信息 什么叫“信息”?信息论和控制论创始人之一的N·维纳说:“信息是人们在适应外部世界并使这种适应反作用外部世界的过程中,同外部世界交换的内容的名称。”也有人称:“所谓信息,就是人与人之间传递的所有符号。”信息与数据概念既有密切的联系,又有区别。数据是以数字、文字(如英文字母、汉字等)或者其它符号(如四则运算符号、标点符号等)所表示的对于客观事物及其变化的描述,也就是由人或机器记录 Information What is “information?” N · Wiener, one of the founders of information theory and cybernetics, said: “Information is the name of the content that people exchange with the outside world in adapting and adapting this adaptation to the outside world Some people also said: ”The so-called information, is all the symbols passed between people." The concept of information and data are closely linked, there are differences. The data is a description of the objective things and their changes represented by numbers, words (such as English letters, Chinese characters, etc.) or other symbols (such as four arithmetic symbols, punctuation, etc.), that is, human or machine records
