ERROR • presuming a message was understood merely because it was received • failure to allow for the effects of noise on a message • static in a wire • irrelevant data • cross-cultural confusion • the effects of a head cold suffered by the intended receiver
