According to Wikipedia,"In computer science and computer programming, a data type or simply type is a classification identifying one of various types of data, such as real-valued, integer or Boolean, that determines the possible values for that type; the operations that can be done on values of that type; the meaning of the data; and the way values of that type can be stored.""Almost all programming languages explicitly include the notion of data type, though different languages may use different terminology. Common data types may include:integers,booleans,characters,floating-point numbers,alphanumeric strings."
