Communication (from Latin commūnicāre, meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.
Information is any entity or form that provides the answer to a question of some kind or resolves uncertainty. It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.
Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is first robustly defined by Jacob Bigelow in 1829 as: "...principles, processes, and nomenclatures of the more conspicuous arts, particularly those which involve applications of science, and which may be considered useful, by promoting the benefit of society, together with the emolument [compensation ] of those who pursue them" .
When technology makes it perfect, art loses.
Brian Eno, as quoted in Wired (January 1999)
Incorrigible humanity, therefore, led astray by the giant Nimrod, presumed in its heart to outdo in skill not only nature but the source of its own nature, who is God; and began to build a tower in Sennaar, which afterwards was called Babel (that is, 'confusion'). By this means human beings hoped to climb up to heaven, intending in their foolishness not to equal but to excel their creator.
Dante Alighieri, De vulgari eloquentia, Chapter VII
Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.
Samuel Johnson, Boswell's Life of Johnson, 18th April 1775.
Lithium-ion (Li-ion) batteries have revolutionised portable consumer electronics from cameras to cell phones to laptops. Validated safety testing of larger, higher-energy installations has paved the way to large-scale stationary applications as well.
