Abstract

In a word, Data consists of statements that reflect reality. A large class of propositions of practical importance are measurements or observations of a variable quantity. Those clauses can include numbers, words, or pictures.In a broad sense, raw data is numbers, characters, images, or other results of devices that convert physical quantities into symbols. Data of this type are usually further processed by humans or entered into computers. In a computer, data is stored and processed there or transferred (output) to another person or computer. Raw data is a relative term; Data processing is usually done in steps, and the “processed data” at one step can be considered the “raw data” for the next step
