Information

Information is a sequence of symbols that carries a message, a set of items in which meaning is conveyed, or a specified arrangement of complex structures that conveys a message to a receiver.  Information does not exist on its own.  It is contained within something and is coded.  Information can be coded in different forms, i.e., a written sentence on a piece of paper or on a computer disk.  Information has no mass.  It can be transferred, conveyed as a picture, sight, sound, an idea, spoken word, mathematical equation, etc.  For information to exist, there must be a sender and a receiver.  For example, the word “CAT” has no meaning outside a receiver (someone to read it).
